Web6 mei 2024 · Connect one end of the potentiometer to 5V, the other end to ground, and the wiper to your analog input. Assuming you have a linear potentiometer, the voltage read by the ADC will gradually go from 0 to 1023 as you rotate the potentiometer from one end to the other. If you want to know why, google resistor dividers. Web29 jan. 2016 · There are different ways, but always it is introducing some current (I) to the "unknown" resistance and measures the voltage drop (U) across the resistor. Then it shows the value with using the formula R = U / I. Now in a powered circuit in almost any case there is current and voltage across the resistor (else it us not working).

Web6 mei 2024 · Vout = 5V * 5000/ (5000+5000) = 2.5V. So the overall value of the pot doesn't really matter. Where the value does come into play is how power it dissipates. Power = Current x Voltage, or P=IV. Current = Voltage/Resistance, so a 5K pot with 5V will have 5V/5000ohm = .001A, 1mA going thru it. Power = .001A * 5V = 5mW, which is not much, … WebThe TPL0102 has two linear-taper digital potentiometers with 256 wiper positions and an end-to-end resistance of 100 kΩ.
