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 ...

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v ...

[Kenneth Finnegan] quenches our clock-a-day compulsion with his Arduino based binary timepiece. The clock uses a 5×7 LED matrix as a display and shows month, day, and time. He sourced a DS3232 ...

Abstract: Relay protection and emergency automation systems serve as automatic safeguards against damage and abnormal operating conditions in electrical components of power grids. They constitute a ...
