Arduino Nano Controlled IR Beam Break Detection with Ethernet Connectivity

Circuit Documentation

Summary

This circuit is designed to interface an Arduino Nano with an IR Beam Sensor pair (transmitter and receiver), a DC worm gear motor, a 2-Channel Relay module, a Module Ethernet W5500 for network connectivity, and a couple of micro switches. The circuit is powered by a Switching Power Supply, which is regulated down to the required voltage for the Arduino Nano using a Buck converter. The IR Beam Sensor is used to detect objects passing through the beam, and the micro switches are likely used as limit switches. The DC motor is controlled via the relay module, which is in turn controlled by the Arduino Nano. The Ethernet module allows the Arduino to communicate over a network.
