Result diagrams of the automatic streetlight control system that switches to DIM at night and HIGH at object detection. (a) In the day-time simulation, the LEDs are not glowing. (b) In the night-time representation, the DIM LEDs are glowing. (c) An object in front of first IR obstacle avoidance sensor; the first set of HIGH LEDs are glowing while the remainder are in DIM mode. (d) Motion in front of the second IR obstacle avoidance sensor; only the second set of LEDs are glowing HIGH, and all the others are in a DIM state.
