rayn2k18 / pc_light_controler Goto Github PK

Aims :

• control RGB lights from my computer case (rgb lights are basically ws2812b on 5v led strips)
• trigger animation from hdd led activity or audio output
• remember my settings :
  • which animation to trigger at start,
  • on external trigger
  • animation speed
  • trigger level (for audio)
  • brightness
• power on / power off my PC (since wake on lan doesn't work on my MB)

Needed components :

• 1x ESP8266 (in my case : lolin v3)
• 1x PCB (schema on kicad directory)
• 6x 470ohms resistors
• 3x DIP-4 817C Optocouplers
• 2x 4 pins connectors (1 pin is to be removed)
• 6x 2 pins connectors
• 1x jack 3.5 connector (audio trigger IN)

Needed librairies :

• ESP8266WiFi
• ESP8266WebServer
• WS2812FX (code based on "esp8266_webinterface" example files from that library)
• EEPROM

Control URLs (GET) :

http://<@IP of ESP>/set?<command1>&<command2>&<command3>...

• power_bton=1 : trigger power button for 600ms (power on / off / sleep computer)
• power_bton=9 : trigger power button for 32s (force power off computer)
• on : starts animation
• off : power off leds
• reset : restarts ESP
• trig_mode=0 : trigger mode disabled
• trig_mode=1 : HDD led triggers animation
• trig_mode=2 : audio level triggers animation (default)
• trig=1 : triggers the "random fireworks" animation
• trig : triggers the current animation
• m=<0-56/59> : switch to animation (see http://<IP of ESP>/ for numbers)
• b=<0-255> : sets brightness
• s=<number> : sets animation speed
• c=<000000-ffffff> : sets color
• a=+ : autocycle = on
• a=- : autocycle = off

TODO :

• edit the 4 lines (50+51, 70+71) with your values :
• #define WIFI_SSID "YOUR SSID" // WiFi network
• #define WIFI_PASSWORD "YOUR WIFI PASSWORD" // WiFi network password


• #define LED_COUNT 60 // number of leds of your strip N°1
• #define LED_COUNT2 80 // number of leds of your strip N°2


• Disable MQTT support if you don't want it (comment line 23) OR Update MQTT Settings (broker, port, topics from line 24 to 27)
• /!\ by default, when your computer is not ON (power led = off), no animation is shown (except some trigger by jack or hdd led if configured so),
So if you don't see any led animation, check that power led pin is connected and on the right way (check polarity).
To disable this behaviour, comment lines from 276 to 294

• print your case (to avoid electrical shorts ^^), 1 available here : https://www.thingiverse.com/thing:4238962
