SunRobotics 2k ohm Variable Resistor Trimmer Potentiometer(RM065) 10 PCS Variable Resistor  (2000 ohm 30 %)

A general-purpose board mountable preset is also called by other names like potentiometers, trimpots, etc. but is basically just a variable resistor. This potentiometer can also be used as a variable resistor and to generate a variable voltage. To use this potentiometer as a variable resistor, connect the outer two pins to Vcc and 0 V and the center pin outputs a variable voltage between 0 V and Vcc as the potentiometer is rotated. This potentiometers is easy to mount on a PCB and can be adjusted using a screwdriver. Perfect for your next LCD contrast adjuster, opamp setting, or volume level.
