If you want to build advanced things like internet-connected gadgets and more, you need to use a microcontroller.
The easiest way to get started with microcontrollers is using the Arduino.
I’ve created a course, Getting Started With Arduino, that you can find here:
I got some feedback that it was hard to read the code from the videos. So, I just updated the course with downloadable code for each lesson.
You can find the code under the video in each lesson.
Keep On Soldering!
