analogReadResolution()
Set resolution of ADC used in analogRead(). This means that it will map input voltages between 0 and Vcc (about 3 V) into integer values between 0 and 2resolution-1. analogReadResolution(resolution) resolution the number bits to use: 1–16 None Most popular resolutions are:| resolution in bits | Description | range of values returned by analogRead() |
|---|---|---|
| 10 (default) | Arduino Uno compatibility mode | 0–1023 |
| 12 | maximum possible in Z-Uno | 0–4095 |
| 8 | can save energy in battery devices (uses special mode of Z-Wave MCU to make ADC faster) | 0–255 |
