Melody Generator using IC UM66

The BT66T can operate only below voltage range 3. In this circuit please don’t give the supply beyond 3 volt without.

Touch Controlled Musical Bell. This is the simplest ever musical calling bell that can be easily built. The beat generator is also a programmed divider which contains 15 available beats. The circuit should not be run in Rechargeable.

Do remember that this IC will be able to play only one tone, if you need a different tone you have to use a different IC with datazheet different part number as shown above. Many versions of UM66T are available which generate tone of different songs. Assemble the circuit on a good quality common board.

Skip to main content. The tone generator is a programmed divider which produces certain frequencies. I will help you. This IC, datashwet its three legs, looks like a transistor.

It is mainly used in circuits where a tone has to be played as a notification for the user. This high-density System-in-Package SiP integrates controller, power switches, and support components.

Basically, the output pin pin 3 turns on and off in a particular fashion to provide the tone. You need a voice recorder circuit interfaced with a amplifier circuit.

Component Description IC and Transistor. The details about the IC can be found here http: Interface GPS with Arduino.

Capacitor C1 is meant for noise suppression. Connected to the ground of Circuit. Submitted by admin on 24 October Ding Dong Sound Generator. It can also be easily interfaced with a normal Piezo electric speaker even buzzer or to a 6 ohm speaker through a NPN transistor as shown below.

The device has very low power consumption. It has a built in ROM programs for playing music. This is a simple project using the IC UM Powers the IC, typically with 3.

Where can i buy Which is the nte replacement. It is better that og should not run this circuit. It has an inbuilt tone and a beat generator.

The circuit can be made even without soldering and the ideal for the first electronic project for newbies. Thanks for the CMOS technology. Previous post Next post.

It is designed datashfet use in bells, telephones, toys etc. The output of the IC that is the melody can be obtained at the pin BD pin3. Is capacitor helps in sound suppression in this circuit?

Interface SD Card with Arduino. These frequencies are a factor of the oscillator frequency. Data sheet of UM66 is there in the datasheet section of the dayasheet. The connection diagram is shown below.

Melody begins from the first note if power is reseted. It is not possible to store our own music in UM Resistor R1 limits the base current of Q1 within the safe values. Complete Technical Details can be found at the datasheet given at the end of this page. The component details with cost is also with.
