Programming: ADC (Analog to Digital Converter) Establishing Multiple ADC Channels for Two Trimmers
Share
Two trimmers are connected to the ADC one on channel 1 and the other on channel 2. The pressure sensor is connected to channel 0. The two trimmers will be adjusting a low threshold and a high threshold for the pressure sensor and pin output function.
