It is designed for use in bells, telephones, toys etc. It is better that you should not run this circuit.
UM66 IC Datasheet | Melody IC Pin Diagram
We connect this output to the Base of BC which datasheeh also switch on and off in the same tone. This IC is easy to use because it can work on low voltage 0. The component details with cost is also with this.
The output of the IC that is the melody can be obtained at the pin BD pin3. Previous post Next post.
UM66 Datasheet, PDF – Alldatasheet
This high-density System-in-Package SiP integrates datashert, power switches, and support components. When power is turned on, the melody generator is reset and melody begins from the first note.
I think the explanation i gave is enough to understand the circuit. You need a voice recorder circuit interfaced with a amplifier circuit.
UM66T is a melody integrated circuit. The part number and its respective tone is mentioned in the table below, you pf Google the tone name to listen to the type of tone the IC will play.
TL — Programmable Reference Voltage.
Like Admin has stated, UM66 is designed and manufactured with those melodies. Connection Diagram The connection diagram is shown below. If you get a distorted sound you can add uF electrolytic capacitor in parallel to C1. Assemble the circuit on a good quality common board.
Connected to the ground of Circuit. It is mainly used in circuits where a tone has to be played as a notification for the user. 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.
Arduino based GPS receiver. The tone generator is a programmed divider which produces certain frequencies. It has an inbuilt tone and a beat generator. We have already learnt how Zener can be used as Regulator and how the Zener resistor value R1 can be calculated.
Melody begins from the first note if power is reseted. The battery supply should be kept in a battery container to u,66 the connection.

The speaker can be datashset by an external npn transistor connected to the output of UM The circuit should not be run in Rechargeable. Choosing Battery for Robots. Whistle to Beep Circuit. Leave a Reply Cancel reply Your email address will not be published.
Choosing Motor For Robots. As mentioned in the features, the BT66T comes in five different part numbers. I have searched for icum66 in the market but cannot find one.
SPI Module of Arduino. Submitted by admin on 24 October This project is suitable for beginners as its circuit is very simple.
Interface SD Card with Arduino. Thanks for the CMOS technology. Each part number has the capability to play a different type of tone. C1 is used to decouple power supply to avoid inter-modulation between output and IC. I will add a voice recorder circuit soon.
