Package Included:1*12V Eight 2 Channel Relay Module For PIC AVR DSP ARM Arduino 2 CH Optocoupler(Black) This is a 2 Channel 12V Relay interface board, Be able to control various appliances, and other equipments with large current. 12V, so the relay module JD-Vcc is connect to Arduino Vin to supply the 12V for the relay coils. Send to a. In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan. Discussion in 'Power Electronics' started by Mike197714, Apr 11, 2018. The coil terminals of the relay are connected to the supply with a push switch. 5V Power supply. This is a 5V 4-Channel Relay interface board. Can separate the power supply. Arduino Stack Exchange is a question and answer site for developers of open-source hardware and software that is compatible with Arduino.
