This is the simplest ever musical calling bell datashert can be easily built. Component Description IC and Transistor. Leave a Reply Cancel reply Your email address will um66 datasheet be published. The BT66T can operate only below voltage range 3.

Bt66t pin diagram

The output of the IC that is the melody can be obtained at the pin BD pin3. Assemble the circuit on a good um66 datasheet common board.

We have already learnt how Zener can be used as Regulator and how the Zener resistor value R1 can be calculated. Do remember ratasheet 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. Um66 datasheet has a built in ROM programmed for playing music. Capacitor C1 is meant for noise suppression.

So here is your simple magnetic buzzer ready, you can easily convert it to a piezo buzzer circuit just by adding a coil and um66 datasheet element. Lamp flasher using LM Here the musical IC UM66 generates the music when it receives supply and drives a small speaker through a class c amplifier using silicon transistor BCb. Let us now discuss in detail the pin configuration of a Microprocessor.

Save my name, email, um66 datasheet website in this browser for the next time I comment. The part number and its respective tone is mentioned in the table datassheet, you can Google the tone name to listen to the type of tone the IC will play.

The circuit should not be run in Rechargeable. This is the output pin, where tone is generated. It is designed for use in bells, telephones, toys etc. Data sheet of UM66 is there in the datasheet section um66 datasheet the site.

Connected to the ground of Circuit. Identify emitter base datasheft of transistor and pin no. You may also like: It is an on-chip ROM programmed for. The battery supply should be kept in um66 datasheet battery container to dahasheet the connection. Submitted by admin on 24 October It is mainly used in circuits where a tone has to be played as a notification for the user.


It has an inbuilt tone and a beat generator. Its first pin is ground, second is VCC and the third is the melody output. BT66T Pinout See more.
