This section will show you how to switch AC outlets using a Four Outlet Power Relay Module. You can also use this method to control any device that looks for 5V logic (such as an Arduino input).
The RFID WIZ has a white JST PH (2mm pitch) jack with 2 pins
- GND - always stays at 0V
- SIG - switches from 0V to 5V when the relay flips
A 2-pin JST cable is included with your kit, and can be used to connect to any device looking for a 5V logic input.
The power relay module has corresponding inputs:
