Lab 4 - Potentiometer Challenges


Mandatory Challenges:

Challenge #1 - LED indicators

Make a circuit with LEDs in a row.  The LEDs will light up one at a time in proportion with how far the potentiometer is twisted.

When the potentiometer is turned all the way left, all LEDs are off.

When the potentiometer is turned 25% of the way right, the first LED goes on.

At 50%, the 1st and 2nd LEDs should be on

At 75%, the 1st 3 LEDs should be on.

At 100%, all the LEDs should be on.
