Rotary Potentiometer - 4.7k Ohm, Linear
An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user!
This pot has a 1/4" mounting diameter and has a 4.7K linear taper. Check the datasheet for dimensional drawings.

Core Skill: Soldering
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

I am trying to make a variable output. I have connected the negative lead to the negative output and have wired the positive to the potentiometer. My setup is the input on the outer pin and output on the center pin. I have nothing wired to the other outer pin and when i measure the voltage with a multimeter while rotating the pot, it reads as the vcc voltage. What am i doing wrong?
Do I need an IC for this to control voltage? I am a rookie lol... and what is the difference between 10k and 4.7k?
10k -> from 0 to 10,000 ohms 4.7k -> from 0 to 4,700 ohms
a nice panel mount pot at a decent price for a single
How do I know what potentiometer to get? 10k ohm, 4.7k ohm?
quick question, i want to use this as an input to the arduino, just to give me numbers to control the threshold of a sensor, should i use this one or the 10k?
thnx!

Can someone confirm that the Potentiometer Knob (COM-08828) related below does fit these new pots?
In the comments it mentions a cutout for locating and it appears these new pots don't have that.
Cheers,

there are many new knobs available: COM-10001 take a look at the bottom of that product page for more.
I would assume not.
Other commenters have said the friction-fit knob relies on a D-shaped pot shaft. These don't have that.
