My playground for RaspberryPi, Arduino, and other microcontrollers. Fritzing diagrams are supplied for most projects. Samples in Python, C++, and C#.

Using the NeoPixel ring, this project creates a multi-mode nightlight to allow someone who needs glasses to tell how long before the alarm will be going off. See more on the wiki or technical details in its README

This uses the Adafruit Feather M0 WiFi, Feather Wing OLED, and BME280 sensor to report to Adafruit's IoT service.

Has samples using NeoPixel ring for a clock or a backlight controlled with pots.

Uses an 8x8 LED grid to display text scrolling in any direction, or animations.

Plus other low-level samples.
