On top of driving LED strips, Spark and Pixel are designed to be modified, reprogrammed, and played with! Their USB interfaces enable easy programming via the Arduino interface.

Arduino microcontrollers have added Python to the range of compatible programming languages. Others can be used, and not just Arduino's own IDE app.

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

The board has four LED arrays resulting in a display of 8×32 LEDs. The MAX7219 takes a 16-bit data word over a 10 MHz serial bus, so programming is pretty easy.

To actually power and control the entire circuit, [Martyn] used an Arduino loaded up with a program based LedControl library makes programming the spedometer a snap.

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 ...

6. Upload this code. Tip: Once you’re done programming the Arduino, leave the lights on. It’ll make it easier to attach the strand to the sweater since you’ll be able to see the thread ...
