An analogue trimpot (trimmer potentiometer) sensor module from the ELECFREAKS PlanetX series, designed for use with micro:bit via RJ11 connection. The potentiometer provides stepless rotation over a 0°–300° range, outputting a variable analogue voltage that can be used to control sound levels, LED brightness, motor speed, and other parameters.
Key Features
- 300° Rotation Range – Stepless analogue adjustment from 0° to 300°
- Analogue Output – Variable voltage output proportional to dial position
- PlanetX Compatible – RJ11 connector for easy plug-and-play with PlanetX expansion boards
- micro:bit Ready – Designed for use with micro:bit and PlanetX shield
Ideal For
- Adjusting sound volume, LED brightness, or motor speed
- Learning about analogue inputs with micro:bit
- Interactive control interfaces in student projects
Package Contents
- 1× PlanetX Trimpot Sensor Module
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
