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 ...

Let's use Arduino to make a light that turns on automatically only when someone approaches and turns off after a while.This time, we will use a PIR motion sensor that detects changes in infrared rays ...

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 ...

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...

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 ...

Explore two new Elektor Academy Pro STM32 programming courses, featuring MicroPython and Arduino, as part of the Embedded ...

If you searching for an LED matrix for your next project or to add to an existing application you may be interested to know that the Maker LED Display is now available to purchase from the Crowd ...

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 ...
