SKU: SF-COM-13253

This is a single pole, 10 position rotary switch able to select up to 10 different states in a durable package. Unlike our other rotary switch, this model is much more robust and capable of handling larger currents and voltages. You may find this rotary switch familiar, it’s the same one we tr...

SKU: SF-BOB-13099

The SparkFun Rotary Switch Potentiometer Breakout is a small board the allows you to add resistors to a 10-position rotary switch, turning it into a potentiometer with 10 discrete steps. Multiple applications require potentiometers that are hard to find due to specific resistance values or cus...

SKU: SF-COM-29199 · MPN: COM-29199

This adjustable dual-gang potentiometer gives you two linked variable resistors on a single shaft, making it handy for interfaces where two channels need to move together. Turn the shaft and the resistance changes, so it can be used to create a variable voltage for an analogue input.Connect VCC t...

SKU: AF-2925

When you need a lot of options, you need a Mini 8-Way Rotary Selector Switch. This is basically a single-pole to 8-throw switch. As you rotate the knob around, the middle pin will make contact with each of the outer pins. Rotary switches are very simple to use and are also nice and compact. Th...

SKU: SF-ROB-30118 · MPN: ROB-30118

Stepper motor builds often need a microcontroller, a separate driver, a 12V or 24V supply and plenty of wiring. This compact controller from Things by Josh brings that stack together in one unit designed to mount directly to the back of a standard NEMA 17 stepper motor.Power comes in via USB-C Po...

SKU: DF-SEN0156

A rotary switch is a switch operated by rotation. It is often used when more than 2 positions are needed, such as multi-speed control. The Rotary Switch uses an analog input to read the 12 state which saves IO resource for the Arduino. This Rotary Switch Module has 12 positions. Each p...

SKU: AF-377

This high-quality 24-pulse rotary encoder features detented rotation with a satisfying click at each step, a built-in push-button switch, and a panel-mount design. It comes with a soft-touch knob with an arrow indicator, making it a complete input solution for projects requiring rotational select...

SKU: SF-COM-14624

A panel-mount rotary potentiometer with a 100 kΩ logarithmic taper. Turn the knob and the resistance changes smoothly — ideal for volume controls and other audio applications where a logarithmic response matches human perception. Connect VCC to one outer pin, GND to the other, and the centre pin...

SKU: AF-5531

This Anodised Aluminium Machined Knob in gold is a premium upgrade for any rotary encoder or potentiometer. Solid machined aluminium with knurled sides for a secure grip and a shiny anodised finish that looks right at home in a recording studio. A white triangle indicator on the top lets you see...

SKU: DF-SEN0686 · MPN: SEN0686

This circular flexible potentiometer is a membrane-based position sensor for adding low-profile rotary or angular input to space-constrained electronics. Instead of using a bulky mechanical rotary switch, it detects pressure along its sensing ring and provides a linear analogue voltage signal fro...

SKU: DF-SEN0448

A 4-wire slot-type photoelectric switch with integrated optical transmitter and receiver. The 5mm detection slot can detect objects passing through, including transparent materials, making it ideal for counting, position sensing, and high-speed object detection in industrial and hobby application...

SKU: PI-COM1005

You'll find these rotary potentiometers in our Maker Essentials kit, but they're so useful we decided to offer them on their own! Pair them with something like our Explorer HAT Pro or Explorer pHAT to read precise values from them. Total resistance: 1kΩ, 10kΩ or 100kΩ Total resistan...

SKU: SF-COM-10613

A digital potentiometer that lets you control a voltage divider with serial signals from your microcontroller. Wire it up like a standard potentiometer, then use digital commands to adjust the wiper position — no mechanical knob required. Because the wiper is software-controlled, you're not lock...

SKU: SF-BOB-11040

The SparkFun LED RingCoder Breakout provides a visual position indicator for rotary encoders. Two 8-bit shift registers drive a circular LED bargraph that displays the virtual position of the encoder as it turns, giving clear feedback on where you are within a range of values. This RGB revision ...
