AnalogIn – read analog voltage¶
Usage:
import analogio
from board import *
adc = analogio.AnalogIn(A1)
val = adc.value
-
class
analogio.AnalogIn(pin)¶ 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 -
deinit()¶ Turn off the AnalogIn and release the pin for other use.
-
__enter__()¶ No-op used by Context Managers.
-
__exit__()¶ Automatically deinitializes the hardware when exiting a context. See Lifetime and ContextManagers for more info.
-
value¶ 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.
