Arduino-Python based multiple servo control
This tutorial describes how to control multiple servos with an Arduino module interfaced to a PC through serial port. The application program on the PC is written in Python script that gives control commands to the Arduino module. The Arduino module receives the commands through its serial input and then moves each servo to its commanded position.
The hardware part consists of an Arduino module, four JR Sport ST47 standard servos, and a breadboard to prototype the circuit.
