How can i tell the value of a potentiometer

Web16 de jun. de 2015 · If you take one physical sample of a potentiometer and test it, you may get a very favorable result. This might lead you to believe that this pot (or that pot) works really well and is stable in end-to-end resistance, ratiometrically pretty good and generally it makes you happy and confident. Web6 de mai. de 2024 · Vout = Vin * R2/ (R1+R2) where R1 is the resistance between Vin and Vout, and R2 is the resistance between Vout and Ground. If the knob is halfway, then R1 = R2, so the equation simplifies: Vout = Vin * R1/ (R1+R1) so with 5K: Vout = 5V * 2500/ (2500+2500) = 2.5V. and with10K Vout = 5V * 5000/ (5000+5000) = 2.5V.

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. 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.
