[Feature] 88005 Light Support

[bricklife]

I tried to use 88005 Light from Pybricks, but it seems that the device is not supported. https://www.lego.com/en-us/product/light-88005

LEGO official applications, e.g. Powered Up app, support it. I think it's almost the same as DCMotor. The IO Type ID is 0x08 as follows: https://lego.github.io/lego-ble-wireless-protocol-docs/index.html#io-typ

Thank you for the request. Yes, we still have to add support for the Light.

Several others have asked the same, so it sounds like we should prioritize this one :smile:

The API will look like this.

[bricklife]

Thank you for your quick response! The API looks good. I'm looking forward to it 🥰

I was creating similar request when I saw this one...Test is on-going now well with 2 motors and light sensor...

[laurensvalk]

Thanks! In the meantime, maybe you'll like to use the builtin light of the ColorDistanceSensor:

my_sensor = ColorDistanceSensor(Port.A)
my_sensor.light.on(Color.BLUE)

[Patlepirate01]

Thanks. Included in my current testing. Will probably do a small video later today

Preliminary API added in https://github.com/pybricks/pybricks-api/commit/80840396aadcfe839946ccf52242fa490b214f81

We'll keep this issue open until it is also implemented & released.

Thanks to @ZPhilo for the LDraw Parts!

Thanks to @ZPhilo for the LDraw Parts!

You're welcome ;) Just made an updated shortcut with realistic cable length (coiled) https://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/22168.dat (don't forget the subpart! https://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/s/22168s01.dat)

Done! :bulb: :rocket: :bulb:

If you refresh Pybricks Code and update the firmware, light support is now included.

Run the example below for some fun tests.

Also please note that from now on you have to include imports explicitly

from pybricks.pupdevices import Light
from pybricks.parameters import Port
from pybricks.tools import wait, StopWatch
from math import cos, pi

# Initialize the light and a StopWatch
light = Light(Port.B)
watch = StopWatch()

# Cosine pattern properties
PERIOD = 2
MAX = 100

# Make the brightness fade in and out
while True:
    # Get the time in seconds
    time = watch.time()/1000

    # Evaluate the cosine
    brightness = (0.5-0.5*cos(time*2*pi/PERIOD))*MAX

    # Turn on the light, wait, then repeat
    light.on(brightness)
    wait(10)

I'll close this issue when some of you have confirmed that it is working. Thanks!

@laurensvalk The example works fine! Thank you very much.

[laurensvalk]

Excellent, thanks for confirming!

I'll close this issue.
