Description
Electronic brick of relay can be connected to digital I/O port, when the input of S port is low level, relay will be under disconnect state; when the input of S port is high level, relay will be under connect state. It can be connected in series to the LED lights, buzzer or even the loop of a small lamp so as to control the state of the switch.
