Tracking

IR light reflection switch, useful for obstacle avoidance or line following on models that move around the floor. An obstacle in front of the sender/receiver diodes will cause the ‘out’ pin to be pulled low (active low). A pot allows adjustment of the circuit’s sensitivity. The detection distance can be up to approximately 1 cm.
