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.
