Part 3 of this tutorial is so big we have spread it over 4 installments. This blog post is just to pull all of those post together in a single location.

Part 3a: Sending IR Codes
In this segment we create a small Arduino sketch that allows you to type IR codes into the serial monitor and have them transmitted by your IR LED.

Part 3b: Creating a Virtual Remote Using Python
In the segment we use a Python script on a PC or Raspberry Pi to communicate over the serial port with the Arduino. By clicking on the virtual buttons on the PC, the Python script transmits the codes to the Arduino which in turn translates into your device by your IR LED.

Part 3c: Python, PySerial and PyGame Installation on Windows
Because Python and the other tools for creating the Virtual Remote may not be on your system, we have included this extra tutorial on how to install the necessary software on a Windows PC. While it isn’t technically connected to IRLib, we thought it would be useful to a variety of people not just users of our library.

Part 3d: Installing the Arduino IDE on a Raspberry Pi
Again this is not strictly related to IRLib but if you want to run the Part 3b example on a Raspberry Pi you will need to install the Arduino IDE. General users of Arduino and Raspberry Pi might be interested in this even if they do not use our libraries. If you do not use a Raspberry Pi then you do not need this part of the tutorial.
