Electronics I – Four-Channel Relay Control

The control of electrical devices and circuits using relays is a fundamental aspect of automation and control systems. Relays act as switches that enable the control of high-power electrical loads with low-power control signals.

In recent years, the integration of Arduino microcontrollers with relays has revolutionized the field of home and industrial automation, providing a flexible and cost-effective solution for controlling various electrical devices.

This project focuses on the development of a system that allows the control of four-channel relays using an Arduino microcontroller powered by 220V AC. The Arduino microcontroller acts as the central hub for controlling the relays and responding to user inputs or external signals. Safety and efficiency were key considerations throughout the design.
