Hi
I have a Sparkfun mp3 trigger v.2 working with a SHARP
GP2Y0D340K distance sensor.
At the moment the mp3 file is triggered when someone gets close to the sensor.
My problem is that I would like to invert this: A sensor is at all times blocked by a window. When someone opens the window the mp3 files starts playing.
I only have the sensor and the mp3 trigger. I don't have time to build anything new or use a different sensor whereas I'm stuck at a museum with a deadline tomorrow.
If you can help me I hope for a quick reply!
Thanks!
