DIMMER SWITCH
MEET THE BIT
Twist this dimmer back and
forth to control your circuit.
As you twist the knob
clockwise, more signal
goes to the Bits that follow,
brightening lights, speeding
up motors, or raising the
volume on buzzers.
HOW IT WORKS
The dimmer is like the
knob on a water faucet.
The more you turn the
knob, the more the water
flows from the faucet. The
dimmer is similar – the more
you twist it clockwise, the
more electrical signal it
lets through.
