I am trying to re-create the TTL LC-type Oscillator/Theremin as Capacitative Sensing Device using breadboard and Arduino Uno R3. The code is from:
When I run the code, the Arduino uploads it fine, but I cannot get a signal reading on the Serial Monitor unless I unplug Digital Pin 5. I have attached two pics here showing how I hooked it up. I have tried swapping Arduino boards, but the same happened so I am thinking I messed up somewhere on the breadboard side. I am following the schematic diagram from the website above - I am totally new at this, so any help is greatly appreciated. Thank you!
