FAQs
Can I connect multiple Modulino® Knob nodes to a single Qwiic connector?
Absolutely! You can connect several Modulino® Knob nodes to the same Qwiic bus. To do this, you'll need to assign a unique I²C address to each Modulino® node. The Modulino® library includes an example sketch called AddressChanger that simplifies this process.
What kind of data can I expect to read from a Modulino® Knob?
The primary data you'll read from a Modulino® Knob is the rotary value of its encoder. This provides a continuous numerical representation of the knob's rotational position, allowing you to track its turning and use it for analog-like control or menu navigation. If the Modulino® Knob also features a push button, you can additionally read its digital state (pressed or released).
Is a Qwiic cable included with the Modulino® node?
Yes, each Modulino® node is packaged with a 5 cm Qwiic cable, so you can get started right away.
Are the Modulino® nodes compatible with other Qwiic devices?
Yes, the Modulino® nodes are designed to be compatible with other devices that adhere to the Qwiic standard and operate at 3.3V. Always double-check the voltage compatibility of any Qwiic devices you intend to use together.
What voltage do the Modulino® nodes operate at?
The Modulino® nodes are designed to operate at 3.3V. Ensure that your microcontroller or other Qwiic devices provide this voltage level to avoid damage.
Do I need any special libraries to use the Modulino® nodes with Arduino?
Yes, you'll need to install the Modulino® library either for Arduino language or Micropython, which provides functions and examples to easily interact with the nodes.
Are there any example sketches available to help me get started?
Yes, the Modulino® library, for both Arduino code and micropython, includes several example sketches that demonstrate basic functionality. You can also use the Arduino Cloud templates to discover quick projects using the Modulino nodes.
