In this tutorial you will learn how to change the analog-to-digital converter (ADC) on an **Arduino UNO R4 Minima** board. By default, the resolution is set to 10-bit, which can be updated to both 12-bit (0-4096) and 14-bit (0-65355) resolutions for improved accuracy on analog readings.

To use it, simply include it in your `setup()`, and use `analogRead()` to retrieve a value from an analog pin.


```arduino
void setup(){
analogReadResolution(14); //change to 14-bit resolution
}

void loop(){
int reading = analogRead(A3); // returns a value between 0-65355
int reading = analogRead(A3); // returns a value between 0-16383
}
