Arduino Code for the robotic arm using Arduino Programmable robot arm with the 4 Degrees of Freedom robot arm. The robot arm will have two basic functions. The first is servo position record (each record is for a "step") and the other to play the recorded positions. It can record and play 8 positions using 4 potentiometers and 2 buttons. (But you can add as many as you want). Also, an OLED display has been added for you to view each position while you are recording.
