Why is my Arduino suddenly not working?!
There are many reasons why the Arduino wont work. Step through some of these suggestions:
- Have you got the needed drivers?
- You can get the software here.
- Did your last sketch use fast serial?
- Lots of serial in a short space of time can flood the host. Try a Cold Boot.
- Are you using Linux?
- Make sure you are taking the right steps for your distro
