Relay Shield v3.0
The Relay Shield provides four high-quality relays that can control high current loads to Arduino / Seeeduino boards. It also provides NO (Normally Open) / NC (Normally Closed) interface. It could be a nice solution for controlling devices that could not be directly controlled by Arduinos Digital I/Os. The standardized shield form factor enables a smooth connection with Arduino and compatibles. The shield also has four LED indicators to show the on/off state of each relay.Relays are useful in switching on/off AC appliances like fan, light, motor or high current DC actuators like solenoid valve, etc...If you are interested in finding out more about the Relay, you can check our Arduino Tutorial on How to Control High Voltage Devices with Relay Modules and Types of Relay - Which one should use?NoteExercise caution when dealing with AC.
