WebDec 1, 2024 · ADC controls how accurately it can read a voltage. For example a 12-bit ADC can represent analog voltages with 12-bit values, i.e. 0 to 4095 (use the equation 2^12 - 1 to understand how the number of bits relates to the possible values). This means the 12-bit ADC can see 4096 different voltages (remember 0 is a unique value too). That’s WebRead analog voltage levels Usage: import analogio from board import * adc = analogio.AnalogIn(A1) val = adc.value Use the AnalogIn on the given pin. The reference voltage varies by platform so use reference_voltage to read the configured setting. Parameters pin ( Pin) – the pin to read from value :int ¶
