Pet project using raspberry pi picos to control led strip lamps

I Love Lamp

A pet project for creating a programmable LED strip of 60 LEDs in a vertial lamp.

Raspberry Pi Picos are used to controll the light strips. They are a thin client that receives a stream of led color values. This project includes a Node server that is the lighting engine, and communicates with the Picos. It can also accept commands from a Web client.

Using:

• Raspbery Pi Pico
• SK6812 RGBW LED strip

TODO:

• Update tests in engine from vitest since it's isn't in the vite project anymore
• Env variables for the PI and server to listen on the ips/ports I need them to

Demo Video

// Soon.

Color Engine

The engine directory contains the engine to caculate what colors to send to the microcontroller. It's a layer based system using generator functions to calculate the next 'tick' or frame.

TODO:

• Give generater functions the actual time since last tick to mainatin better timing if there are network slowdowns or hickups.

Pi

This pi directory holds the micropython code to build a UDP client to recieve LED colors as byte data and to push it to the LED strip.

The client is very thin ATM, only taking in a byte array of LED colors to push to the LED strip. Future iterations might include having the color engine run locally, so one doesn't need a server to render animations. My inital venture into MicroPython made this difficult to achieve with desired performance.

Server

This is the server for that pushs UDP packages to the microcontrollers.
