Re: Self Parking Robot Using IR Seeker Sensors.
Your LED identification code is something you should concentrate on now. You will need to do the following:
Create a circuit that will pulse an IR LED at 10Hz and one at 20Hz. I am not sure how easy this will be for you, as I don't know how familiar you are with electronic circuits. There are 1000s of examples on the Intarwebs, Google is your friend
Seeing as you are in Uni, I am sure you'll be able to find someone who can make these for you
As I said before, once you have these two beacons, you will need to write the code to detect them. Setup a loop that will scan the IR Seekers' state at -at least- twice the frequency of your fastest blinker, so that's 40 times per second. You are going to have a tough time distinguishing between the two signals, as you will have to take into account interference and things like that. Another option would be to have both beacons signal intermittently, in other words, have beacon A at 10Hz, blink for 500ms (so 5 blinks), the nothing for 500ms, then have beacon B blink at 20Hz for 500ms (10 blinks), etc. This would make things a lot easier for you
