| Jan 7, 2018 at 19:46 | comment | added | andreas.vitikan | I actually did a measurement just now with a multimeter, and it confirmed what you said. The unregulated voltage from the AA batteries was 6.4 V and the output voltage was 4.8 V from the 7805. Now I don't know what do: if I go over this I can get 5V on the Arduino but I overpower the motors, if I leave it like this the Arduino will be under-voltage. | |

| Jan 7, 2018 at 19:13 | comment | added | andreas.vitikan | Which way should the diode between +5V and Vin go? Also, does this mean that when I connect 6V the output is 4.8V and that is what the Arduino is running from? | |
