Hi there folks maybe someone could give me some direction.
I am working on a sound installation and this is my second time using Arduino so please forgive my ignorance. But as many of my maker friends have advised, making the project you want to do is the best way to learn. :D
Project Description: an antenna in the center of a room (possibly mounted on a sculpture, later) that acts as a theremin (without volume control) in the sense that the oscillator gives a frequency input, which can later be turned into a digital output in the form of audio. Here is the base code I used. When a person walks into the room and gets closer to the antenna, depending on the frequency that is received, different audio recordings will play in relation to the body in space. I know this will not be exactly how the antenna works, since other "hot" objects like phones/laptops can also translate into changes in frequency, but I'm ok with that.
I've built the theremin as per the instructions and now I have a few questions of how to proceed. For better audio quality and more processing possibilities I decided to output the serial monitor values received from my Arduino antenna into Raspberry Pi. I imagine that I will have to translate these frequency values into some kind of stepped range, i.e. value range from 60293-63059 will play 1st recording, person moves closer and value range changes, 2nd or 3rd recording will play.
I'm new to coding as well so perhaps someone can give me a hint on how to proceed, and also what other problems I might run into hardware or software-wise.
Also: how can I expand the distance of the range of the antenna? Is it simply a matter of having a larger antenna? :blush: Sorry if these are super newbie questions!
