A smart relay for the Arduino that allows programming of 10 time based alarms and one voltage based alarm (for overvoltage/ under voltage protection). Also uses DS1307 RTC to keep time, and allows the ...

It detects potential welded conditions and provides status updates through the serial monitor. Ideal for learning about relay management and timing functions, this project is built using Tinkercad for ...

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 ...

This project is meant to control electrical appliances like fans and lights. You can configure two Yoda modules, one as receiver and the other as transmitter, to control relays that switch on fans and ...

This Device Controller project based on an 8-bit ATmega328P microcontroller (MCU) can control up to eight devices connected to its electromagnetic relays. The article also describes how to program an ...
