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 ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

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 ...

A rduino boards are a popular choice for DIY electronics, but it's not always clear how to get started with building projects ...

[Credit: Djandco on Instructables] The Look of Disapproval (made using the unicode character for the letter “tha” in the Indian language of Kannada and an underscore) is possibly my favorite ...

This 8x8x8 LED cube with 512 LEDs takes the old 3x3x3 light cube made up of 27 LEDs to the nth degree. This, certainly more time consuming project, actually involves a simpler design. By using a ...

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 ...

As mentioned in LED Lightlane increases bicycle safety at night we like combinations of LEDs and bicycling on Gadget Master... Here is another example, drawn to our attention by Electronics Weekly's ...
