Obstacle sense
IR LED and a large-area photodiode to sense a change in incoming light. This actually includes a first for me -- a design using transistors (successfully). The right transistor is a drain to turn the LEDs on when needed. The center transistor is switched by the photodiode to give a meaningful signal out.
