“Arduino Self-Timer” project presented here is a low-component count 60 seconds countdown timer. It can be powered from a 9V compact battery or suitable Arduino AC mains adaptor. Working of the ...

One of the common use cases for our Arduino Relay Controller is setting up a yard or staging ladder. An Arduino relay is often used to control power on tracks by steering or simply turning power on or ...

Simple non-blocking timer library for calling functions in / at / every specified units of time. Supports millis, micros, time rollover, and compile-time configurable number of timers. This library ...

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 ...
