I hooked it up today and tried it. LED 13 flickered and then it powerd up. The only thing to display on the screen are several pixels in the bottom right of the 16x2 LCD. The differenced between my obdguino and the schematic are that I used a 511 ohm resistor (only thing I could find) instead of a 510 and a 2n3904 (had one handy) instead of a 2n3906. If any of this would make the difference let me know and I will go to radio shack.
