Cool! I'm wondering how this could be used (or interfere) with a Parallax Ultrasonic Ping sensor for Arduino and other microprocessors. Maybe attaching the Ping sensor to a RasPi's GPIO (general purpose in/out) pins will allow for ultrasonic RasBMC remote?
- mbell 13y agoDoubtful, any purpose built ultrasonic sensor will likely be running at much higher frequencies than you can play with via a standard audio chain. The Ping for example runs at 40khz but the most you'll get out of a standard issue audio chain is ~20-24khz, depending on the corner frequency of the analog filters on the input / output and driver / mic response.
