Blueled - Bluetooth LED strip controller

This repo has hardware and firmware for Bluetooth LED strip controller based on atmega328p (the same as in Arduino Nano).

Features:

• Android Application (not started yet)
• Custom colors and gradients
• ~15 different pre-set animation
• Over-The-Air Updates
• Python interface (to control it from PC)
• Save latest state between power on/off
• Up to 100 LEDs on full brightness (WS2812B)

Notes (to refactor)

Be careful with connection between programmer Arduino and target Arduino. I had a lot of corrupted bytes during uploading bootloader/application with ISCP.

Add bluetooth:

$ sudo systemctl start bluetooth
$ sudo bluetoothctl
$ power on
$ scan on
$ # You will see MAC of your HC-05
$ trust <MAC>
$ pair <MAC>
$ # It will ask for pin
$ # That's all!

Load rfcomm kernel module:

sudo modprobe rfcomm 

Create serial port:

sudo rfcomm bind rfcomm0 <MAC>

How to sniff bluetooth: https://github.com/snarlistic/jpnevulator

jpnevulator --tty=/dev/blueled --read --ascii

In case of problems with PC's bluetooth module try:

1. power on/off module through the bluetoothctl session
2. sudo rfkill unblock all
