An Arduino project for turning on/off a relay at a scheduled time. The project uses the Adafruit Feather and a real-time clock to ensure accuracy. This project is essentially a hand-made version of ...

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 ...

IN - This pin is also called the control pin because it is used to control the output of the relay. COM - is connected to the device you intend to connect. NC - terminal is connected to the COM ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

Abstract: Purpose work says about the capability of displaying information, and describes the methods of constructing a circuit needed to obtain such device. But Sending and monitoring various notices ...
