===== Color chooser =====
This example shows how two potentiometers can be used to choose an RGB led.

==== Requirements: ====
  * Uper1 board
  * Two potentiometers
  * Breadboard
  * Connection wires

==== Code: ====
<code python>
from colorsys import hls_to_rgb
from IoTPy.pyuper.uper import UPER1

with UPER1() as board, \
        board.ADC("ADC0") as adcPin1, board.ADC("ADC1") as adcPin2, \
        board.PWM("PWM0_0", polarity=0) as redPin,\
        board.PWM("PWM0_1", polarity=0) as greenPin,\
        board.PWM("PWM0_2", polarity=0) as bluePin:

    while True:
        hue = adcPin1.read()
        lightness = adcPin2.read()

        rgb = hls_to_rgb(hue, lightness, 1)

        redPin.set_duty_cycle(rgb[0]*100)
        greenPin.set_duty_cycle(rgb[1]*100)
        bluePin.set_duty_cycle(rgb[2]*100)
