Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Regular candles can be awfully boring at times. They can only produce one color and the flicker is so… predictable. They can’t even be controlled by an infrared remote control, not to mention the ...

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

One of the first projects that most people do on an Arduino is to light up or flash an LED. It seems ultra-simple because it ...

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 ...

Makers, developers and hobbyists that enjoy creating projects using the Arduino platform may be interested in a new Arduino prototyping tool in the form of the Lumioto. The Lumioto has been created by ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

Discover how the Arduino Opta Pro can be leveraged beyond its industrial roots for smart home and DIY automation. In my article, I share hands‑on insights, practical code examples, and hardware ...

In the last installment of The GeekDad Arduino Guide, I introduced you to the Arduino hardware and why it is so cool. Now, let’s start actually using an Arduino. How do you get started? Well, first ...

A rduino boards are a popular choice for DIY electronics, but it's not always clear how to get started with building projects and programming. There's now one more solution to that problem: a new ...
