Melody Generator using IC UM66

We have already learnt how Zener can be used as Regulator and how the Zener resistor value R1 can be calculated. You need a voice recorder circuit interfaced with a amplifier circuit. Arduino based GPS receiver. In this circuit please don’t give the supply beyond 3 volt without.

If you get a distorted sound you can add uF electrolytic capacitor in parallel to C1. Whistle to Beep Circuit. The volume of the sound of this circuit is so much that it can be used as a calling bell. Resistor R1 limits the base current of Q1 within the safe values. C1 is used to decouple power supply to avoid inter-modulation between output and IC.

UM66 has an inbuilt beat and tone generator.

Where can i buy Which is the nte datasheer. The melody will be available at pin 3 of UM66 and here it is amplified by using Q1 to drive the speaker. There is an inbuilt oscillator circuit that serves as a time base for beat and tone generator. The output of the IC that is the melody can be obtained at the pin BD pin3.
