Hi All,
I have constructed an LED button switch reaction time measurement game from the project hub Measure your reaction time © GPL3+ instruction, link below. I have it working and I want to replace the button switch with the shock sensor module.
From looking at the oscilloscope, I believe the problem is that the shock module produces a spike signal. Whereas, the button produces a square-like signal. To test my hypothesis I used a tilt module sensor which produces a signal more like the push button and it works.
If this is the issue it may be due to the trigger setting in the code? I have attached it please have a look or if anything else comes to mind please let me know.
This is my first Arduino project so thank you for your time! 
Many thanks,
Rob
