Hi,
I'm building a door chime based on the PIR sensors,but I can't find a suitable "ding dong" tone generator circuit .
I bought a motion sensor kit from Elenco Kits which uses one microprocessor for generating the tone I don´t know where to find a dealer for that chip .
Any help with this project will be much appreciated .
Thank you .
