Make objects rotating with a Stepper-Motor | Tips and Tricks

Well, in a previous tutorial <===> https://gustmees.wordpress.com/2018/09/19/halloween-project-with-skull-arduino-blinking-leds-and-scrolling-eyes-maker-makered-makerspaces/ <===> we created a Halloween Skull and it was fix, didn’t rotate. Fun? YES, BUT more fun when it is rotating by using a Stepper-Motor; looks then as it would observe, control the space around it 😉 And it is very easy to create, only a Stepper-Motor, an Arduino NANO and a bit Code; the rest is a bit manual work to fix mechanically the motor. And with the right tools the mechanical work is a piece of cake 😉. We will discuss ONLY the mechanical works and for the the code (Sketch) for the Arduino, please look at the following tutorial:

• Make objects rotating with a Stepper-Motor
• …

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.

The mechanical works

First of all chose on what material you would like to fix the Stepper-Motor: this could be metal, plastic, cardboard or wood. As I like recycling, I ask in the Supermarket to get an empty wooden wine box. The Supermarket sometimes opens a six-pack of wine bottles in a wooden case (box) and they are happy NOT to recycle it themselves 😉 Here below an example for a Halloween project…

.

Desription:

Drill a hole with a 6 mm drill in your support, then use the 32 mm Step-Drill to make the hole diameter fit to the diameter of the Stepper-Motor. Fix the Stepper-Motor. I used a copper-plate for having a large surface to fix the chosen rotating object. The axis from the Stepper-Motor is made from brass and that fits very well with copper for soldering them together. For the soldering you need an 80 Watt solder iron with a temperature of 430° C (806° F). Before you start soldering: clean the copper-plate, take off the patina first!! Same step for the single-sided Copper-Epoxy plate!!

Displaying Time, Date, Temperature and Humidity on a LCD2004 Display

We were already playing around with a LCD2004 display in a previous tutorial where we displayed the temperature and the humidity <===> First Steps with the Arduino-UNO R3 and NANO | Maker, MakerED, Coding | I2C LCD Temp./Humidity displaying, now we will add as well Time and Date with a DS3231 module.

We will use the tutorial from <===> Arduino datalogger with SD card, DS3231 and DHT22 sensor, where we will NOT use the datalogger for our project to make it as easy as possible; courageous ones, once the project is working for them, may add the datalogger 😉 In that tutorial you will find also the code…

Please check video tutorial below:

.

.

Check also the blog below, please:

• https://simple-circuit.com/arduino-datalogger-sd-card-ds3231-dht22/

.

Check the schematic above please to know how to wire it; first we will do it on a breadboard and later we could solder it… Do the wiring as shown, without the Datalogger-SDCard-Module. See PIC below, please.

.

.

In the above image you will see an DHT11 Sensor (blue case) as at the time I didn’t have it yet (was ordered…) a DHT22 Sensor (white case) as shown on the finished project. As the project works we can now solder everything together on a strip-board, choosing a case; I used a cardboard box with the dimensions of 140 mm X 130 mm X 60 mmm, fixing the LCD2004 and the DHT22-Sensor on the front of the cardboard box.

First Steps with the Arduino-UNO R3 | Maker, MakerED, MakerSpaces, Coding | Xmas Star with NeoPixels WS2812B

Xmas Star with NeoPixels WS2812B made from cardboard

Soon there will be Christmas and decorations are getting put around the house worldwide as it is tradition since ages to do so. That’s also the time for tinkerers, makers to GET some new ideas. Well, I thought on a project which everybody could do without having a 3D-Printer NOR a Laser cutter at home and not having access to them on other places. SO, I tried out to create a Xmas-Star from cardboard using an Arduino UNO and Neopixels…

I recently bought 1 Meter of Neopixels WS2812B with 60 LEDs and tried it out while wife was looking at it and she told me if that wouldn’t be an idea for making a Christmas-Decoration, e.g. a star. I took that challenge and a day later it was working, LOL 😉 I used a 3,5 mm thick cardboard from a red wine box which was stable enough to create the project.

 

The measures are 160 mm x 160 mm and there are 8 segments with an angle of 45° (8 x 45 = 360°). This is quiet easy to draw on cardboard… Once the lines drawn, up from the middle line draw a 1 cm to the left and to the right so that it makes a 2 cm width of each segment. On the middle cut out a square hole from 1,6 cm. That is the perfect outfit for the Christmas-Star. Cut it out with a sharp cutter and paint it with the color of your choice, I used green… NOW take the 1 meter long ribbon and cut off 8 x 4 LEDs. THEN take off the protection paper from the Neopixels WS2812B ribbon and glue them on the cardboard, see PIC please.

 

Find below, please, a drawing with the dimensions and where to cut out:

 

You may have a look on this Tutorial to know a bit more about the handling of Neopixel LEDS, please:

• https://www.scoop.it/t/21st-century-learning-and-teaching/?&tag=Neopixel
• …

The project itself by cabling is actually VERY easy, ONLY 3 wires, the MOST work is on the mechanical part by cutting the cardboard, painting, soldering the Neopixels WS2812B strip and to put everything into a box with the necessary parts, while drilling, etc. WE will see this in detail by following PICS… But first let us solder and interconnecting the 8 x 4 Neopixels LEDs strips, you need to follow the arrows on the strips to connect each of the 8 x 4 LED strips, thus meaning: see PICs please:

.

Please have a look on how this will look in our project; we use color flat cable to make the connections.

.

Back side view of the Xmas star: click image, please, to enlarge.

The flat cable will get fixed with hot-glue on the cardboard.

 

Front side view of the Xmas star: click image, please, to enlarge.

.

Once the 8 x 4 LED strips are interconnected, you can connect the other 28 LEDs to the point marked with “START” and connect them to the ARDUINO UNO board through a screw terminal to make the first tests. Please check the tutorial below with the code for the How-To:

• http://frederickvandenbosch.be/?p=359
• …

IF everything is working, hopefully, we can go for the integration of the components into a housing. TIP: prepare the ARDUINO UNO (NANO) already with the code uploaded and test after each 4 LED strips connected to make sure it will work!! it’s BETTER to invest time for NOT later having trouble and NOT knowing from where the fault comes 😉

RFID RC522 Tag-Card Reader with LCD1602-I2C

We were already playing around with LCD’s in our previous tutorial <===> First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Super Starter Kit UNO R3 Project | LCD and Sensors Project <===> but there we used the SPI-Bus, meaning: connecting 12 wires (Potentiometer connections included…)!! With the I2C Bus we need ONLY to connect 4 wires!!

Check PICs below please to see the difference:

SPI Bus connections

.

I2C Bus connections on Arduino UNO

.

.

I2C Bus connections on Arduino NANO

.

.

SO, as you can see there is a BIG difference in cabling 😉 Especially beginners in Coding would appreciate this I2C version with ONLY 4 wires!

Learn more:

• SPI Bus
• I2C Bus
• …

.

Check this video tutorial which explains very well about I2C:

.

.

Let us NOW first watch the video tutorial to see about WHAT this tutorial is…

.

.

The video and the code description in the Sketch are in Portuguese, BUT DON’T worry, I will give you later some screenshots with English text which you will need to change in the code; there are anyway some lines of code to add (change…) to make it working correctly! But let us FIRST have a look on the PINOUT of the RFID RC522 to see WHAT we have to connect.

.

.

So, let us now connect the RFID-RC522 to the Arduino UNO or the Arduino NANO, I used a Arduino NANO and its working perfectly! Check the translated (Google translate) wiring instructions.

.

 

Make sure to connect the RFID-RC522 to 3,3 Volts and NOT to 5 Volts, you will fry the device otherwise!!

.

.

 

 

Click PIC , please, to enlarge.

.

As we can see from the bove there are 7 wires to connect from 8 possible connections on the RFIF RC522 device; the “interrupt pin (IRQ)” isn’t needed! SO, lets connect these pins to the Arduino UNO, or as I did to the Arduino NANO; it works on both! Next step is to connect the LCD1602 I2C to the Arduino, it’s pretty simple, check below please. ONLY 4 wires!

.

.

The wiring done, NOW we can download the code (Sketch) and upload it to our Arduino UNO, or NANO through the Arduino IDE, please find the download link below:

• https://drive.google.com/file/d/0ByKMX29rFLseMllvREdwaVBvVlU/view
• …

Once uploaded (compiling) the code there could be some errors happening, it happens to me… please check PIC below:

 

Click image, please, to enlarge

.

Well I made some searches on the internet and I found the right answer on a forum about this error, which sais that one should scan the I2C Address of the device and replace the “lcd.init();” by “lcd.begin (0x3F,16,2);” whereby “0x3F” is the I2C Address of my LCD1602/I2C module. I scanned to find out the I2C Addess with this sketch, please check here:

• https://playground.arduino.cc/Main/I2cScanner
• …

I bought 3 from Amazon (Germany) delivered from “AZ Delivery” <===>  https://www.amazon.de/gp/product/B079T1BW6T  <===> and they should have had ALL the I2C-Address “0X27” as explained in their FREE eBook <===>  https://bibliothek.az-delivery.de/wp-content/uploads/2018/01/11-AZ-Delivery_16x2LCD-I2C-Display-Bundle_Startertutorial.pdf   <===> but ONLY 1 had this address and two others the I2C-Address “0X3F”!! BTW: AZ Delivery has very GOOD stuff for reasonable prices!

Here below the results of the scan of the I2C-Address, shown in the Serial-Monitor of the Arduino IDE:.

 

Click image, please, to enlarge.

.

Click image, please, to enlarge.

.

SO, make sure to FIRST scan the I2C-Address through the above mentioned Sketch, will save you a lot of stress! 😉

TIP: Use a DYMO, print out the I2C-Addresses and glue them on the backside of the LCD1602 Display, so you know for next projects WHAT I2C-Address the module has! 😉 In a couple of weeks you wouldn’t remind it anymore!

Xmas and Holiday Gifts Which Make Sense For LEARNing

.

.

---

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:

• Maker Space | A New Trend In Education And A BIG Responsibility

• …

In 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:

• WHAT Are THE Skills Needed From Students In The Future!?

• …

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

• Luxembourg EDUcation-Interviews | 5) Creativity and Maker-Spaces | BEECREATIVE

• Luxembourg EDUcation-Interviews | Creativity and Maker-Spaces | maach3 LTEttelbruck

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!

Science Festival 2017 in Luxembourg (Europe)

.

.

---

.

.

It is the first time that I visited the “Science Festival” in Luxembourg-City, although it is already on its 11th Edition. The first edition was run when Luxembourg-City was Europe’s cultural capital in 1995. This year there was a BIG press coverage and advertising about it so that I decided to go visiting it! I didn’t regret it and I will visit it again, hopefully next year it will not rain again!

.

.

.

WHAT is it about!?

(Start Text from http://chronicle.lu/category/things-to-see-do/biggest-science-festival-returns-to-luxembourg-next-week-with-50-workshops) Organised by the National Museum of Natural History (MNHN) and the National Research Fund (FNR), the purpose of the annual Science Festival is to present and promote science and research in Luxembourg and to encourage young people and the public to become interested in, experiment with and discuss science and technology. (End text…)

Luxembourg needs more people in Science, ICT, Research and through such festivals it tries to use the curiosity of youth to make them sensible to maybe direct them to study in these fields. It was a BIG success as far as I can say, last year they had about 12.000 visitors and more expected for this year. I saw a lot of youth sitting in the different ateliers, workshops to tinker around with lot of interest and motivation. I got told that there were even some kids visiting the place for the second day (Saturday and Sunday, it was open for the public) together with their father and that they spent about four (4) hours, that’s what I call passion! Looks like that there will be some future scientist growing!

Critical Thinking AND Proactive Thinking a MUST in Modern-EDU!

Critical Thinking AND Proactive Thinking a MUST in Modern-EDU! WHY!?

Looks to me as WE will live THE same as in 50’s-60’s with “James DEAN“, Living on the edge Youth & Society“, overload of information!? Change? At that time period it was TV, NOW it’s the internet, similarities? Well, I think so!! A NEW media showed up, the internet, and with the internet ALSO Social-Media. MOST of people are just consumers and DON’T see the dangers NOR do THEY accept THEM!! It’s a Virtual-World which THEY can’t imagine about HOW it will have an impact on Real-World!! BOTH, the Virtual-World and the Real-World are influencing each other!

.

WE are facing actually (2017) “Fake News“, MOST coming and being sponsored by politics interests!!! Just follow “Donald TRUMP’s election campaign and his actually acting…” and YOU will understand WHAT is going on! I encourage YOU to go for “Deep-THINKing” about WHAT is happening in Virtual-World THAT will influence the Real-World!!!

Knowing THIS, you certainly agree with me that there is a MUST to learn about “Critical THINKing, but HOW!?? Please read my curation articles below:

• My Curation about Critical Thinking
• …

 

Read also the article below, please:

Radical Pedagogy: Education has the power to change social inequality by nurturing a generation with an educated mistrust of everything that has been indoctrinated before. This educational stance is one that we must all strive for as the moral purpose of education.

And WHAT about Proactive-Thinking?

Proactive-Thinking SHOULD be burned in into EVERY Educators, Teachers MIND! WHY!??? The MOST IMPORTANT for any education related persons should be THEIR students, learners and the how to to prepare THEM for THEIR future!!

THIS Proactive-Thinking results in getting informed about WHAT is the need from the workforce, industry etc. to make sure that the future workers, employees… will be able to help the country to stay competitive with well educated persons! Especially for NEW jobs who will be created because of ICT, where nearly no one knows WHAT those jobs could be!!

Therefore it is very important that Educators, Teachers focus THEIR Professional Development first on the skills that students, learners need to have!

Read my blog post, below please:

• WHAT Are THE Skills Needed From Students In The Future!?

• …

 

 

 

 

AND as WE are working with ICT, it is MANDATORY that WE will have knowledge about Cyber Security to protect at its BEST OUR students, learners and THAT WE forward OUR knowledge to THEM!

Proactive-Thinking is ALSO a MUST in Makerspaces and MakerEd

To ensure the safety of OUR students, learners, WE MUST be informed about Safety-Rules when working with different tools and the possible dangers of those tools!!

.

.

---

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:
