Is there any similarity between UM66 ic and BT66T 19L?
no there is no similarity. they both use for same purpose to produce melody tone in alarm
What is the working of HLS5T03 IC in musical burglar alarm?
This circuit generates a sweet melody for two minutes when it detects the shadow of a moving person. It uses the ROM IC UM66 to produce the melody. The music stops automatically. LDR is used as the light sensor. In day light, its resistance is low and conducts. This keeps the base of T1 high and it remains off. When the shadow of the moving person falls on the LDR, its resistance increases and the current flowing through it decrease. T1 then conducts and C1 charges. This provides power to IC UM66. Zener diode ZD is used to regulate the supply voltage to UM66 to 3 volts. When UM 66 gets 3 volts supply, it oscillates and the music tone from it will be amplified by T2 which can be heard through the speaker
