Now i have been looking after some info about when you are making a IR obstracle sensor. Is it realy that important with modulation if it is used indoors? And if it is, how do you get it to work, with modulation?
Most people that have made someting with modulation, dosent describe how you make the reciver modulate, or how you proces the data.
I can easily get the sender to modulate, but my question is, how do i get my reciver to modulate, and how do i proces the data.
