Hi, I want to do a device that measure the flight time of a vertical jump. I've all the code done. I've used several sensors, , but none of them give me a frequency (at least 250 sample per second).
I'm thinking that a good option is to put an infrared emitter pointed at the tips of the feet, or something like a contact surface, that detect when the feet are supported on the floor or not.
Please, if you have any suggestions, let me know.
I repeat it, I have the code part done, I just need help with the hardware and adapt the code to the new hardware.

HI! If I were you I could use digital short distance proximity sensor with MCU's external interrupt. This will give you nearly real-time measurements in nanoseconds ;) Cheers!
