This 10K potentiometer module takes a standard rotary potentiometer and mounts it on a small breakout PCB with three berg connector pins, making it straightforward to add an adjustable analog control to a project without any extra wiring beyond the three pins themselves. As the knob turns, its internal resistance changes, and connecting VCC to one outer pin and GND to the other lets the center pin output a voltage anywhere from 0 up to VCC depending on where the knob is positioned.
That analog voltage can be read directly by a microcontroller's ADC pin, giving smooth, continuously variable control over anything from LED brightness to a motor's speed setting or a parameter in a piece of code, rather than the fixed steps a digital input would provide.
Resistance is 10K, a common middle-ground value that works well for most analog voltage-divider applications, and the module runs on a 5VDC operating voltage, matching typical Arduino and similar board logic levels directly. Its board measures 18mm by 23mm by 25mm and weighs about 8g, small enough to tuck into a control panel or a compact enclosure without much trouble.
Because it is already mounted on a PCB with berg pins, it plugs directly into a breadboard for prototyping, or connects via jumper wires to a finished project, without needing to solder the potentiometer itself to anything.
Anyone adding a manual analog control, such as a volume knob, brightness dial or speed adjustment, to an Arduino or similar microcontroller project will find this pre-mounted module a quick, breadboard-ready way to get started.
10K.
5VDC.
VCC to one outer pin, GND to the other, with the center pin giving the analog output.
No, it plugs directly into a breadboard or connects via jumper wires using its three berg pins.
An analog voltage from 0 up to VCC, depending on the knob's position.
