LIGHT SENSOR
Use this Bit to control your circuits with light! The amount
of light shining on the sensor will change how your circuit
behaves. It's a great way to activate your circuit without
hands and is perfect for alarms!
Can you invent something that moves when the lights go out?
The light sensor measures
how much light is shining
on it. It has two modes.
In
LIGHT
mode, as the
light shining on the sensor
gets brighter, more signal
passes through it (making
lights brighter or motors
turn faster). In
DARK
mode,
the signal increases as it
gets darker.
Use the purple screwdriver to
turn the dial and adjust how
much light it takes to change
the signal. Clockwise
increases sensitivity, counter-
clockwise decreases it.
