I'm trying to build myself a "MultiWiiCopter" (http://www.rcgroups.com/forums/showthread.php?t=1261382
) with my Arduino Nano 328p, but I've ran into major trouble. The Nano has been working just fine for a while, I've flashed the MultiWii program onto my Nano and I got my Nintendo Wii gyro and accelerometer running like they should on the Windows GUI-configurator. The problem started when I was going to "pack" all of the circuit boards together with some foam material and some rubber bands. All of the boards were working well before I packed them together, but when I was going to try them afterwards, Windows kept giving me an error message in a popup telling me that it can't recognize the device I plugged in. In the device manager, on the unknown device that is the Nano, it says "Windows has stopped this device because it has reported problems. (Code 43)". I think that I may have short circuited the VIN-pin to the GND-pin next to it while external power was connected to it (the BEC from the ESC that was connected to my batteri pack), as I was using open contacts and they may have touched. I'm not that great with electrics, so I want to know if I might have burnt my Nano by doing so, or does it have some built-in feature that prevents this from damaging it?
I actually got the Nano to work again after that happened by uninstalling every USB driver and reinstalling the FTDI driver so that I could use the Arduino software and flash programs to the Nano again. However, when I now, a couple of days after, tried to plug it in again, Windows gives me the same error messages as before. I tried everything I did before, but it won't recognize the Arduino.
When I have the Arduino plugged into my computer via the USB-cable, LED3 keeps going on and off very fast after the boot sequence. It gets power, as the green PWR-led is lit.
Any idea on how I could fix this or will I have to get myself a new Arduino?
Many thanks for taking your time and helping me!
