Students use Arduino microcontrollers and light-sensitive resistors (photocells) to sense the ambient light levels in a room and turn LEDs on and off based on those readings. They are challenged to personalize their basic night-lights with the use of more LEDs, if/else statements and voltage dividers—an open-ended project with endless possibilities.
