I have been working on a NERF gun mod with my arduino, and all of a sudden it stopped working! The board powers on, and the power light (green), and an orange light indicated as “L” on the board stays on. I had been using a 12volt battery to power the board very successfully for the last week.
The board in question is an Arduino UNO SMD Edition R2. Im using windows 7 64 bit.
I have read on the website that I need to jump pin 5 and 6 on the 8u2 connector to put the board into DFU mode so I can use FLIP to reprogram it. I am having no luck with this, Windows doesn’t recognize the device at all.
Have I toasted my board? Any suggestions?
