bonsai - harp behavior board connection

[soyyso]

Hello,

I am trying to turn on an LED on a breadboard using the Harp Behavior Board when a specific key is pressed on my PC.

The workflow logic in Bonsai appears to be correct and properly linked. However, the LED is not turning on. Does the Harp Behavior Board require a 12V power adapter to drive the outputs?

Currently, I only have the board connected to the PC via USB.

Any help would be appreciated. Thank you!

Yes, to drive the outputs you need to connect also the 12V power adapter.

Hi, thank you for your answer.
I connected the power, but it doesn’t work...
Is there anything I should definitely check?

1 - Make sure the electrical connections match this example
2 - Measure the output with a multimeter to check if you have the 5V voltage
3 - Check if the other outputs (D01-3) are working
4 - If you connect the LED directly to LED0/LED1 outputs does it work? Example here
