This project is under heavy development, not suitable for use beyond tinker at the moment
- Create an automated system where LEDs can be synced to music
- This system must have the following requirements...
- Any arbitrary song can be played
- Limited user interaction (preferrably all 'client' side)
- Any song can also be pre-programmed using a set number of sequences
- Has multiple sequences that can be turned on without the need for music
- Can map the LEDs in different patterns depending on their physical shape/pattern
- LED Strip(s) (WS2811)
- Arduino UNO
- FastLED
- Raspberry Pi (3rd gen) (communicating to the arduino through serial)
- RPi -> Arduino LED protocol
- Client (the device playing the music) (my MacBook Pro for now)
- Some sort of sync handshake between the client and raspberry pi
- Specific hardware dependence
- Potentially messy standup
- Songs need to be manually pre-programmed before the system can run through them
- ...
- The RPi does not do well playing music in general
- Headphone jack seems to have very poor output (without any additional shields)
- One problem was a lot of white-noise, I fixed some (not all) of those issues here:
- Built in music player (
omxplayer example.mp3) played music slowly - Python specific music player (
pygame mixer) output the following errorspygame.error: No available audio deviceHome directory not accessible: Permission denied- I made no progress with either of these issues
- Albeit, it's likely I've messed with some configuration that caused these issues
- Headphone jack seems to have very poor output (without any additional shields)
