4-Axis Servo Control Using Arduino-Python

The project uses an Arduino to control a bank of four independent RC servos with a PC using a USB cable and a modular Arduino-python software stack.

The device can be a great starting point for a motion control system where the movement of the servos is very smooth and they can all be controlled simultaneously and independently. The use of Arduino can provide a lot of versatility and processing power when connected to a personal computer although the platform is ideal for standalone applications.

The creation of a software stack is the primary goal for this project that allows simple and flexible control of multiple servos from any type of Python script. There are two basic components for the solution which includes an Arduino sketch that waits for serial input from a connected PC before moving each servo to its commanded position. The other component is a Python module on the PC that operates the serial connection and formats the data packets expected by the Arduino.

For constructing the circuit, the project consists of an Arduino module, a breadboard, and four standard servos with three wires each including Ground, Power, and Control.
