Description: A relay shield is an additional board designed to be attached to an Arduino board, allowing for easy and efficient control of multiple relays. These relays are electromechanical switches that enable the turning on or off of high-power electrical devices, such as lights, motors, or appliances, using low-voltage signals from the Arduino. Relay shields typically include several relays that can be controlled individually through the Arduino’s digital pins. Additionally, they often feature protection circuits to prevent damage to the main board and facilitate the connection of external devices. The ease of use and the ability to control high-power devices make relay shields popular components in home automation projects, robotics, and industrial control systems. Their modular design allows for quick and effective integration into various electronic projects, making them a valuable tool for both beginners and experts in programming and electronics.
