WebSo if you adjust the wiper such that the value is half the total value, then at the wiper you'd get half the amplitude of the signal, whether the overall value of the potentiometer was 89K or 120K. Janelis • 3 yr. ago Cool! Just got myself like 40/50 of those then :) thanks for the reply! InductorMan • 3 yr. ago WebUse the AnalogIn API to read an external voltage applied to an analog input pin. AnalogIn () reads the voltage as a fraction of the system voltage. The value is a floating point from 0.0 (VSS) to 1.0 (VCC). For example, if you have a 3.3V system and the applied voltage is 1.65V, then AnalogIn () reads 0.5 as the value.
