Hi. How do I wire a 3 pin 10k wheel potentiometer? Also, a schematic for one would be appreciated :slight_smile:

There are over 400,000 hits with the search for "arduino potentiometer tutorial". It is one of the most common sensors to connect to an Arduino. How is your potentiometer different from the ones in the tutorials?

In any case, we can't really help without knowing exactly what pot you have and what Arduino board to which you wish to connect the pot. Post a photo and/or a data sheet of the wheel potentiometer.

Give us a link to your part.

Generaly, 1 or 3 goes to +5V, 2 goes to the Arduino analog input pin, and the other goes to Ground.

But be careful of the 0.05 watt rating in what ever circuit you use.

what do u mean?

Your part says 10K Ohm 0.05W (50mW).

That wattage is 50mW (1/20th of a watt).

If you were to connect the potentiometer between 0 and 5v, your 10k potentiometer would consume:
E 2 ÷ R = Watts
25 ÷ 10k = 2.5mW which is < the 50mW rating so all is fine :slight_smile: .

Ohhh i understand 0.05=50m :slight_smile:

0.05W is the maximum power rating of the potentiometer.

You can power with less than 0.05W with no problems.

If you tried to connect it to a much higher voltage than 5v and exceeded the .05W, you could burn out the component, however, at 5v you are safe.
