In this lesson we take you through step-by-step instructions on creating a remotely controlled RGB LED. This is the solution to the Homework Assignment given in Tutorial 68. It is important for you to try and complete this on your own before looking at my solutions.
We are building this with parts from our Elegoo Kit , and our actual build is using an Arduino Nano, which allows the project to be built on a single breadboard. You can get the neat jumper wires HERE.
This video steps you through our build.
Below is the code we developed in this video.
