UM66 Datasheet, PDF – Alldatasheet

It is designed for use in bells, telephones, toys etc. The melody will be available at pin 3 of UM66 and here it is amplified by using Q1 to drive the speaker. The component details with cost is also with. Powers the IC, typically with 3.

Do not exceed 4. Ding Dong Sound Generator.

The BT66T can operate only below voltage range 3. Touch Controlled Musical Bell. Skip to main content. The circuit should not be run in Rechargeable battery also if the Speaker resistance is less than 8 Ohm and may burn the Transistor. 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 a different part number as shown above. Connected to the ground of Circuit.

The details about the IC can be found here http: You need a voice recorder circuit interfaced with a amplifier circuit. This is the output pin, where tone is generated.

C1 is used to decouple power supply to avoid inter-modulation between output and IC. Assemble the circuit on datasueet good quality common board. This IC is easy to use because it can work on low voltage 0. The circuit can be made even without soldering and the ideal for the first electronic project for newbies.

When power is turned on, the melody generator is reset and melody begins from the first note.

This is the simplest ever musical calling bell that can be easily built. Interface GPS with Arduino. This is a simple project using the IC UM Is capacitor helps in sound suppression in this circuit? Many versions of UM66T are available which generate tone of different songs. The volume of the dataseet of this circuit is so much that it can be used as a calling bell.
