Description: Using an Arduino or a micro controller, we can generate cool-looking patterns with an led strip containing addressable LEDs. In this case, I'm using an Arduino uno (clone board) and a ...

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 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 ...

[Rockwell] sent us an update on his traffic light hacking. Dedicated readers will remember seeing this legally attained traffic signal controlled through a parallel port from back in 2005. The new ...

The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for ...
