Trigger psychopy stimulus with Arduino

I am using PsychoPy to trigger a visual stimulus for an experiment with mice. I will have a screen with the stimulus and I want to trigger it using an Arduino. Any hint on how that can be done?
Thank you very much :slight_smile:

This paper may help you although they connect to eprime instead of psychopy

A simple hardware solution is to use a U-HID ( to mimic keystrokes. The U-HID will read a 5V from the Arduino and output any keystroke that can be read by PsychoPy.

I will look it up, thank you very much!
