Hello all,
What i'm trying to do, I need one sensor to mount on "the walker" (not on people) so the disability people use it, it will activate the LEDs.I think I will use one IR transmitter and receiver.
The only thing I dont know is that, when the user go (walk), some thing change like displacement, velocity,....which kind of sensor can measure that change, and he stops walking, the sensor stop also.
sensor--------->IR transmitter--------->IR receiver------->LEDs displays
Any links or comments are greatly appreciated.
Thanks
