In this small project I will show you how to build a custom ESC/Servo Tester. Along the way I will show you how to setup the timer of the ATmega328P in order to create the required control signal. At the end I will then add tactile switches, a potentiometer and an LCD to adjust the control signal easily. Let's get started!

Step 1: Watch the Video!

The video gives you all the information you need to create your own ESC/Servo Tester. During the next steps though, I will present you some additional information.

Step 2: Order the Components!

Step 3: Build the Circuit!

Here you can find the schematic of the circuit, as well as reference pictures of my finished board.

Step 4: Upload the Code!

Here you can download the code for the ESC Tester, as well as the I2C LCD library which you need to include in your Arduino folder before uploading the code!
