MEET THE BIT
MINI-CHALLENGE
i5 SLIDE DIMMER
Slide this dimmer back and forth to control your circuit.
As you slide it up, more signal goes to the Bits that follow,
brightening lights, speeding up motors, and raising the
volume on your buzzer.
Can you invent something with the slide dimmer that waves
a flag back and forth? How could you change the speed it
waves?
When the slider is all the
way to the left, it’s sending
an o or 0 volt signal.
When the slider is all the
way to the right, it’s sending
a 5 volt signal. The slider
can be positioned to send
any signal between 0 and
5 volts.
