Arduino has shared the ML Magic Wand project as a demonstration of its Nano Matter board, showcasing how machine learning can turn a simple wand-like device into a gesture-controlled smart home interface. This project enables users to execute specific gestures to control smart home applications, removing the need for traditional input methods.
At its core, the project utilizes the Arduino Nano Matter board, powered by the Silicon Labs MGM240S microcontroller. This board supports the Matter over Thread protocol for reliable smart home connectivity and includes a Matrix Vector Processor (MVP) for efficient on-device machine learning inferencing, enabling rapid gesture recognition.
The project also incorporates the Modulino Movement Node, a carrier board equipped with a 6-axis accelerometer and gyroscope. This sensor module captures precise motion data from the wand, providing raw input for the machine learning model to analyze and interpret specific gestures.
On the software side, TensorFlow Lite is used to develop and deploy the gesture recognition model. The model is trained to recognize patterns linked to specific gestures—such as tracing a “W” to activate a device or an “O” to turn it off. The Arduino Nano Matter board processes sensor data locally, running the ML model in real time to interpret user gestures and send commands via the Matter protocol.
By integrating edge AI with IoT, the ML Magic Wand project highlights how Arduino’s Nano Matter platform enables intuitive, gesture-based smart home control.
