There is a mistake on the schematic - pin 7 of the digital pot is shown as going to the 5 volt bus even though the wire is black - so it should go to ground.

Hello! I am vey new to coding. I was wondering is there were any libraries that I needed to download? I keep getting an error in the code that says, "fatal error: NewTone.h: No such file or directory. Same thing with the "NewPing.h" too.

I have the same question as someone before me, what is the IC used, is it a LM358 or a MCP4161?

Hi there, I would like to build this Theremin, but I need n explanation: on the component and supply list there is a potentiometer MCP4161, but on the schematics there is a LM358 that is an amplifier. Could you clarify? Thanks. Sam

HEY, thanks so much for sharing your project. I am very new to Arduino but am looking to use it to integrate some hands-free performance elements into a multi-sensory experience for people with additional needs, that I am developing as part of my MA. Do you think that this could link up with Max/MSP in some way so that instead of using a speaker you could use a DAW/interface as your output and essentially have the theremin controlling the software? Many thanks Benny
