The Arduino Modulino Knob is a practical input module with a rotary knob (potentiometer) that you can use for analog control in your projects. Whether for adjusting brightness, volume, or parameters – the Modulino Knob provides a flexible interface for many applications. The integrated microcontroller digitizes the values of the potentiometer and transmits them via the I²C bus. Thanks to the Qwiic connector, installation is a breeze and requires no soldering at all. Multiple modules can be connected in series, allowing you to easily expand your circuit with additional functions. The Knob is compatible with Arduino IDE, Arduino Cloud, and the Modulino library for Arduino as well as MicroPython. With its robust design and compact form, it is suitable for both educational and maker projects as well as for rapid prototyping.
