    Hi guyz,

    I would like you guyz to provide me with some very informative ressources (links, pdf files, whatever,...) about 'Ultrasonic Distance Measure' and ' making diferent tones by playing with frequencies...in order to for instance make alarms...'

    Kindly Regards, Eric

    Thanks MrChips! I'll have to do some readings to understand how those things work then implement my own with of course a pic uc!

    I always had a liking for the Ping)))

    I have a dim memory of this product being a clone of someone else's work, and a full schematic of the device was online, but I cannot find a link to that.

    Here is a cheap and dirty clone.

    Typically you will need an amp for the receive transducer. These things work at 40KHz so that is pretty simple. The one I made was for a 3MHz system and making a 60dB amp at that frequency took me a while to work out.
