What did i do to my IR breakout board

My IR breakout board was working, I made a car out of it, but now the red light doesn't turn off. I think this happened by putting 18v into it. Is it able to be fixed?

Posting tips.

  • Always list the version of the IDE you are using and the board version if applicable.
  • How to insert an image into your post. ( Thanks Robin2 )
  • Add your sketch where applicable but please use CODE TAGS ( </> )
  • Add a SCHEMATIC were needed even if it is hand drawn
  • Add working links to any specific hardware as needed (NOT links to similar items)
  • Remember that the people trying to help cannot see your problem so give as much information as you can

Putting 18V on something that probably was designed for 5V (you did not give details of the breakout board) will result in sudden death.

Throw it away and buy another one.
