Level up your Arduino LED skills fast
From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...
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 second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is ...
