Topic: RGB led-strip using only 2 digital pins.
Have been playing around with getting some lights to turn different colors depending on whats happening and here is my progress this far:
BOM:
*Adafruit ledstrip: http://adafruit.com/products/306
*Ramps or I guess any board running Marlin with 2 digital and a ground pin free.
*An external power supply for the strip
Instructions:
Straight forward really most of the work is done in the Marlin FW to trigger the event and color changes.
This far I have the following commands working (although my code looks really bad atm):
Power on -White.
Fan on- Green
Fan off- Blue
Homing in progress - Cyan
Homing done - Green.
Not managed to get working:
colorchhange while the bed is heating, I thought this is done by the m190 command, but cant seem to fork to it in a working matter.
Will get back with a better write-up soon.
Ideas for colorchnage on the bed heating would be nice.
