WebMay 6, 2024 · The Arduino ADC should be stable +/- 1 bit as long as the reference is stable. If you use the default Vcc reference and Vcc as your pot-supply voltage, that should also give you stable readings (+/- 1 bit). Longer wires, unshielded wires, and higher impedance pots will be more prone to noise pickup.
Web2 days ago · Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage (5V or 3.3V) into integer values between 0 and 1023. On an Arduino UNO, for example, this yields a resolution between readings of: 5 volts / 1024 units or, 0.0049 volts (4.9 mV) per unit.
