BlinkMKnobHue sketch

A regular BlinkM and a BlinkM MaxM doing the tango.

The sketch that controls the BlinkMs is pretty short:

#include "Wire.h"
#include "BlinkM_funcs.h"

const int blinkm_addr = 0;
const int hue_pot_pin = 0;

void setup()
{
BlinkM_beginWithPower();
BlinkM_stopScript(blinkm_addr); // turn off startup script
}

void loop()
{
// read the hue pot, values range from 0-1023, blinkm's 0-255, thus /4
int hue_val = analogRead(hue_pot_pin) / 4;
// set blinkms with hue; brightness & saturation is max
BlinkM_fadeToHSB( blinkm_addr, hue_val, 255, 255 );
delay(50); // wait a bit because we don't need to go fast
}
