SKU: SF-DEV-15083

The SparkFun Qwiic Twist is a digital RGB rotary encoder breakout with built-in I²C interface. It handles all interrupt management, switch debouncing, and LED PWM internally, presenting encoder position, button state, and RGB colour control over a simple I²C connection via Qwiic connectors. The ...

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-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-COM-27884 · MPN: COM-27884

The CS19D128B is a high-quality magnetic rotary encoder from Cooka, offering smooth, low-friction rotation with 128 pulses per revolution and no detent positions. Pressing the shaft activates a built-in push switch. Unlike mechanical encoders, the magnetic sensing mechanism allows this encoder t...

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: DF-SEN0502

This looks like a potentiometer, but it’s an encoder switch. It is a cascadable 360 ° rotary encoder switch with 20 pulses per revolution, and each pulse corresponds to a detent. There are LED lights set for each detent to allow users visually check the real-time status of the encoder. For ease o...

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...
