Title: infrared detector/emitter
Post by: nckspec on March 30, 2008, 06:49:25 PM

when you are reading the output through your microcontroller for object avoidence would you just use code like : if porta=0 then go straight else reverse). I mean would it matter what it outputs or would you write the code based on if it ouputs anything.

sorry i meant does your controller have to know the exact voltages your detector sends to act upon avoiding an obstacle

analog sensors give a value within a certain range ( you use Analog to Digital conversion)
digital sensors tell you if  a value of 0 or 1

search google for more details, and if any other questions ill answer
