The plain-English version
Hardware that samples an analog signal and represents it as a discrete digital value.
Why it matters
Its range, resolution, reference, and sampling behavior affect the meaning of sensor readings.
Let’s make it click
A program converts a sensor voltage reading into a calibrated measurement.
Vibe Bro’s heads-up
A raw integer is not automatically a physical unit; account for the documented reference and the sensor's calibration relationship.

Supported: ADC sampling/discretization and reference/calibration dependence are correct; raw counts are not automatically physical units.
