Color

class devices.Color(ev3handle, layer=1, portnum=1, inputmode='ambient')

The class to represent the EV3 color sensor.

Set up a color sensor on port number 2

>>> from pyev3.brick import LegoEV3
>>> from pyev3.devices import Color
>>> myev3 = LegoEV3(commtype='usb')
>>> mysensor = Color(myev3, portnum=2, inputmode='rgb')

Parameters

• ev3handle (object) – LegoEV3 instance representing the EV3 brick.

• layer (int) – The layer of the brick 1 or 2 in a daisy-chain configuration.

• portnum (int) – The brick input port connected to the sensor. Possible values are 1, 2, 3, or 4.

• inputmode (str) –

  • 'ambient' ambient light intensity

  • 'reflected' reflected light intensity

  • 'color' surface color

  • 'rgb' surface color RGB components
