ESP8266 Based LED light strip controller via a web browser
Simulates an LED strip and allows very NeoPixel-like access
NeoPixels! but easier. Beginner friendly functions to control Adafruit NeoPixels, using as simple syntax as possible.
A project that uses the nRF52 to control a neopixel (ws2812b) over BLE using a custom mobile app built using the ionic framework.
This open source application takes P5 code and visualizes/outputs it to various professional and hobbyist lighting units, making creating light shows easy and accessible.

Catatumbo is an Adaptive Smart Home Lightning project that lets your home indicate information of relevance for you. It aims to build up light components (led strips) that are distributed across the appartement. Each device being addressed via network or KNX in the future. While each device can foresee a different scene, in special cases they can also act together - e.g. for indicating an alarm situation in the whole appartment. Special focus is on adaptive lightning scenes which indicate real world information via color codes - e.g. stock prices, weather forecasts, social media states. Just by having your hall stand illuminated in bright blue may indicate that you better take the umbrella along. Let yourself be dragged into the fascination of Catatumbo - Happy weather watching!
Arduino Library for RainbowBit - Serial RGB LED
My approach is using a SPI to collect 24-RGBs-Strips-Data and a SYNC from a impeded SoC. Another approach I came up with is to reuse the Adafruit-Neopixel-Library. I attached my FPGA_NeoPixel.h file. Technically it inherits from Adafruit_NeoPixel and overwrites the void show() with SPI-Code so you are able to use the methods from Adafruit_Neopixel to set leds or calculate color spaces. I have tested it on an Arduiono-Nano but it is easy to port the Libs to other SoCs.

MiniAutoKeyboard is a CircuitPython script designed for the Adafruit Rotary Trinkey with the ATSAMD21E18 32-bit Cortex M0+ SoC. The rotary encoder can be used to select a numbered *.txt file on the CircuitPython USB flashdrive of the Trinkey and output them as a regular USB HID device (e.g. a keyboard).
Upon moving into my home and realizing that the pantry has no light. As a programmer, I leaped into action and created and automated light, so you wouldn't have to remember if the pantry light has been left on or not.
