Introduction

This project is about a WiFi LED XMAS tree consisting of an ordinary electronics gadget LED christmas tree with a pimped top LED and connected to a WEMOS D1 mini to enable WiFi control.

The hardware

• ordinary LED christmas tree (such as this one from Ali Express [1])
• pimped multi color controllable LED (we used the WS2812B on a small round white circuit board such as one of these [2]
• WEMOS D1 mini based on the ESP8266 (such as this one [3])

•

The code

So far we programmed basic animation for the LEDs and a little webserver to accept commands for turning on and off seperate LED colors.

Find it in on GitHub in our Group

History (reverse orders => latest on top)

• ordered 8 new trees, two are already promised to Tobi
• To make the basic LED animation more smooth, lately we programmed a Chen attractor function but did not finish it properly yet.

Want one for yourself?

• if you can spare roughly 5€ ask me - I just ordered some replenishment trees with

Todo

• Socket for the tree

 * maybe with a display to directly find out about the DNS name and/or IP address

List of known bugs

• yet to come...

Feature requests

• git-secrets to store WiFi credentials in GitHub
• proper encapsulation of animation functions

 * Marijn and I implemented a Chen attractor function to make the transitions more smoothly and random

• more animations for LEDs
• timer function for automatic wakeup/sleep (maybe simply based on time or location and sundown/sunrise?)
• crowd control of multiple trees at once
• put your ideas here...
