This IC is easy to use because it can work on low voltage 0. The melody will be available at og 3 of UM66 and here it is amplified by using Q1 to drive the speaker.

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

It has an inbuilt tone and a beat generator. The connection diagram is shown below. Like Admin has stated, UM66 is designed and manufactured with those melodies. This is the simplest ever musical calling bell that can be easily built.

Submitted by admin on 24 October This high-density System-in-Package SiP integrates controller, power switches, and lf components. Here the musical IC UM66 generates the music when it receives.

It is better that um666 should not run this circuit in Eliminator as most of the available eliminator don’t have a good filter built in and have no precision over voltage protection. It has a 62 notes ROM to play music. Choosing Battery for Robots. It is mainly used in circuits where a tone has to be played as a notification for the user.

Interface GPS with Arduino. You need a voice recorder circuit interfaced with a amplifier circuit. If anyone want to reduce the volume of the circuit then insert a resistance in place of the blue line connection.

Interface SD Card with Arduino. What is Web Browser. Connected to the ground of Circuit. The volume of the sound of this circuit is so much that it can be used as a calling bell.

In this circuit please don’t give the supply beyond 3 volt without. I think the explanation i gave is enough to understand the circuit. Complete Technical Details can be found at the datasheet given at the end of this page. In this circuit please don’t give the supply beyond 3 volt without modification as the IC may got damaged. Resistor R1 limits the base current of Q1 within the safe values.

These frequencies are a factor of the oscillator frequency. Your email address will not be published. Touch Controlled Musical Bell. A set of 4 bits controls the scale code while 2 bits control the rhythm code. Do not exceed 4.

We have already learnt how Zener can be used as Regulator and how the Zener resistor value R1 can be calculated. The BT66T can operate only below voltage range 3. UM66 is a 3 pin melody device. The circuit should not be run in Rechargeable. C1 is used to decouple power supply to avoid inter-modulation between output and IC.

Four beats of these can be selected. I will add a voice recorder circuit soon. Hello I cant get that circuit in digikey. The speaker is connected in series with the transistor so that the tone can be played in the speaker.
