I have a techo-event in my high school and I need to trigger a few LEDs and motors after a certain video finishes playing on screen .Any idea on how to go about it?
Can you write a PC program that controls the playing of the video and sends a message to an Arduino when the video is finished.
Alternatively the duration of a video is usually known very precisely so maybe your PC could send a message to the Arduino to do things in XXX miliseconds time?
