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_voltageto read the configured setting.
Parameters: pin (Pin) – the pin to read from
Turn off the AnalogIn and release the pin for other use.
No-op used by Context Managers.
Automatically deinitializes the hardware when exiting a context. See Lifetime and ContextManagers for more info.
The value on the analog pin between 0 and 65535 inclusive (16-bit). (read-only)
Even if the underlying analog to digital converter (ADC) is lower resolution, the value is 16-bit.
