Potentiometer diagram

Sensing Position or Distance
This is lab 6 of 10 in the course
Discover the difference between potentiometers and encoders then use them to find position. Students set up a potentiometer circuit and measure how voltage changes with rotation of the knob, converting voltage to position in degrees. Students then set up an encoder circuit and investigate how the counter input can be used to measure encoder rotation. Finally, students use this knowledge to create a light dimmer and a volume controller.
