CeilingPixelLamp

Arduino code based rgbw ceiling pixel lamp

Description:

This project is like a disco floor, but on a ceiling, with handmade wooden frames, RGB LEDs and cotton fabric cover as a diffuser. Currently it just supports the usage as RGB Matrix over a USB to Virtual Serial Port connection and can be controlled with software like Glediator (java, cross platform) or Jinx (Windows only).

Modes:

USB 2 Serial:

In this mode, we use the native virtual serial port over USB, provided by the Teensy. You "just" need to send a string over the serial port, starting with a sync character (1-3) and followed by the color values (0-255), based on the pixel order and the chosen sync character:

• sync char, color values
• RGB only:
  • 1,R,G,B,R,G,B,...
• Warm white only (not supported right now)
  • 2,W,W,W,W,...
• RGBWW (not supported right now)
  • 3,R,G,B,W,R,G,B,W,...

Standalone:

In standalone mode, there will be some Templates to chose from, for idle Animations, fixed light presets and so on.

MQTT Server:

still under development...

Hardware:

• Raspberry Pi as Master
• Teensy 3.2
• SK6812 RGBWW Led strip
• 5x 5V 60A (300W) Powersupply

Arduino + CAN Version:

We stopped the development of the Arduino based version, with CAN bus transceiver and WS2812 leds.
That been said, the code provided should still work.

• Hardware:
  • Arduino Nano v3.0 (ATmega328)
  • HC-SR04 Ultrasonic Distance Sensor
  • WS2812B LEDs
  • Warm white LEDs
  • MCP2515 CAN Bus Module Board TJA1050
