Recently we have been helping several members on the Arduino forum to record and playback their remote control signals from their Air Conditioners. These signals are typically much longer than those of TVs or common media devices. The 2 most popular libraries for Arduino, IRremote & IRlib are excellent, but have some limitations which we have covered in a previous post. In this post we address one particular issue that is proving challenging to users.
Over the last few months we have been regular contributors to the Arduino and other forums, answering questions about Infrared remote control projects. It became apparent that beginners typically trip up on many common ‘pitfalls’. So we decided to list off our ‘Top 10’.
