WiFi Signal Dial
In this project, we are going to turn the JackBord into a dial so we can visually see the strength of the WiFi signal it is currently receiving. We will use an RC servo, which will move its arm in response to the WiFi strength.
First, we learn how the JackBord measures WiFi strength, and then we learn how to attach a RC servo to the JackBord. We then create our own dial and attach it to the JackBord and the RC servo. Finally, we put it all together by running a program that controls the servo’s arm based on the strength of the WiFi.
