IC UM66 PDF

UM66 is CMOS technology melody integrated circuit especially used in to give the output from speaker, when we reset the circuit UM66 will play the melody. The following schematic is for UM66 or BT66 musical IC. You need very few components to make this circuit. Pin configuration for UM66 is. Here is one listing from China for the UM66, and another one from France. Some IC become obsolete and may not be available in market.

Arduino based GPS receiver.

So I’ll suggest changing your schematic to some other doorbell circuit by searching on google: Plz give me the circuit diagram of door bell with BT66t19lresistance ohm, bc Usually this IC is used in greeting cards to make melody sound. I will look for another one. So my question is: You need very few components to make this circuit. Sign up using Facebook. Now connect the battery and hear the melody sound.
