.:Potentiometers:.
Along with the digital pins, the Arduino also has 6
pins which can be used for analog input. These
inputs take a voltage (from 0 to 5 volts) and convert
it to a digital number between 0 (0 volts) and 1023 (5 volts) (10 bits of
resolution). A very useful device that exploits these inputs is a potentiometer
(also called a variable resistor). When it is connected with 5 volts across its
outer pins the middle pin will read some value between 0 and 5 volts
dependent on the angle to which it is turned (ie. 2.5 volts in the middle). We
can then use the returned values as a variable in our program.
