Question: Why is my Arduino suddenly not working?!

Answer: 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
