Relays are great for controlling high-power loads that cannot be driver directly from a microcontroller. This module has onboard 4 Relays to control up to 4 individual loads like - AC Fans, Lights, Motors, Pumps, DC Motors etc. The loads can be turned on by providing 5V at the GPIO pins on an Arduino. The module comes designed as a shield for the UNO which requires no external wiring, or connections between the Arduino and the relay. Simple and Easy plug-and-play operation helps you get started quickly. Great for building industrial automation, home automation & robotics projects.
