[Thomas] wanted to play around with a few high-power LEDs and a RaspberryPi. LED controllers usually require some form of PWM to change the brightness of a LED, and unfortunately the Pi only has one ...

At first glance, using a microcontroller for a simple fancy light project is overkill. However, the existing design can be modified later without additional hardware. Often a few extra code lines will ...

Userspace Raspberry Pi library for controlling WS281X LEDs. This includes WS2812 and SK6812RGB RGB LEDs Preliminary support is now included for SK6812RGBW LEDs (yes, RGB + W) The LEDs can be ...

The Pi Zero is a great piece of hardware, even if you’re not designing another USB hub for it. [Marcel] wanted to control a few RGB LED strips from his phone, and while there are a lot of fancy ways ...

Imagine being able to check up on your Raspberry Pi from anywhere in the world using a simple web interface. With PiCockpit, you can monitor your Raspberry Pi, control GPIO pins and run health tests.
