First Steps with the Arduino-UNO | Maker, MakerED, Coding | Sensor-Kit SKA-36

First Steps with the Arduino-UNO | Maker, MakerED, Coding | Sensor-Kit SKA-36

HC-SR04-ULTRASONIC SENSOR.

 


First Steps with the Arduino-UNO | Maker, MakerED, Coding | Sensor-Kit SKA-36

Arduino Sensor-Kit SKA-36.

Got my package delivered with my ordered Arduino Sensor-Kit today (2 days later than expected…). First impressions: nice plastic suitcase (helps me to keep order…), 60 pins quality breadboard and cable-set, 40 sensors and a download link (www.joy-it.net/sensorkit/) for the code and description in German. The mentioned link isn’t up-to-date anymore and one gets redirected to another website http://sensorkit.joy-it.net/index.php?title=Hauptseite in German.

.

.

.

Arduino Sensor-Kit SKA-36-40 sensors

.

Some basic knowledge is necessary to get started with the sensors:

We need to know that for some project with sensors there is a special library which needs to get included into the sketch and that the results (measures) will get shown in the “Serial Monitor” as the “Sensor-Kit” doesn’t include a LCD-Display.

Find out more yourself with the links below, please:

.

TIP for beginners: first copy&paste the code and let it run; check where are variables in the code, change them and see WHAT happens. You will understand the about how the code works 😉

.


KY-050 with Ultrasonic Sensor HC-SR04 and Arduino Tutorial

Well, I didn’t like much the German description, so I was searching on the internet and I found some tutorials in English with a video tutorial, one simple sketch and one sketch with an LCD as well, very interesting <===> Ultrasonic Sensor HC-SR04 and Arduino Tutorial

Please check the videos below who explains very well how the code works:

.

.

Another GREAT tutorial (my favorite), also with a video tutorial from Circuit basics could be found here HOW TO SET UP AN ULTRASONIC RANGE FINDER ON AN ARDUINO

And here below the video tutorial:

The Temperature/Humidity Sensor KY-015

ky-015In the original IDE this sensor isn’t included yet, WE need to install it on the IDE. By checking the description website of the Sensorkit-SK36-KY-015, WE get told that the module needs a library to get included in the sketch and it’s also mentioning some download links. Actually the description (in German) is poor and I got worried! So I decided to look around on the internet and I found a BETTER description (in English) on the official Arduino website <===> Installing Additional Arduino Libraries <===> 

BUT the BEST tutorial I have found is on the Arduino website itself <===> DHT11 Temperature/Humidity Sensor <===> with a lot of screenshots and a step by step instruction from where to get the code of the library, how to install it, and an example sketch.

Maker-First Steps in Electronics-Moving and rotating statue

In OUR previous electronics projects WE were tinkering around with vibration motors and flashing LEDs, well we will continue on the same schema to get a bit more soldering practice and to discover ALSO the use of heat shrink tube. This is ALSO a soldering exercise with some fun, and knowledge acquirement as usually in my tutorials. WE will learn also about Lithium batteries and their power by connecting them in parallel.


OHM’s Law, resistors and LEDs

Practical Tip: LEDs are transparent, so the Cathode (Minus) looks always a bit larger as the Anode (Plus).

.

.

.

When working with electronics WE need to learn a bit theory and mathematics, BUT DON’T worry, it is very easy! First of all which is mandatory, is the “OHM’s Law“. YOU DON’T need to calculate! 😉 There is an online calculator who will do the job for YOU! Click the image below please to access the online calculator and play a bit around with it to get used to it, have fun.

The schematics of our project

Here below the schematics where YOU will see how the components are represented; YOU will remark that we have three (3) times a parallel circuit. Two batteries in parallel, two flashing LEDs in parallel and two vibration motors in parallel.The resistors are NOT shown in the schematic as THEY are NOT connected, they are just used as stabilization of the statue!

.

moving-and-rotating-electronics-statue-schematics-screenshot

.

WHY connecting batteries in parallel!? Check below, please:

To find it out I recommend to make a bit PracTICE:

  1. Try first to use ONLY 1 battery CR2032 and let run the statue.
  2. NOW use two (2) batteries CR2032 and let run the statue.
  3. Use NOW ONLY one (1) battery CR2430 (they are bigger in diameter and on power) and let run the statue.
  4. NOW use two (2) batteries CR2430 and let run the statue.

Both batteries deliver 3 Volts, BUT there is a difference in the possible current they can deliver. The CR2032 delivers 225 mAh and the CR2430 delivers 280 mAh!

Through THIS “Learning-By-Doing” YOU will easily understand it!

Working with heat shrink tube

[START text from Wikipedia] Heat shrink tubing (or, commonly, heat shrink or heatshrink) is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical work. It can also be used to repair the insulation on wires or to bundle them together, to protect wires or small parts from minor abrasion, and to create cable entry seals, offering environmental sealing protection. Heat shrink tubing is ordinarily made of nylon or polyolefin, which shrinks radially (but not longitudinally) when heated, to between one-half and one-sixth of its diameter. [END text from Wikipedia]

Half Square Nut as unbalance

Click image please to enlarge.

.

In previous blog post (tutorial) WE used a vibration motor from an old smartphone and we were learning also about the How-To about a vibration motor is working; it is about “Unbalance“. This unbalance is normally unwanted for motors, but for vibration motors it is a MUST. The motor we used was a 3 Volts motor and very small. In THIS NEW project we will use a 9 Volts DC-Motor and we will create from a normal motor a vibration motor with a little trick.

.

.

..

.

 

Square Nut

.

.

.

We will use a square nut and saw it in the middle, then taking the hot glue pistol and gluing it (one half) on the shaft of the 9 Volts DC-Motor.

.

.

.

.

Learn more:

9 Volts DC Motors are actually very cheap, check below please:

.

 

 


Let us have a look on the unbalance and vibrations motors

A vibrating motor is essentially a motor that is improperly balanced. In other words, there is an off-centered weight attached to the motor’s rotational shaft that causes the motor to wobble. The amount of wobble can be changed by the amount of weight that you attach, the weight’s distance from the shaft, and the speed at which the motor spins.

VELCRO.

.

As you can see there is NOTHING special; we just put five (5) elements (4 flashing LEDS, a vibration motor) in parallel. The motor will get fixed with hot glue on the bottom. And we have a switch to switch on/off our circuit. As battery we use a 9 Volts battery which will get fixed with “VELCRO” on the bottom.

.

.

.

Learn more:

Calculating the resistor value with a 9 Volts battery and knowing that the flashing LEDs will be 3 Volts and consuming 20 mA. SO: 9-3=6 Volts which will get needed to take away from the LEDs. Check below please:

.

The tools needed

Check below please WHAT the tools are that you will need for this project. The small saw is needed to cut out a small piece of 55 x 45 mm from the stripboard. That part is needed for soldering the resistor and the switch and is used to make the necessary connections to the other parts.

Maker-First Steps in Electronics, the basics

Maker-First Steps in Electronics, the basics

.

first-steps-on-electronics-fritzing-layout-strip-board-print-out-sheet

.


Where to start?

platine-hartpapier

Strip-Board

I propose to work with system when WE use strip-boards; thus meaning: preparing them ALL the same way. Any electronics project will need a power supply, so WE will start with the power supply which will mostly be a 9 Volt battery. WE will use the outside strips to connect them to plus and minus and WE will ALSO provide a diode (1N4007) to protect against polarity reversal. As a newbie in electronics this might be the best way to protect you to destroy the electronic parts if + and – would get reversed 😉 With normal rectifier diodes the power supply voltage will typically drop by 0.8 volts. WE will have then ONLY 8.2 Volts which is enough in most cases.

WE will solder also a PCB-Connector (Printed Circuit Board Connector) where we can feed the strip-board with the power supply.

.

SO, as WE will solder a bit, it will be also a soldering training before we start on more serious projects later 😉

Check below please how the finished project will look, which we will discuss in detail on the How-To. WE use a 100 mm x 75 mm strip-board (CONRAD 529531 – 62  for 2,19€).

.

Strip-Board-Power Supply

First steps in electronics

Necessary material

.

screw-terminal-2-pins.

.

In above image I used a 2 pin screw terminal from CONRAD (1192188 – 62) for 0,28€ and for the wire I choose from a “Wire Kit from Velleman” (60 m from different colors).

  • full core, 0.2mm²
  • colours: 5 metres : white / blue / brown / green / yellow / orange / grey / violet + 10 metres : black / red
  • external diameter: 1.4 mm
  • max. voltage: 60 V
  • max. current: 4.3 A
  • PVC insulation
  • tinned CU
  • AWG24

.

abbiegevorrichtung.

To make sure to have proper bent edges; I suggest to bend the diode (1N4007) over the left-hand side shown “Wire Bender” (CONRAD 425869 – 62  at 3,29€).

 

.

.

First start to solder the 2 pin screw terminal in the middle of the strip-board, followed by the diode (1N4007). Now measure the distance and cut the wires. For the red wire (Plus) it will be 4 cm (3 cm distance), the blue wire (Minus) will be 6 cm (5 cm distance). Take the electronics cutter and strip off o,5 cm of the insulation at each end and bend it. Put it into the holes in the strip-board and solder it. P.S.: WE will use the red wire for the Plus (+) and the blue wire for the Minus (-) of the power supply; that are internationally conventions in electronics. Sometimes for the Minus (-) is also used the black color (see 9 Volt battery clip).

When WE want to start with electronics there is a little bit theory to learn as well; in electronics there are special symbols who get used in schematics. Any component (even a battery) has its own symbol. In the following tutorials and projects, WE will learn by easy step-by-step WHAT they are and HOW to make OUR PracTICE (to GET used to it…) with them. I am certainly NOT a friend of learning by heart, BUT symbols need to get learned that way to understand schematics of electronics!

resistor-color-chartAs You have remarked, I added ALSO a resistor and a LED (Light-Emitting Diode); the red (could also bee a green one) LED is lightning when the power supply (9 Volt battery) is connected. SO, YOU might solder the two components (330 Ohm resistor and LED) as well, not mandatory BUT it will give YOU a bit more training on soldering and alerts YOU to NOT solder when it is on!! NEVER work on whatever project with connected (switched on) power supply <===> Safety first!

WHY has the resistor a value of 330 Ohm?

In above example we used a 5 mm red LED with this characteristics: 2.25 Volt and 20 mA current (that’s the maximum values which DON’T have to become higher otherwise the LED will get destroyed) and as power supply we use a 9 Volts battery.  WE will use the “Online Calculator” to calculate the value of the resistor. First let us do some mental calculation, there WE DON’T need any calculator. WE have a 9 Volts battery and the LED will have maximum 2.25 Volts, so “9 V – 2.25 V = 6.75 V” which needs to get taken away from the LED to avoid destruction.

led-series-resistor-calculator-330-ohm

..

THAT value of 337.5 Ohms doesn’t exist! Resistors are manufactured by following <===> In 1952 the IEC (International Electrotechnical Commission) decided to define the resistance and tolerance values into a norm, to ease the mass manufacturing of resistors. These are referred to as preferred values or E-series, and they are published in standard IEC 60063:1963. These standard values are also valid for other components like capacitors, inductors and Zener diodes. The preferred values for resistors were established in 1952, but the concept of the geometric series was already introduced by army engineer Renard in the 1870s.

By checking the below link, WE will see that the closest value is 330 Ohm. BTW: The symbol for “Ohm” is “Ω“; SO, we write 330 Ω. Tip: You find it in the “Special Characters” in any editing software.

In the above website is a video integrated which explains very well about the How-To of that norm, give it a try.

.

framing-in-educationMY experience described in ONLY some phrases: Give the LEARNers, students (whatever age) the freedom of LEARNing without squeezing THEM into a FRAME and concentrate on guiding them as a coach by analyzing THEIR behavior and show them the How-To to become self-directed learners, autodidacts. SHOW THEM ALSO up from the beginning WHAT THE <===> LEARNing Path <===> will be with design of it and explain THEM that they could design themselves it with a short introduction on the How-To. THEY will learn the ICT-PracTICE which will help them once out of the <===> #SchoolCocoon <===> to be ready for Life-Long LEARNing and to be able to adapt very quickly in the workforce! WHEN YOU show the LEARNers, students <===> WHAT the profit is for THEIR private life <===> YOU will engage them very quickly 😉 AND DON’T teach THEM more as necessary, propose them some links to go further ONLY for those who want!!

Check ALSO (Up from 11 years old, give THEM THE confidence THEY need to grow):

.

WHAT’S my message and WHY did I create this blog post!?

Well, I will encourage all youth and also adults, seniors, oldies to become <===>Life-Long LEARNers <===> and staying Up-To-Date with their knowledge, especially concerning their skills in ICT, called NOW <===> #eSkills <===>! In the modern world YOU will change YOUR job probably +/- 12 times in YOUR working career, it is very rare to stay life-long in the same job and/or same company!!! SO… The workforce is looking for people with ICT skills which YOU mostly didn’t learn at school, right!? 

Bring in YOUR kids to such creative makerplaces WHERE THEY can develop (and perhaps parents as well…) THEIR creativity and GET interested in something WHICH could boost THEIR interest into ICT in their future 😉

YOU won’t have (mostly) the time to learn by visiting courses, right!? START to become Life-Long LEARNers by LEARNing on YOUR OWN pace, by becoming <===> Autodidacts <===> Self-Directed LEARNers. YOU are able to, I did it, so can YOU!? 😉

I found a job because of my ICT eSkills and I am STILL LEARNing on a daily base routine for being Up-To Date with my <===> Professional Development <===>, even being retired NOW! THE pleasure of LEARNing!

I did THE <===> ICT PracTICE <===> and THAT’S WHAT the workforce needs!!!


 Due to my eSkills I could share my knowledge AND expertise ALSO with the below mentioned as well as to a broad range of visitors from around the globe!

Hackerspaces-SYN2CAT-LEVEL2

syn2cat-level2-georges-kesseler-10-10-2016.

Today on 10-10-2016 I visited THE pioneer of the Hackerspaces in Luxembourg-City <===> https://level2.lu/ <===> and I was heartily welcomed by Georges KESSELER, the president of this Non-profit Hackerspace (ONG). As already mentioned, I said pioneer, THIS place was the first in Luxembourg. Georges proudly showed me the rooms with ALSO professional explications about the realized projects and what fore THIS place is..

.

A “Hackerspace” is a place where people with similar interests in technology, science, art, culture, and making meet. Activities are not in the slightest restricted to only computer science, but also emerge from electronics, contemporary art, photography, and any and all other pursuits worth sharing. The hackerspace offers a turnkey infrastructure to its members where innovative projects that would not come to life in a garage, can find nourishment and support.

There is ALSO a weekly CoderDojo in Luxembourg at the local HackerSpace every Thursday at 18:00. It is intended for 12-18 Year olds (but younger Kids are welcome too).

Let us talk ALSO about WHAT THAT term of “Hacking” means actually as it is often misunderstood. “Hacking” doesn’t mean ONLY hacking a computer etc., even there is a difference between “Ethical Hacking” (White Hat Hackers) and “Criminal Hacking” (Black Hat Hackers). It refers ALSO to transform something from its ORIGIN meant use to a different one; so TODAY we speak about “Life-Hacks“, “Kitchen-Hacks“, “Cooking Hacks“, “Beauty Hacks“, “Electronic Hacks“, etc.

Some examples for BETTER understanding:


The Interview

Concerning the questions and answers WE will use initials such as:

  • [GM] for Gust MEES
  • [GK] for Georges KESSELER

book-question-mark[GM] I first was asking Georges [GK] WHAT he would like to have as a message from the content of THIS interview. He told me that probably the MOST important would be to find NEW active members able to run projects together with others. As a reminder: The Hackerspace “LEVEL2” is working on the “Open Source Mentality“, read Linux community; there are NO Windows computers and/or devices present. THEY hack around the “RaspBerry PI” ALSO. It’s a “Learning-By-Doing” community, Geeks, and NOT a “Repair shop” for computers as certain people thought it is…

Questions:

  • [GM] How many members do You have?
    • [GK] WE have about 60 members actually.
  • [GM] WHEN did YOUR “ONG” Non-Profit Club got founded?
    • [GK] WE started about 2009 in STRASSEN and moved to Luxembourg-City in 2014 where WE are located now.
  • [GM] WHAT’S the origin of YOUR name “SYN2CAT”?
    • [GK] Read it as “Syndicate”; it’s actually, as it is a Linux community, a derive from the “TCP protocol” where “syn” and “cat” are UNIX and LINUX commands and/or part from a protocol.
  • [GM] WHAT’S the origin of the name “LEVEL2”?
    • [GK] Well, WE are located on the level two in the building 😉 AND ALSO as it is OUR second “Hackerspace” as THE one in STRASSEN closed!
  • [GM] HOW do YOU get financed as a Non-Profit Club?
    • [GK] WE live through the membership fees and some donations.

[GM] Check ALSO the “FAQ’s” please:

https://wiki.hackerspace.lu/wiki/Join!

  • [GM] You are located in the “House of Youth”, “Maison de la Jeunesse”<===> http://maison-jeunesse.lu/, this shows the confidence and importance THEY give to YOUR club. Do YOU have to pay any rent?
    • [GK] We get part of the rent sponsored…
  • [GM] Well, lucky-wise some money that YOU don’t have to spend and which helps a lot to survive. SO, HOW are YOUR projects get financed THEN!?
    • [GK] There are different ways. For private (own) projects: you can use the infrastructure. For Community project you can get full financing:  This funding method is also used for equipment acquisition (video projector, 3D printer)…
  • [GM] Was YOUR initiative as a Hackerspace the ORIGIN of “Makerspaces” in Luxembourg?
    • [GK] YES! One of OUR members, Marc TEUSCH iniated them.

[GM] I have seen a video of Marc TEUSCH on a TEDxLuxembourg presentation WHERE You can find it on my blog <===> https://gustmees.wordpress.com/2014/08/20/maker-space-a-new-trend-in-education-and-a-big-responsibility/

[GM] Marc TEUSCH, WHO is teaching in ETTELBRUCK (Luxembourg) created FIRST Makerspace in Luxembourg (March 6, 2013):

I made ALSO an interview with the responsible people of the EDUcation for “Makerspaces” in Luxembourg and I visited the The flagship makerspace of the national Youth Service SNJ “BASE 1” at Forum Geesseknäppchen in Luxembourg-City. Please check below:

Gunstick) is president of syn2cat asbl, moderates the club’s monthly Lët’z Hack radioshow and is also involved in the recently created HaxoGreen asbl organizing an outdoor hacker event every 2 years. He is a big fan of retro computing and chiptunes having lived himself the era of Amiga and Atari ST and acquired a multitude of skills through self teaching from 3D design over workbench skills to micro-controller programming. In his rare spare time he invites fellow hackers to join into his muscle hacker (think: yoga) sessions or goes on vacation for some extreme roller coaster rides. He likes to give other people insight in his vast know-how on a very large spectrum of subjects. From circus arts over astronomy and laser graffiti to geocaching. You can find him on Facebook and twitter.
