in the video below i think the guy is using the arduino infrared module kit (link to ebay item below too)
i wanted to see if anyone here know if we can use this kit as edge detection. so my wall-e doesn't fall of the table.
in the video it shows that if even one sensor (either the transmitter or receiver ) go off the table the bot stops and reverses....
Can i assume the 2 sensors are always communicating the same voltage/value?
and once that value changes (table is no longer there) the scrip command is to back up?
thanks in advance
