Writing code to control the LED in an LED Arcade Button Moderators: adafruit_support_bill, adafruit

I'm pretty new to this, but I'm using CircuitPython and a Metro M0 Express. I am trying to figure out how to turn on/off the Arcade Button w/ LED https://www.adafruit.com/product/3489.

I don't know if there is something special in my code that I need to do, but so far this is the code I have for it.

Code: Select all | TOGGLE FULL SIZE

start_stop_home = DigitalInOut(board.D11)
start_stop_home.direction = Direction.INPUT
start_stop_home.pull = Pull.UP

start_stop_away = DigitalInOut(board.D12)
start_stop_away.direction = Direction.INPUT
start_stop_away.pull = Pull.UP

start_stop_away_state = False
start_stop_home_state = False


But the LED remains on even with the False state.

There is a chance I have it wired incorrectly. I have the buttons hooked up to Digital In 11 & 12. Then I have the LED's hooked up to 5V port. Both running to respected grounds. Tried looking up how some of the projects with these buttons have them set up code wise, but there isn't really much out there on how to get the LED's working responsively.

Thanks in advance

Share your circuit diagram, try using pull up resistor in hardware, I think that will resolve the issue

I got it working. I finally found some code that showed me I needed to connect the led to a digital OUTPUT.

Like so:

Code: Select all | TOGGLE FULL SIZE

button_led = DigitalInOut(board.D4)
button_led.direction = Direction.OUTPUT
button_led.value = False/True

Thank you for following up with your solution. Should be useful to others in the future as well.
