@kaimo Hello, I'm very basic in Pure Data and Raspberry Pi and I also wanted to create a sound box that reacts to the approach of objects to generate sounds. After a few hours of research and chatting with ChatGpt I managed to create a simple prototype. To write the Python code I used PyCharm on the Raspberry Pi, bearing in mind that it is necessary to install libraries related to GPIO and OSC (since to communicate with Pure Data it is necessary to use netreceive). If I can help you, I'd be happy to share my experience with you. Here you go. Cheers and good work
