I finally have this module is being used a little differently and not just as a proximity sensor I am interested in it and will get all the 'stuff to make this project. I always had in mind to experiment (always with the HC-SR04 module) and make an ultrasonic microphone and then through conversion to heterodyne, make it audible to the 'human ear. For the time being, thank you.

So many repeats of the same problems, with no reply or update from the OP. As a total newbie to arduino I am feeling that all the money I have spent so far on my arduino and components is a waste of time.

The IC pin 1 is not called out and a different IC part number (cut & pasted from some other unrelated project?) is used. This is exactly why we need a real schematic - not a breadboard drawing. There is no logical flow... Does anyone ever actually read these comments? Why hasn't this project been updated? Shame on the fools who recommend projects without ever actually building them to see if they work!

Hey, many thanks for letting us know about your initiative. Although I'm still relatively new to Arduino, I want to use it to incorporate some hands-free performance components into a multi-sensory experience I'm creating for persons with special needs as part of my MA. Do you believe that this could somehow integrate with Max/MSP so that, rather of utilising a speaker, your output could be a DAW or interface and the theremin would essentially be in control of the programme?

It has so many documentation errors for a project that is intended to represent the "best of" and a "revision of"! First, the wiring is completely incorrect, and then the connection schematic shows the incorrect part number. According to the code wiring notes, the chip's pin 1 should connect to the Uno's pin 9, its pin 2 should connect to the speaker, its pin 3 should be grounded, its pin 5 should connect to the Uno's pin 10, its pin 6 should connect to the Uno's pin 13, and its pin 7 should connect to the Uno's pin 11. Second, the potentiometer chip pinout in the code is incorrect. https://showforapk.com/showbox-for-iphone/

For a project that is supposed to be the "best of" and a "revision of" it has so many documentation mistakes! First - the connection drawing shows the wrong part number, then the wiring is totally wrong. If the code wiring notes are to be believed, pin 1 of the chip should go to pin 9 of the Uno, pin 2 of the chip should go to the speaker, pin 3 of the chip should be grounded, pin 5 of the chip should go to pin 10 of the Uno, pin 6 of the chip should go to pin 13 of the Uno and pin 7 of the chip should go to pin 11 of the Uno. Second - the code has incorrect potentiometer chip pinout for power which will fry the chip: pin 4 should be ground and pin 8 should be 5 volts. I have to ask if the people who love the project just glanced at the idea or actually considered building it...

Hi! Is there anything i can replace the digital potentiometer with?

Please remove this. The code and schematic conflict and do not work. my advice: Don’t go down this rabbit hole.

For a project that is supposed to represent the "best of" and a "revision of," it contains so many documentation mistakes! The connection diagram first displays the wrong part number, followed by the fully improper wiring. The chip's pin 1 should be connected to the Uno's pin 9, its pin 2 to the speaker, its pin 3 to ground, its pin 5 to the Uno's pin 10, its pin 6 to the Uno's pin 13, and its pin 7 to the Uno's pin 11. These connections are specified in the code wiring notes. Second, the code has an erroneous pinout for the potentiometer chip. https://designdeskinteriors.com/

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
