hi guys, this is Rahul
very interesting comments from all of you.
I have been working on a similar type of project
and I have stuck at one point.
actually my project is, whenever a car comes between the IR sensor and photo transistor, a message should be sent from the transmitter (which is interfaced with the controller 8051) to the receiver inside the car which has intersected the IR beam,
so to do this ,firstly I need to interface ir sensor with the ADC and then to 8051
so can any one please help me in the circuitry of this interfacing part please??
thank you,
A.Rahul
