Nao Remote IR

The app allow two users with two buttons each to transmit the button state to the Nao Robot.

To transmit IR pulses it need a dedicated electronic board that modulate the pulses from the audio jack and transmit it by Infra Red LED.

It uses 96KHz sample rate that is High Resolution Audio (https://en.wikipedia.org/wiki/High-resolution_audio) so some devices may be not compatible.

User 1 uses button code 1 and 2

User 2 uses button code 3 and 4
