RemoteTone : a Raspberry Pi, an Asus AI Remote, and some noise
This is a try to work with an Asus AI Remote from a (dead) Asus motherboard package and a Raspberry Pi, using Python programming language.
The buzzer used seems to be a 5V one because of the low sound output on a 3.3V GPIO pin.
The sound wave is a square one as I can't control level outputs (0V or 3.3V only), and the frequency is not very regular (you can hear scratches) due to the buzzer quality and the non real-time quality of the platform : you have to deal with OS interrupts and Python garbage collecting.
