In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board ... You can use this code example to introduce a delay in your circuit. The variable “stayON” is used ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

Impulse relay turns on with an electrical impulse at the control input and turns off again with another impulse.

Project using Arduino UNO and a RFID reader module (EM-18) to control an LED and a Relay. Circuit schematic and Arduino Sketch (source code) are provided here. The reader transmits radio frequency ...

Whenever a valid key is swiped, the Arduino triggers a relay which can then be used to control just about anything ... user to select how long the relay circuit should remain open.

All it does is time the activation of the relays that control the gas flow, power, and wire feeder, so [Brett] decided to use an Arduino instead. The welders control circuit runs at 24V ...

So you finally decided to hop on the Arduino bandwagon and start making electronic projects as a fun hobby. As a beginner getting started with Arduino, your first instinct is typically to buy a ...
