Microcontroller Based Pest Repeller Project

This was a project i've realised for my girlfriend for some uninvited guests at her home. :) And the circuit worked great on them. I've worked out the techniques of repelling different kinds of uninvited guests on the net. I've found that high frequency sound signals (namely ultrasonics) repel quite a big number of animals including mice, dogs, cats, hamsters, guineapig, lots of insects, bats etc. etc. But the frequency levels for different animals also differ a bit. So i've designed a small circuit which will apply an amplified signal to a piezo transducer with a continuously & randomly changing frequency within the limits which REALLY REPELS our NICE friends.
