Arduino use a pot. A potentiometer

Arduino use a pot. A potentiometer

Displays the analogue value of a potentiometer using the serial port

To view serial port press Crtl+Shift+M

There are Linear taper potentiometer and Logarithmic type potentiometer .

For this circuit example a Linear type of is more recommended because this will return a smother Linear value over the turned range

About the Potentiometer on Wikipedia.

Demonstrates analogue input by reading an analogue sensor on analogue pin 0, (A1), and depends on the value obtained by analogRead() displays that analogue value using the serial port.

The range of values returned by the analogRead() is 0 to 1023

A sketch like this may be used to control the angle of something e.g. in a servo

To view serial port press Crtl+Shift+M

The circuit:
* Potentiometer attached to analogue input 0 (Means A0 input)
* center pin of the potentiometer to the analogue pin
* one side pin to ground the other side pin to +5V

No LED's are lit using this sketch but LED TX will flash to show that serial data is being sent when you the view serial port

To view serial port press Crtl+Shift+M
