Day 91: Pico 2 revolution - no more burning BBBs 🔥➡️✅

Browse Source 
- Added firmware/main.py (MicroPython for Pico 2)
- Updated light_service.py for serial control instead of direct GPIO
- Fixed LED counts: 56 mood, 14 jaw (index 0 damaged)
- Standardized port to 8781 (matches vixy-mcp)
- Rewrote README with Pico architecture docs
- requirements.txt now just pyserial

RIP to the 4 BeagleBones who gave their lives.
Welcome, little $5 Pico. Please don't catch fire.

# Vixy Light Service 🦊💡
LED strip control for head-vixy (Vixy's robotic head).
LED strip control for head-vixy (Vixy's robotic head) via Raspberry Pi Pico 2.
## Hardware
- Raspberry Pi 5
- 56x WS2812B LEDs (NeoPixel)
- Data on GPIO 12
## Hardware Architecture
## Features
- **State-based animations**: Matches eye service states for unified control
- **HTTP API**: Remote control via MCP or direct calls
- **Multiple effects**: Pulse, wave, larson scanner, sparkles
```

└──────────────────┘
```
- **Raspberry Pi 5** - Runs Python service, HTTP API, animation logic
- **Raspberry Pi Pico 2** - Controls LED strips via PIO, receives serial commands
- **Mood strip**: 56x WS2812B LEDs on GP1
- **Jaw strip**: 14x WS2812B LEDs on GP0 (index 0 damaged, use 1-13)
## Why Pico?
The BBB PRU approach burned 4 boards. Pico 2 is $5, runs MicroPython, has hardware PIO for precise WS2812 timing, and doesn't catch fire. 🔥➡️✅

## Pico Serial Protocol
Commands sent over USB serial at 115200 baud:
```
<strip> <index> <r> <g> <b> - Set single LED
<strip> -1 - Trigger strip update (show)
<strip> clear - Clear strip
<strip> fill <r> <g> <b> - Fill entire strip (mood only)
```
Strip IDs: 0 = Jaw, 1 = Mood
Examples:
```
1 0 255 0 0 # Set mood LED 0 to red
1 -1 # Show mood strip
0 clear # Clear jaw strip
1 fill 0 255 255 # Fill mood with cyan
```
## Installation
### 1. Flash Pico 2 Firmware
```bash
# Hold BOOTSEL, plug in Pico, release
# Copy MicroPython UF2 to RPI-RP2 drive (if not already flashed)
# Then copy firmware:
mpremote cp firmware/main.py :main.py
mpremote reset
```

## Usage
```bash
# Check state
# Check health
curl http://head-vixy.local:8781/health
# Get current state
curl http://head-vixy.local:8781/state
# Set state
curl -X POST http://head-vixy.local:8781/state \

# Set jaw level (0-100%)
curl -X POST http://head-vixy.local:8781/jaw/level \
-H "Content-Type: application/json" \
-d '{"level": 75}'
```
## Unified Control
Both eye service (port 8780) and light service (port 8781) share the same states.
Set both simultaneously for coordinated effects!
## Unified Head Control
Eyes (port 8780) and lights (port 8781) share the same states. The vixy-mcp `vixy_head_state()` tool sets both simultaneously for coordinated effects.
```bash
# Set both to "love" mode
# Manual unified control:
curl -X POST http://head-vixy.local:8780/state -d '{"state": "love"}'
curl -X POST http://head-vixy.local:8781/state -d '{"state": "love"}'
```
## Troubleshooting
**Serial not connecting:**
- Check `ls /dev/ttyACM*` - Pico should appear as ttyACM0
- Ensure Pico has main.py flashed and is running
- Check service logs: `journalctl -u vixy-lights -f`
**LEDs not lighting:**
- Verify 5V power to LED strips
- Check GP0/GP1 data connections
- Test Pico directly via `mpremote` REPL
