Hello,
I want to design a keypad that is based on ir. The idea is there will be a grid of ir emitters and receivers in both x and y direction. The intersection of ir beams would determine the button.
is this project doable?
what kind of ir should i use? do i need to consider the beam angle of the emitter?
thank you.
