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:

The Code (Sketch)

There is an already existing sketch existing which WE will use, please use the link below to download the code:

The tutorial where the Sketch (Code) is located is in German, BUT that shouldn’t be a problem 😉

For those who want to experiment a bit around with OLEDs, here my recommendation with ready codes and very well explained tutorials:

The libraries

You might need to add certain libraries, see below please which ones will GET needed, please.

IF a newbie, please check the below tutorial for the How-To:

The Wiring

Click the image, please, to access the source of the image and tutorials.

TIP

Fix the Servo-Motor on cardboard or on a wooden, plastic, plate. Glue a white paper on it and mark the angles on the paper. This would be a nice project for schools 😉

Play around with the code to add some more angles ===> LEARNing-By-Doing 😉

First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Ultrasonic Radar

Maker, MakerED, Coding | Ultrasonic Radar

On previous blog post I discovered “Processing Software” and I was such impressed about hat I was looking to find some other Coding tutorials with Arduino which use it; so I discovered this one using an Ultrasonic Sensor (HC-SR04) and a servo motor. As I had bought already a “Sensor-Kit“, please check my blog post, First Steps with the Arduino-UNO | Maker, MakerED, Coding | Sensor-Kit SKA-36 so I have the necessary parts…

Please check the video tutorial below, to find out about yourselves about what incredible is possible.

You will remark that there is only a provisionally fixing of the “Ultrasonic Sensor” (HC-SR04); there one can do better! So, I had a look on Amazon to find a “Pan & Tilt Kit“, here it is:

As I didn’t know how to make the assembling, I was looking on YouTube and I found this video tutorial which helped me a lot, please check below.

The assembling wasn’t that difficult actually, a bit puzzle around with tiny screws and juggling… The “Pan & Tilt Kit” is delivered with two (2) servo motors which will get fixed, but we need only one of them for our project. Once everything assembled we fix the “Ultrasonic Sensor” with hot-glue on the top of the “Pan & Tilt” socket like shown on the images below.

SO, we have made the mechanical part, the most difficult in this project… Let us go now for the wiring, check the wiring schema below, please.

It doesn’t look that difficult, isn’t it 😉 SO, once finished we will have a look on the code, “Copy & Paste” it and upload it into the Arduino IDE. Please check the tutorial here step by step for the how to ===> https://howtomechatronics.com/projects/arduino-radar-project/

In the above mentioned tutorial we have the codes for the Arduino, as well as for the Processing software. For those who haven’t yet installed the software, here a reminder for download:

Once uploaded both codes you will be astonished about what is possible with coding and maker 😉 Have fun and stay tuned for next projects…

Advice for EDUcators, Teachers:

Using Coding, MakerED is THE perfect way to GET Students, LEARNers interested for Maths, Physics (e.g.) by using THEIR hands in Practice for understanding while guided by a (two, three…) Coach(es) ===> LEARNing-By-Doing and Team-TEACHing with FUN.

The author was also a winner of an electronics contest (Germanic countries) in 1979 and got his project published in the “Electronics Magazine ELO”.

Stay tuned for next blog post(s) 😉..
