but when it is in the circuit and connected to the USB or the actual 9Volt battery in the circuit i get nothing at all not even the power switch on the Arduino.
i had breadboarded it and everything worked accordingly beforehand... should the voltage at pin a0 and the 5v be checked when the circuit is in full swing and connected to the amplifier? when i connect the usb to power the circuit the arduino heats up very quickly so i havnt tried to do that again. the battery isnt flat either i checked it
