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 ...

All four relays are connected with Arduino at 8,9,10 and 11th pins (In1, In2, In3, and In4), and 1 12v adapter is used for powering the circuit. We have connected 220VAC bulb at the terminal block of ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

The board can be programmed with the Arduino IDE or PlatformIO, and LilyGo provides instructions and code samples to control the relays through the Blynk IoT platform or a web server, as well as a ...
