This device is a simple & economic way of generating electronic tones. This kit is primarily intended for use as a replacement for the traditional mechanical doorbell. Of course, it can also be used for many other types of applications. The number of tones may be selected up to a maximum of three, each of which is output one after the other. This can be used to help locate the place being called. Volume & tone can also be set. The existing bell transformer can be used as a power supply. ...
