I've followed your tuto to build the theremin with the arduino.I've bought all the component today.And it just don't work. I'm using a mac with the last version of arduino (0021) and a Arduino mega 1280.I'm using a breadboard and a steel wire (about 1mm length)I've check the schematic 10 times and everything seem to be alright.It drives me crazy!
Would it be possible to use four hex inverters instead of four NAND gates?
http://interface.khm.de/index.php/lab/experiments/theremin-as-a-capacitive-sensing-device/its a problem with the mega 1280the frequency input is fixed to the t1 timer input on the mega 8/168/328in the code:int pinFreq = 5;the mega 2560 and 1280 has this pin not mapped to the pin headeryou can try to solder a thin cable directly to that pin or just use a arduino uno.martinHOla, como puedo usar el thereming como medidor de distancias?. gracias.
