Besides we are using 12v relay in this project. Vin pin of Arduino cannot easily supply this much current for both relay. Hence transistors are used to conduct current from Vin pin of Arduino to relay ...

Simplistic relay controller made using arduino. Activation of relay is decided by pressing the push button or sensor readings (in this module sensors are replaced with another push buttons). To ...

Well, what is the use of a relay that provides the operating system for the push-button start and handles devices with high voltages up to 220V? Through the relay, a bulb or any electronic device can ...

You can use any standard 9V battery to power the whole circuit, and the Push-ON (push ‘n’ hold) switch (S1) to activate the alarm function. An additional Electro-Magnetic Relay (EMR) is also attached ...

So as of now we understand what is a relay and why they are used in the circuits. Next we will take a simple example where we will be turning on an AC lamp (CFL) by using a relay switch. In this relay ...

[Lars] shows you how to get a perfect score on the first four levels of BIT.TRIP RUNNER by using an Arduino to time and send button presses. This is a pretty simple game that uses a couple of butto… ...

[Ed] was tasked with adding push-button degaussing to an arcade cabinet’s CRT console. The display can be rotated to portrait mode for games that require it, but each time this is done, the m… ...

1. Press Lock/Unlock on key fob → Powers up the Arduino via timer relay for 40s. 2. Hold Lock Button for 5 seconds → Sends a fake “press” to the push start button module - Ignition turns on. 3.
