Fancy Lights

Raspberry Pi IKEA Dioder Light Controller

A lockdown project.

Features ( Current and TODO)

• Can control light colour
• Simple Web Interface
• Light transitions / animations
• Real time control
• Alexa Integration

---

Usage

Once installed on a Raspberry Pi, the control panel can be accessed at the IP of the Pi or, more conviniently, http://nerves.local

---

Uses the Elixir Nerves framework to create a firmware for the Raspberry Pi, and uses Pigpio to generate PWM signals to control the LED Lights.

Pi connected to the DIODER controller using these modifications. Soldering required.

Uses a Pheonix web interface to control the lights currently. Will implement using Liveview later, the current interface is the bare minimum to be controlable as doesn't work completely.

Install

A Nerves 'poncho' project. Requires Elixir and Erlang to be installed.

Firmware for the Raspberry Pi Zero can be downloaded here

To generate your own firmware:

git clone https://github.com/th0mas/Fancy-Lights
cd Fancy-Lights/fancy_lights_firmware
export MIX_TARGET=<Your Decvice Tag> # View supported devices
mix deps.get
mix firmware
mix firmware.burn # burn firmware to inserted SD Card

Suported Devices

Tested on a Raspberry Pi 0, should run on any Nerves supported raspberry pi.

Notes

Probaly not the most idiomatic Elixir code, this is my first Elixir project, it does, however, work. Works on my Raspberry Pi Zero W.
