Hi, Could I have help (circuit diagrams etc.) for an Infra-Red (IR) transmitter/receiver with a low tolerance to ambient light. What I have in mind is the design of an obstacle avoidance circuit. Sort of similar to the IR system used in autofocusing cameras without the circuitry for computing the distance. David email address: nyarko@bode.ee.ualberta.ca
