This board features a SPDT relay that can be controlled directly from the digital output pins on the Arduino or other microcontroller. The relay module has a built-in transistor and clamping diode, and an LED lights up when the relay coil is energized. This is a great and inexpensive way to switch on or off AC or DC loads using your Arduino!
This board is simple to hook up, the 3-Pin male header carries a 5VDC coil voltage and the "on" input signal. An external load is connected via a set of sturdy screw terminals. Terminals are provided for both normally closed and normally open operation.
