The microcontroller of the board has a circuit inside called ananalog-to-digital converterorADCthat reads this changing voltage and converts it to a number between 0 and 1023. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value ...
Arduino Due does not have an analog output voltage from 0 V to Vref, but from 1/6 to 5/6 of the reference voltage, that is, 0.55 V and 2.75V with Vref = 3.3 V. This is also confirmed by the Atmel (see bibliography). The output voltage range of the DAC is only 2.75-0.55 = 2...
In normal analogRead use, the reference voltage is the operating voltage of the board. For the more popular Arduino boards such as the Uno, Mega boards, the operating voltage of 5V. So if you have a reference voltage of 5V, each unit returned byanalogRead()is valued at 0.00488 V. (This...

By default, ymax is the operating voltage Vcc. The analog pins can only be output positive values. If the output is negative, the absolute value is output. A second digital pin can be used to indicate when a negative value is output on the analog pin. The absolute value is output on...
