  • I was able to get auto reset to work by adding a header to the hole marked ‘4’, connecting that header to a 100nF capacitor and connecting the other side of the capacitor to the reset pin on the ATmega328.

                                 Vcc o     o  
                                 Gnd o     o D0
             10kOhm    100nF         o     o D1

    It would be nice if these came with 5 pin headers, or at least on the side where pin 4 is to make this easier.
