This ain’t for the faint of heart, people. you’ll need to know some programming, how to solder, and have some basic common sense so you don’t burn your house down.

Whats needed
Camera slider
Arduino – Uno or nano, or any others (If you’re feeling extra froggy, this can be done with a Raspberry pi.)
Easydriver Stepper motor controller
Arduino IDE
Processing 3 – JAVA IDE
