Raspberry Pi: Control Relay switch via GPIO

WebFeb 16, 2024 · A Relay is an electrically operated switch. The 12 Volts that the Solenoid requires to operate would fry the Raspberry Pi if directly connected to that voltage. This is because the maximum voltage a Raspberry Pi microprocessor can take is 5 Volts. Thus we can use the Relay to prevent this and allow a passageway for communication. WebFeb 18, 2024 · Notice that the Vin of the relay module is connected to the 3.3V Pin of the Pi instead of the 5V Pin. This is because the voltage level for a digital HIGH (1) state in the raspberry Pi is 3.3V as opposed to the 5V of the Arduino. A digital LOW (0) signal is use to trigger ON the relay while a digital HIGH (1) signal is used to trigger OFF the ...
