You can connect the positive DC output to Vin, and the negative output to any GND. Set the adapter to 9V. The only thing the PWR jack has that the Vin does not, is a power diode that protects against incorrect polarity (the + and - reversed). The Vin does not have that protection, so just don't hook it up backwards. | |

However it outputs via a negative and positive wire. So inputting directly to the vin pin is the same as inputting DC through the power jack? I would just need to connect positive DC output to vin and negative to any ground on the arduino, and that would give me a regulated 5V output on the 5V pin? | |
