This Arduino sketch sequentially turns on and off LED strips that are attached under the bullnose of each step in a stairwell. The project uses synchronous serial communication with 74HC595 shift ...

And here is what the actual HC-06 Bluetooth module looks like: This design scheme is suitable for LED stripes consisting of 30 or fewer LEDs. The reason for that is power consumption. One WS2812B LED ...

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 ...

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 ...

[Alan] was commissioned to make some wearable, radio-controlled LED strips for the Travelling Light Circus. It has taken some time, but he has recently finished some prototypes, and thought it was a ...

When we are talking about the MAX7219-based dot matrix display module, it consists of 64 LEDs connected in a row-column format so that we could easily control them with the multiplexing technique.

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 ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...

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 ...
