Web6 mei 2024 · Hi, I want to use a three-legged (voltage divider) rotational potentiometer as an analog input for my Arduino NG rev. C board. Unfortunately, I only have a 470 ohm potentiometer. I'm not sure if I can use this potentiometer with Arduino: it's quite a low resistance (compared to kiloohm potis) - a quick calculation gives 5V/470ohm = ~ 11 mA … Web5 sep. 2024 · Suppose that a pickup produces 100 volts and the potmeter is 100 ohms. When the pot is fully open, the first resistor (R1) is 100 ohms and the second resistor (R2) is 0 ohms. The entire 100 volts goes over the first resistor, because the law of Ohm comes into play. That law gives the relation between voltage, current and resistance: U=IR.
