Grove Beginner Kit for Arduino | SEEEDSTUDIO |

SEEEDSTUDIO asked me through LinkedIn to make a cooperation with them for reviewing a NEW Arduino, the “Grove Beginner Kit for Arduinoproduct which I accepted. Today I received the stuff which in the next days I will play around a bit and create Blog posts (Tutorials) about it, stay tuned…

FIRST impressions:

I ordered it on 28-07-2020 on the site of SEEDSTUDIO and it arrived on 03-08-2020 @02H58 PM, delivered by DHL. Actually very quick from China to Luxembourg!!

Unpacking my order:

Nice cardboard with lots of TIPS printed on it. The box is sealed with 3 circular glued plastic which I had cut through with scissors, BAD IDEA, as I damaged the cardboard while NOT knowing that the box was meant as a whole playstation as itself (see photos, please)… Here the company could improve please, thanks! My constructive critics! 😉

.

As long as that glued plastic problem ISN’T resolved, use a sharp cutter to cut off the glued circular plastic as I couldn’t remove it by hand!

.


Reading the online Manual

Well, NOTHING to say against it, it is well done!! Please check it here below:

There are professional STEP-BY-STEP instructions so you can’t make mistakes!!

.


Getting started

ALL you have to do is to connect the USB-Cable to the PC, Laptop, which is in the right sight of the box (see step 2 in the PIC below please) to start. [Start Text from WiKi] Grove Beginner Kit for Arduino is one of the best Arduino Beginner Kit for beginners. It includes one Arduino compatible Board and 10 additional Arduino sensors and all in one-piece of PCB design. All the modules have been connected to the Seeeduino through the PCB stamp holes so no Grove cables are needed to connect. Of course, you can also take the modules out and use Grove cables to connect the modules. You can build any Arduino project you like with this Grove Beginner Kit For Arduino. [End Text from WiKi]

Plug and Play Unboxing Demo

The Grove Beginner Kit has a plug and plays unboxing demo, where you first plug in the power to the board, you get the chance to experience all the sensors in one go! Use the button and rotary potentiometer to experience each sensor demo!

  • Scroll -> Rotating Rotary Potentiometer
  • Select -> Short Press Button
  • Exit Current Demo -> Long Press Button

Buzzer and LED module are used for key prompt.

My review

Well, I can recommend this product for beginners by 100%!! Up from the beginning beginners can find out HOW things work with just plugging the USB cable to the PC, Laptop, computer. It’s a GREAT way to bring Coding to STEAM students, Maker’s, MakerED and Maker Spaces!

I didn’t yet using the Breakout possibilities, I DON’T overwhelm you with TOO MUCH information, that will GET discussed in next tutorials, BUT looks promising as NO need to plug single cables, ALL done by ONLY one connector!!!

.

Please check the videos below to understand how the GROVE System works.

..

 


WHERE to order it?

You can GET it here actually (04-08-2020):

TIP for Educators, Teachers, Coaches:

Let the learners first trying the working examples in the box to discover the possibilities! Later you can make the Breakout and then they can reproduce the Coding examples such as mentioned in the online manual.

Two different projects will become ONE project for Xmas

Well, in previous tutorials <===> https://gustmees.wordpress.com/2019/11/03/first-steps-with-the-arduino-uno-maker-makered-makerspaces-coding-make-objects-rotating-with-a-stepper-motor/ <===> and in <===>  https://gustmees.wordpress.com/2018/04/08/first-steps-with-the-arduino-uno-r3-maker-makered-coding-scrolling-text-with-8×8-led-matrix/     <===> we learned about the how-to to make objects rotating as well as to display a scrolling text on a LED Matrix. NOW, we will combine those two for a nice Xmas decoration.

When fixing a small object there isn’t any problem, you just drill a hole of the diameter of the axis of the Stepper-Motor and fix it with hot glue or instant glue. BUT, when it comes to make rotating larger objects it will become unstable!! We need then also a larger support plate to fix the object. I used two techniques, one with a copper-plate of 0.8 mm (was still in my cellar for 30 years…) and/or a single-sided copper-Epoxy plate. Copper-plates are expensive and single-sided copper-Epoxy plates are on a less expensive price. They are about 0.65-1€/piece on Amazon.

For our Xmas project we will use a plastic star with LEDs which will get fixed the following way, check below please.

DC/DC Converter

Up from a certain moment when you get a bit more experience, you start more projects and sometimes you need to resolve a problem. One of those problems could be that you want to feed a project with a 9 Volts battery, accumulator, BUT you need 12 Volts or even more. AND sometimes also less than the 9 Volts. Here comes the need to use a DC/DC Converter. I found a very interesting one on Amazon (DE) for +/- 5€, so cheap investment. It comes even with a 3 digit LED display which shows the voltage which you can adjust through an adjustable trimmer potentiometer. There is also a push-button which allows to show the input voltage as well as the output voltage. No needs to solder, it is a full functional module. All you need is a small screwdriver to adjust the voltage on the potentiometer trimmer. Check out the photo below, please…

.

DC-DC-Converter

.

In above image you can see that the input voltage from the 9 Volts accumulator is at 7.3 Volts which STILL gets a 12 Volts output!! The current could be even on 2.5 Amp (max.) on the output which is a lot!!

 

Stay tuned for next blog posts and enjoy it 😉

Have FUN with your “LEARNing-By-Doing project” and try out ALSO the other examples 😉

Make your Maker-Life less stressful with some tips and tools

You were certainly in some situations where you were shouting and swearing about situations when things didn’t work as well as expected as you didn’t have the right tools to finish a project… Well, I encountered as well such situations on projects and it wouldn’t for sure not be the last time that it will happen… SO, I was browsing internet catalogs about tools and I will present to you the most helpful ones which I found to make my Maker-Life less stressful.

It will be about some special tools as well as about complementary stuff which would be GOOD to have for a BETTER and stress-less working on projects.

Please check below some photos which show you how easy it will become with the shown tools and Tips & Tricks. You will find as well the links to order them in case of… You might choose of course ALSO your favorite supplier…

I strongly recommend the magnetic telescope and the magnetic screwdriver set with bits for any assembling!

Arduino-NANO | DHT22 Temperature/Humidity with Meter

I was looking to find the most easy way to show people and to GET them interested into “Coding” with a minimum of components and expenses, as well as having directly a “success feeling” to be motivated to continue slowly but surely! Here it is; ONLY three (3) wires to connect and ONLY two (2) components to buy for a low budget as well. Temperature and humidity are words well known by everybody and so WE will use a Temperature/Humidity Sensor to run this project. By using terms which the learners know already (Temperature/Humidity) they will NOT GO into “Unknown Land”, makes them feel comfortable 😉

WE will use the tutorial shown below in the video, please check it:

.

.

The link for the tutorial blog is here, please check it:

YOU will find all the necessary information in it such as the how to connecting the components as well as the codes for the “Arduino IDE” and the “Processing code“.

As YOU will remark: there are ONLY three (3) wires to connect, you can count until 3, isn’t it 😉 SO, very easy…

Here below how I did wire it, and you will see how easy it is actually…

.

DHT22-ARDUINO NANO

Click image, please, to enlarge it.

.

You need to install now the Processing software, please check the link below; install it and open it:

Concerning the code for the “Arduino IDE” AND the “Processing IDE“, we will follow the steps on the proposed tutorial…

First copy the code for the Arduino, check below:

.

ARDUINO CODE

Click the image, please, to enlarge

.

Next step: Connect the USB cable to your computer, copy the code, paste it into the Arduino IDE and upload it.

Now copy the “Processing Code”  paste it into the Processing IDE and upload it.

.

PROCESSING CODE

Click the image, please, to enlarge it.

.

IMPORTANT: In the above code in “Line 14” is marked “COM4”! Check if it is the same PORT as in your Arduino IDE, else change the PORT number; for me it was “PORT 8”, but it depends on your computer… JUST change the number, e.g. “COM8”. Click now the button “RUN” on Processing and you will GET the shown result below…

First impressions

Elegoo Smart Robot Car Kit for Arduino.

.

The Kit is delivered in a well organized plastic box with a poster inside of all the parts with description and a CD with the PDF Manual, Code and Libraries.

The manual in PDF format is actually very well documented an nobody should have problems to follow the instructions.

There are even the necessary tools for assembling provided, such as different screwdrivers.

.

 

.


Assembling and cabling

Assembling part 1.

.

.

.

First steps, assembling… Actually it isn’t that difficult, only problem encountered are 2mm screws and nuts, I will continue tomorrow with a magnifying glass and more light to handle it (OH my eyes…). There was some fight with screws and nuts ranging from 1.6mm (Ultrasonic Sensor) to 2mm (Servo fixing) where I needed to use special tools, was a bit stressing to work with such tiny things.

.

.

.

.

.

ToolsFor solving the problems encountered with the tiny screws and nuts, I used a “magnetic telescope” for the 1.6 mm nuts and a “spring-loaded tongs” for the 3 mm nuts.

The cabling was very easy and the rest of the assembling as well as it is VERY well described in the Assembling document (in PDF). Next step is to control (End-Control) again the cabling to make sure that everything is correctly connected and THEN the Coding

The documentation is available in different languages…

.

.

.

.

 

Charger with US plugWhen living in Europe, make sure to make your order on the national platform from Amazon, I made my order in the US and I got the charger delivered with an US plug! Amazon Germany delivers it with an “Euro Plug”! <===>

I made the End Control, checking if the connections were made right, it was.

 

.

Assembling part 2

.

Assembling the two black plates and the wheels was easy peasy as well…

The Coding

Manual on CD

Click the image, please, to enlarge.

Opening the Manual NOW to proceed for the first lesson “Make the car move on [Auto-GO]”. Very easy to follow, it worked in less than 5 minutes. Unplugging the USB cable from the laptop, will it work!?

Taking the car away from the desk and putting it on the floor, switching the Power-supply on and it runs around by avoiding any obstacles while they are detected by the “Ultrasonic Sensor”, it’s FUN watching <===> Success Trying out NEXT lesson now…

The courses are made very easy: plug the USB cable to the computer, open the course in the Arduino IDE, upload it into the IDE, save it in your folder, unplug the USB cable, take the car away from the desk and put it on the floor, switch it on and enjoying…

Well, that’s a Kit which everybody can try and have success, give it a try and enjoy “Coding”, “Maker” activities…

First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Super Starter Kit UNO R3 Project | LCD and Sensors Project

First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Super Starter Kit UNO R3 Project | LCD and Sensors Project

.

Temperature/Humidity Sensor DHT11 and LCD1602

.


Super Starter Kit UNO R3 Project | LCD and Sensors Project | Temperature/Humidity Sensor DHT11

SO, as I got my new Super Starter Kit UNO R3 Project I am playing around a bit with it. In my previous post WE were wiring and testing a LCD-Display and coding to display a bit text on the LCD. That was actually very easy, so lets try out now some “Sensors“, e.g. a Temperature/Humidity Sensor and a Ultrasonic Sensor to measure distances. The measured values of those sensors will get displayed on the LCD-Display.

Let us start first with the Temperature/Humidity Sensor DHT11 which is included in the Kit:

WE will use the following tutorial from Dejan Nedelkovski (How To Mechatronics) as it is very well documented and explained (no need for me to create a new one…). First we will check the video below, please, where we will get explained the How-To and some theoretical explications:

.

.

SO, now after knowing what will be necessary to do, we will first make the wiring of the LCD-Display, please check below:

.

LCD1602-Wiring with Arduino

Click the image above please to access the tutorial

.

As you can see in the above wiring diagram, there isn’t that much wiring to do. When following the tutorial <===> Arduino LCD Tutorial <===> you will get proposed some examples of code to play around with. Try them out to repeat the learned from previous blog post or just leave the wiring as it is to proceed to the next step, the wiring of the Temperature/Humidity Sensor DHT11.

We will continue to follow the tutorial <===> DHT11 & DHT22 Sensors Temperature and Humidity Tutorial using Arduino <===> where the Temperature/Humidity Sensor DHT22 is used. As we use DHT11, you need only to forget about the resistor as it is not needed, replace it by a connection cable (strip).

.

DHT22-Wiring Diagram

Click the above image please to access the tutorial

.

The wiring ready now, we go for the coding. The sketch is available here <===>  DHT11 & DHT22 Sensors Temperature and Humidity Tutorial using Arduino <===> Upload it into the Arduino IDE and give it a try. You will see the result as shown in the image below:

.

DHT22 Code for DHT11

.

There is something strange on the displayed values, isn’t!? WHAT happend!? Let us make some trouble-shooting: the wiring is OK, otherwise the wouldn’t be anything displayed, is the sensor defective!? If you have a second one, replace it to make sure. Same results again, hmmmm!? OK, it’s mysterious on some way, but there must be a solution for it… Let us check the sketch, the code, again to try to understand WHAT the Arduino is getting told to do and WHY the display shows something completely different, the problem is certainly then in the code. Let us review the video tutorial, perhaps we missed something (I did…). In the video, if really listened to, it get explained the two possibilities, using a sensor DHT11 or a DHT22. The code is written for a DHT22 sensor and we use a DHT11 sensor; so WHAT to change now in the code!? Please check the screenshot of the sketch below:

Once change that code line upload it to the Arduino IDE and see WHAT happens on the LCD-Screen. See PIC below please.

.

Temperature/Humidity Sensor DHT11 and LCD1602

.

Well, that’s success!! It works correctly now 😉 Play around with it to see the difference on the LCD-Display while blowing on the sensor. Give it a bit time that the measured values go back again to the previous shown one. SO, as we had now a positive experience and where we can see WHAT is happening on the LCD-Display, let us try another project, we will measure distances with the Ultrasonic-Sensor. But befor we ared going for a NEW project we need to save our project, check the video tutorial below please.

.

 


Super Starter Kit UNO R3 Project | LCD and Sensors Project | Ultrasonic Sensor HC-SR04

We will keep exactly the same wiring diagram for the LCD-Display and taking away the Temperature/Humidity sensor with its wires from the Breadboard. Then we will have a look on the following tutorial, we will use the tutorial from  Dejan Nedelkovski (How To Mechatronics) again, check please <===> http://howtomechatronics.com/tutorials/arduino/ultrasonic-sensor-hc-sr04/ <===> as the previous one was working well! SO, remember that you have to remove the DHT11 Sensor and the wires from it to the Arduino board and follow the next wiring diagram, please. First we will watch the video tutorial.

.

.

Here below the wiring diagram.

.

Next step is to load the code, follow <===> If you want to display the results from the HC-SR04 Ultrasonic Sensor on an LCD you can use the following source code from <===> http://howtomechatronics.com/tutorials/arduino/ultrasonic-sensor-hc-sr04/ <===> and to upload it to the Arduino IDE. That’s it folks, check below please to see the result!

.

ULTRASONIC SENSOR-HC-SR04-and LCD-DISPLAY

.

It works up from the beginning, a success experience! Well folks, as you see it isn’t that much difficult to play around with the Arduino and Coding; don’t forget to save your project so that you can use it again if once needed and try out other projects as well, check the <===> Elegoo UNO R3 Project Super Starter Kit <===> PDF download to GO for NEW LEARNing-By-Doing adventures 😉

Xmas and Holiday Gifts Which Make Sense For LEARNing

Xmas and Holiday Gifts Which Make Sense For LEARNing

.

Maker-Coding

.


WHAT gifts to buy for the kids for Xmas and Holidays?

Every year the same question, isn’t it!? WHY not thinking about to buy gifts from where and with that the kids will learn? It might be good to have a look on WHAT are the skills required for the future from youth, students, learners and upon that making your choice! Actually (2017) the trends are in the maker scene and coding scene! Engineers, coding people and ICT specialists are needed, the workforce, industry is searching!!

What is the maker scene?

I invite you to read my bog post about it below, please:

Variable Power Supply-work in progressIn the Makerspaces as well as in Maker-EDUcation the creativity and PracTICE are getting fostered to be prepared for what the workforce and the industry are needing! The kids, students, learners are Learning-By-Doing and that is with fun involved also! They are not only tinkering around but they get coached in a “NO Hierarchy” space; in Luxembourg. SO, they can communicate with each other to solve problems and as well later also doing the same through the Social-Media and forums. They learn also by that way to build teams and are able for team-work later once out of school.

.

Team-Work is one of the essential skills which students, learners need to have for the future! Read also my blog post below, please, which explains WHAT the skills for the future are:

Learn more by reading my blog posts from Makerspaces in Luxembourg:

In the above blog posts you will find information what is happening and you can contact the responsible persons for more information; let your kids go there and have fun by LEARNing-By-Doing! 😉

What is the coding scene?

Coding is the 21st Century skill. Coding enhances creativity, teaches young people to cooperate, to work together across physical and geographical boundaries and to communicate in a universal language. Technology is part of our life, and coding brings it closer to you!

Makerfest at LTESCH in Luxembourg (Europe)

Kniwwelino

Click image, please, to enlarge

A <===> Makerfest <===> was organized at Lycée Technique ESCH/ALZETTE on 04-07-2017. Over 1.000 persons, apparently 2.000 expected, were present on the second Makerfest at LTESCH (Luxembourg), organized by BEECREATIVE, Service National de la Jeunesse, SCRIPT. Lots of different schools from around the country were present with their students (learners) from any age! As presenters of THEIR MakerSpaces and/or as visitors to take part in the many offered “ateliers”. From 3D Printing, Laser cutting, Green Screen video recordings, Fidget-Spinners making (THAT was THE HIT!), coding with Scratch, LEGO MINDSTORMS and NOT to forget <===> KNIWWELINO <===> a NEW project created by LIST (Luxembourg Institute of Science and Technology) who was specially developed to meet the needs of coding for youth!
It was a pleasure to see with HOW MANY fun the kids and teens were “making” and LEARNing 😉 IF THAT isn’t the future, WHAT else! 😉 I wish I would be that young again to visit such schools 😉

Please check the video below:
