14+ Relay Module Schematic. For better understanding let's see the circuit schematics of the relay module in this configuration. Pn532 nfc rfid module — a quick.
The arduino can be programmed to turn on the relay when a certain event occurs, for example when the temperature of a thermistor gets higher than 30°c. Relay module 1 relay, 5v, 30a. That's where the relay module comes in.
