A simple and convenient way to interface 2 relays for switching application in your project. This relay driver boosts the input impedance with a regular BC547 NPN transistor (or equivalent). Very ...
In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...
The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for ...
If you’re at all familiar with digital computing, you’ll know that computers represent everything in binary values of one and zero. Except that’s not technically the only way to do computing! You can ...
Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...
