My LG smart TV every few days makes a painful logout of my Netflix account. Enter email and password with the remote controller's arrows is something that turns me really mad. So I decided to find a way to automate this process. First I tried with some HID emulator devices, but the TV does not recognises them. Then I move to capture de IR codes and put them into a simple program on an Arduino PRO mini which solve all the hard work.https://youtu.be/5NW-sDfQXHE
Once you decode the necessary buttons, arrows and OK button in my case, you can program how to "navigate" the keyboard. The keyboard starts at "g", it is as simple as 3 times right button and OK for pressing a "k". With this logic you can enter your complete email address and then the password.
The code is really simple, there are several ways to improve it, but I wanted this quick solution for a daily problem and can't wait a long to have it working. To minimise external components I use the reset button to initialize the sequence.
