      I think what I need is an FTDI adapter to do this. Is this correct?

      If so, would it need to be 3.3v or 5v?

        You will need the UsbAsp programmer to program atmega. The maximum supply voltage can be found in the atmega datasheet because it depends on these few letters or numbers after the inscription 328
