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.

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:

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!!

Servo Motor Position displayed on 0.96 inch 128X64 I2C OLED

 

 

WE were playing around already with OLED displays in previous tutorials <===> https://gustmees.wordpress.com/?s=oled <===> where WE created an Analog-Digital Clock a Temperature/Humidity Monitor with “Heat-Index” and Text messages on the OLED. In this tutorial WE will display the angle of  a rotating Servo-Motor on an OLED.

This is actually very easy and WE will learn also (for those who want so…) the different coding for OLEDs here below:

• https://github.com/olikraus/u8g2/wiki/u8g2reference#drawbitmap
• …

.

Temperature & Humidity monitor using Arduino NANO + DHT22 + 0.96 inch 128X64 I2C OLED

WE were playing around a lot already with I2C-LCD displays <===> https://gustmees.wordpress.com/?s=i2c+lcd <===> but not yet with I2C-OLEDs. In this tutorial WE will create a <===> Temperature & Humidity monitor using Arduino NANO + DHT22 + 0.96 inch 128X64 I2C OLED <===> which displays the temperature in °F AND °C, as well as it displays the “Heat Index“.

FIRST of all, let us talk about the “Heat Index“, what it is and WHY it could be important to display it:

• Kestrel Heat Index Reference Guide Celsius
• WHAT is the Heat Index? (in °F)

.

Heat-Index in °C

NO more Theory now, the PracTICE!

Let us have a look on the wiring and check the below Fritzing, please. It shows a DHT11 Sensor instead of a DHT22 Sensor, but the wiring is the same. It shows ALSO a 220 Ohm resistor instead of a 10K resistor!! Use a 10K resistor please!!

.

.

Once finished the wiring, WE will need to go for the coding by using a Sketch, we will use a already done Sketch, which WE can transform to our needs from:

• https://arduino-er.blogspot.com/2015/05/temperature-humidity-monitor-using.html
• …

IF you use “°Fahrenheit” you can use it without any changes, but IF you use “°Celsius” in your country WE will need to make some changes in the code, which WE will discuss the How-To here below.

First step: you can change the text, IF wanted: Original says "DHTxx test!", I changed it to what you see below; GET creative ;)

.

 

Click image, please, to enlarge

EASTER Egg with NeoPixels WS2812B made from cardboard

.

.

Soon there will be EASTER 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 EASTER-EGG 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 Easter-Decoration, e.g. an egg. 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.

I copied an image (the orange egg) from an Easter-Egg which I found on the internet (license-free), glued it on the cardboard and cut it 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 Neopixels LEDs strips, you need to follow the arrows on the strips to connect each of the LED strips, thus meaning: see PICs please:

.

.

Once all the 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 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 😉

And here the MOST important to make it work, the code:

• NEOPIXEL-WS2812B-60-ARDUINO-CODE
• …

The code will get downloaded and copy it, then paste it into the Arduino IDE.

.

This is how the code will look and where you can (MUST) modify it, see PIC below please:

.

.

You need ALSO to download and to install the “FastLED.h” Library

Click image, please, to enlarge it.

.

Download the  “FastLED.h” Library here in case of that you will NOT find it in the “Library manager”:

• http://fastled.io/

How-To transform an LCD1602 SPI Sketch to an LCD1602 I2C Sketch

We were already playing around, as seen on my tutorials below, with the Temperature/Humidity sensors DHT11, DHT22 and LCD1602, without I2C possibility. There were a lot of cables to connect, we will try out this time to use a LCD with I2C bus connection as it uses ONLY 4 wires to connect. It’s a perfect project for newbies in coding as they will see the measured values directly on the LCD screen, the success and happy factor is guaranteed!

  • Check out the above tutorial to find out about the cabling, this one with I2C is much less cabling (wiring)! 😉

Let us have first a look on the wiring (cabling) which is actually very easy, have a look below please:

.

====> Click image, please, to enlarge.

The wiring (cabling) will take about +/- 5-10 minutes depending on your own rhythm… Let us have a look on the coding now: we will use exactly the same code (Sketch) as in our first tutorial here, which we will change just a bit to fit for I2C LCD1602 display:

• https://howtomechatronics.com/tutorials/arduino/dht11-dht22-sensors-temperature-and-humidity-tutorial-using-arduino/
• …

Copy&Paste the code from above tutorial where it is marked “I also made an example where I display the results on a LCD. Here’s the source code of that example:” and paste it into the Arduino IDE. Connect the Arduino NANO with your computer now. Open the Arduino IDE and choose the board “Arduino NANO”, see screenshot below, please:

Click image, please, to enlarge.

.

Next step, on the same Arduino IDE select the Processor:

.

Click image, please, to enlarge.

.

TIP: when the LED on the Arduino NANO is lightning GREEN it is an original NANO and you must choose “Atmega328P”; if the LED is lightning RED, it is a clone and you must choose “Atmega328P (Old Bootloader)”.

.

NOW it is about time to adapt the code (Sketch) to an I2C-LCD1602 display, let us have a look on the Sketch (the original):

.

Click image, please, to enlarge.

.

As we can see in line 10: the library is meant for a normal LCD display, it needs to get changed for a “I2C LCD Library”.

In line 15: the same it shows the wiring pins for a normal LCD display, it needs to get changed for a “I2C LCD” display.

In line19: It is BETTER to add as well the I2C-Address, mostly “0x27” OR “0x3F”.

That is NOT much to change, we will see in the screenshot below the How-To:

.

Click image please, to enlarge.

.

By enlarging (click on the image) you will see by comparing where the changes are. I commented in the lines the WHY… Try it out to change it yourselves or just download the Sketch (Code) here below who is working:

• LCD1602-I2C-DHT11-Temp-Humidity
• …

Copy&Paste this code into a NEW Sketch on the Arduino IDE and upload now the code to the Arduino NANO (or Arduino UNO) and enjoy it!

.

Stay tuned for next blog post(s) 😉
