Summary

This circuit is designed to control a system that includes two bipolar stepper motors, multiple limit switches, a hall sensor, an IR transmitter and receiver pair, and a linear actuator. The central control unit for this system is an Arduino Mega 2560, which interfaces with the various components to manage their operation. The stepper motors are driven by dedicated stepper drivers, and the limit switches provide positional feedback. The hall sensor is used for detecting magnetic fields, while the IR components enable wireless data transmission. A relay module is used to control the power to the linear actuator. The entire system is powered by a 12V 5A power supply.
