How to make the UM66T melody generator circuit
HOW TO MAKE THE UM66T MELODY GENERATOR CIRCUIT The electronic circuits are used to get alarm sounds to attract human attention. From a long-time ago electric bell, alarm circuits, and buzzers were used to draw human attention and those devices are limited to one type of tone. Sometimes alarms are not appropriate to the installed location and the purpose in which it has been used. Presently circuits are used melody generators to make a suitable sound. The UM66T Integrated Circuit is a common melody generator. This Integrated Circuit is based on CMOS LSI design and its melody is stored in 62-note ROM (1) memory. (note: The IC ROM size is changed according to its manufacturer.) UM66T Integrated Circuit has a series of packages. According to your project, you can select a suitable IC Package for your circuit. The packages available song series are listed in the following table. According to manufacture, it has code variations such as UM66, FT66, and BT66. I am
