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 ...

// RTC board: Adafruit Adalogger FeatherWing Real time clock + SD card for data reading & writing //hardware configuration, and physical location. //The Analog pin the relay is connected to. This ...

The DS3231 RTC module is a real-time clock that uses less power and has highly accurate communication via an I2C interface. Also, the DS3231 real time clock has its temperature-compensated crystal ...

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 ...

I have an old window AC in my lab, which is at the terrace. The AC needs to be run intermittently, especially when I am out of station and the lab PC needs to be kept cool during noon time when the ...

With this project, I conclude my presentation of Basic for Arduino. Unless you have any further requests, I will take a break. Please let me know if you enjoyed using Great Cow Basic. Best regards ...

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 ...
