This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

Arduino sensor projects blend coding with tangible results, making learning interactive, practical, and fun. From simple LED triggers to multi-sensor systems, these builds teach real-world electronics ...

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 a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Want to control the colors in your home? Sure, you could just buy a Philips Hue bulb, but where’s the hacking fun in that? [Dario] agrees: he has written a tutorial on building an Arduino-controlled ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...
