WS2812-Strip controlled by Perl via ESP8266

Small project to control a WS2812B-Matrix/Strip via Network.

Prerequisites:

• Microcontroller:
  • Arduino 1.8. IDE
  • ESP8266 Arduino Add-on - https://github.com/esp8266/Arduino
  • WS2812-I2C Library included (taken from https://github.com/scottlawsonbc/audio-reactive-led-strip )
• Host
  • Perl
  • IO::Socket::INET

Change hostname (currently "trixel") to IP which is shown on Serial after WiFi-Connect in the Perl-Script, if you don't own a DHCP-Server which respects DHCP-Hostnames advertised by Clients

Protocol:

I decided to implement a new protocol (OpenPixelControl was the template - but it didn't fit here). It's quite simple:

• UDP via Port 7777
• 5 Chars per LED

1. Number of LED (0 is start)
2. Mode (0 for RGB-Set, 1 for HSV Set)
3. R or H
4. G or S
5. B or V

• Packets must be 1400 Bytes long (fill rest with 0x00)
