It says that there are errors compiling from my Arduino Uno board. How can I fix this?

    Your code compiles without errors with the "standard" IRremote library. My guess is you did not correctly install the "RobotIRremote" library, or your code is not suited for the RobotIRremote library.

    You really, really, need to include the error messages as part of your question. Without them it is pure guesswork trying to help you.

This can solve your issue:

  • Sketch > Include Library > Manage Libraries
  • In the 'Filter your search' box, type 'irremote'
  • Click on 'IRremote by shirriff'

    library picture


  • Click 'Install'
  • Wait for installation to finish.
  • Click 'Close'.

Then try compiling the sketch again. The error might go.
