TL — Programmable Reference Voltage. The battery supply should be kept in a battery container to ensure the connection. This Uum66, with its three legs, looks like a transistor. You may also like: What is Web Browser. It has an inbuilt tone and a beat generator. Four beats of these can be selected.

Melody Generator using IC UM66

We have already learnt how Zener can be used as Regulator and how the Zener resistor value R1 can be calculated. You need a voice recorder circuit interfaced with a amplifier circuit. Arduino based GPS receiver. In this circuit please don’t give the supply beyond 3 volt without.

If you get a distorted sound you can add uF electrolytic capacitor in parallel to C1. Whistle to Beep Circuit. The volume of the sound of this circuit is so much that it can be used as a calling bell. Resistor R1 limits the base current of Q1 within the safe values. C1 is used to decouple power supply to avoid inter-modulation between output and IC.

UM66 has an inbuilt beat and tone generator.

Where can i buy Which is the nte datasheer. The melody will be available at pin 3 of UM66 and here it is amplified by using Q1 to drive the speaker. There is an inbuilt oscillator circuit that serves as a time base for beat and tone generator. The output of the IC that is the melody can be obtained at the pin BD pin3.

The BT66T can operate only below voltage range 3. Touch Controlled Musical Bell. The details about the IC can be found here http: The device has very low power consumption. The circuit can be made even without soldering and the ideal for the first electronic project for newbies. This is a simple project using the IC UM This is the simplest ever musical calling bell that hm66 be easily built.

When power is turned on, the melody generator is reset and melody begins from the vatasheet note. What can be done to strengthen the multiplier circuit?

The connection diagram is shown below. These frequencies are a factor of the oscillator frequency. This high-density System-in-Package SiP integrates controller, power switches, and support components. Submitted by admin on 24 October
