Analyzing TTL-Signals
Hello everyone,
I'm using a the TSL 230 it has an TTL-Signal as Output. I read this TTL-Signal about the Line I Port of my Computer. I have to recognize the human pulse with it. So i build an Ultra-Bright LED over the TSL. But i don't know how to recognize this small Differnces in the Signal. Also the Room light doesn't seems to be very regluar, so i don't now wether the room light is it or my pulse.
MFG
