It can also be easily interfaced with a normal Piezo electric speaker even buzzer or to a 6 ohm speaker through a NPN transistor as shown below. It has an inbuilt tone and a datashewt generator. We have other Tone Generator circuits that you may like; Take a look: The circuit can be made even without soldering and the ideal for the first electronic project for newbies.

If you get a distorted sound you can add uF electrolytic capacitor in parallel to C1. Powers the IC, typically with 3. Thanks for the CMOS technology.

We have already learnt how Zener can be used as Regulator and how the Zener resistor value R1 can be calculated. Connected to the ground of Circuit.

This is the simplest ever musical calling bell that can be easily built. The BT66T can operate only below voltage range 3.

The component details with cost is also with. Complete Technical Details can dafasheet found at the datasheet given at datasheeet end of this page. The details about the IC can be found here http: Interface GPS with Arduino. The speaker can be driven by an external npn transistor connected to the output of UM Arduino based GPS receiver.

It is better that you should not run this circuit. Connection Diagram The connection diagram is shown below.

Dear sir, could you forward me a 30second sound circuit that activated by another speaker out alarm clock Thanks shyaman. You need a voice recorder circuit interfaced with a amplifier circuit. Component Description IC and Transistor.

UM66 has an inbuilt beat and tone generator. Datahseet begins from the first note if power is reseted. C1 is used to decouple power supply to avoid inter-modulation between output and IC.
