Hi everyone. I am bulding a theremin device which can work with camera. Camera will dedect hands position and will produce amplitude and frequency signal. I have a code and I plan run it in computer. It produce sound in computer but I need to generate this signals on phisical circuits. I wonder how will I seperate this signal send to my amplifier and oscilator circuit?
The first advice is reading and using this link: How to get the best out of this forum - Using Arduino / IDE 1.x - Arduino Forum
With the lack of detail in your post you have no hope that anybody will be able to help.
If there is an Arduino involved
- How does the Arduino communicate with your physical circuits? Analogue signals? Ethernet? Serial? Other?
- How does the Arduino communicate with the PC? Analogue signals? Ethernet? Serial? Other?
- What are the protocols involved?
If there is no Arduino involved, how is the communication between the PC and the devices. Analogue signals? Ethernet? Serial? Other?
And possibly so much more that we need to know.
Why not just build a theramin ?
Have you tested your camera system - quite a task in itself ?
If your camera system and code produces Xand Y co ordinates then send them to the PC over a serial ( RS 232 or USB) signal .
As said your description is pretty vague
