Breadboarding: Adding Two Trimmper Potentiometers to the ADC Channels 1 and 2

Trimmer Potentiometers are small potentiometers intended only to be adjusted on the circuit and these are generally not able to be accessed. For example, a radio has a volume control that my be a standard potentiometer, but if you break open the case and pull out the circuit board, there may be small potentiometers (trimmers) on the board that cam be adjusted with a screwdriver.

The two trimmers are connected to the ADC pins 1 and 2 to adjust a low and high threshold.
