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 ...

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 ...

The Arduino Wire library is a core aspect of Arduino's integrated development environment, or IDE, and is a must-have if you're using sensors or extra microcontrollers in your project. Like ...

Otherwise, simply connect Arduino 5V and Gnd, and leave VCC to JD-VCC jumper in place. Additionally, each relay in this module has one NC ... The next crucial thing is the Nichrome wire to make the ...

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 ...
