Hi Mokey.
Read the “How to use forum” advices being available, especially #7, how to attach code. Use the tga to the very left, “</>” for code.
People using smarphones can’t download Your code. By some reason not even my Pc can do it. Errors occur. Many members don’t want to create new folders for Your code and later have to erase them.

  if (left == HIGH)

Did you forget to read the state of the pin ?
