We have other Tone Generator circuits that you may like; Take a look: Submitted by admin on 24 October The volume of the sound of this circuit is so much that it can be used as a calling bell.
The speaker can be driven by an external npn transistor connected to the output of UM When power is turned on, the melody generator is reset and melody begins from the first ym66. Capacitor C1 is meant for noise suppression. Choosing Battery for Robots. Is capacitor helps in sound suppression in this circuit?
UM66 Datasheet, PDF – Alldatasheet
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. Do not exceed 4. The datasjeet can be made even without soldering and the ideal for the first electronic project for newbies. Skip to main content. Virgin Galactic — Commercial Space Flight.
The part number and its respective tone is mentioned in the datsheet below, you can Google the tone name to listen to the type of tone the IC will play. Data sheet of UM66 is there in the datasheet section of the site.
The component details with cost is also with. It has an inbuilt tone and a beat generator. The BT66T can operate only below voltage range 3.
This project is suitable for beginners as its circuit is very simple. Here the musical IC UM66 generates the music when it receives. SPI Module of Arduino.

Dear sir, could you forward me a 30second sound circuit that activated by another speaker out alarm clock Thanks shyaman. It is mainly used in circuits where a tone has to be played as a notification for the user.
Ov email address will not be published. It is better that you 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. As mentioned in the features, the BT66T comes in five different part numbers.
Thanks for the CMOS technology. Many versions of UM66T are available which generate um666 of different songs. This IC, with its three legs, looks like a transistor. Connection Diagram The connection diagram is shown below.
What can be done to strengthen the multiplier circuit?
This is the output pin, where tone is generated. I will help you.

Component Description IC and Transistor. The details about the IC can be found here http: The component details with cost is also with this. The circuit should not be run in Rechargeable battery also if the Speaker resistance is less than 8 Ohm and may burn the Transistor. Interface SD Card with Arduino. You need a voice recorder circuit interfaced with a amplifier circuit. Connected to the ground of Circuit. The tone ij is a programmed divider which produces certain frequencies.
I will add a voice recorder circuit soon. Hello I cant get that circuit in digikey. Basically, the output pin jm66 3 turns on and off in a particular fashion to provide the tone.
C1 is used to decouple power supply to avoid inter-modulation between output and IC. The melody will be available at pin 3 of UM66 and here it is amplified by using Q1 to drive the speaker. What is Web Browser. This IC is easy to use because it can work on low voltage 0. Leave a Reply Cancel reply Your email address will not be published. You can not reprogramme it.
Complete Technical Details can be found at the datasheet given at the end of this page. We have already learnt how Zener can be used as Regulator and how the Zener resistor value R1 can be calculated.
