In this basic undertaking we are going to make a tune generator circuit utilizing the IC UM66. This ic (UM66) has an inbuilt beat and tone generator.Tune GENERATOR  It has three legs like a transistor. This IC (UM66) has numerous forms with various sounds.GENERATOR Use IC This circuit is valuable for the fundamental side interest understudies

UM66 tune genrator icDescription 


The UM… .. arrangement are intended for utilizing in calling ringer, phones and toys. It has a worked in ROM programs for music. This gadget has low force utilization. The song is produced at pin 3 of UM66 IC and here it is enhanced by utilizing transistor (T1) to drive the speaker. This can create music without transistors however voice will b low. Resistor R1 limits the base current of T1 inside the protected qualities. Capacitor (C1) is intended for commotion concealment.

Precautionary measures

Try not to surpass 4.5 V. Force supply must be between 1.5V and 4.5V.

For noisy song Speaker can be driven with outer NPN transistor.

Song starts from the first if power is reset.

For better outcome circuit ought to be on a decent quality normal board.

Song can be producedTune GENERATOR  without transistor.

Parts

Capacitor 1uF 16v

UM66 IC

Speaker/signal

Resistor 4.7k

Force supply – 1.5-4.5V DC

BC 547 or any NPN transistor

Circuit Diagram without Transistor

The circuit can be utilized with no additional transistor. Music can be produced utilizing the ic. In any case, transistor is utilized to make song in noisy voice. The circuit Diagram with no transistor is given beneath.

Circuit Diagram

In this circuit we have utilized additional transistor and regularly utilized transistor.

Tune or Melody Generator Circuit utilizing IC UM66TXX

Working Of Melody Generated Circuit 


The working of the circuit is extremely straightforward. We have utilized UM66 a Happy Birthday Tone Generator IC in the circuit and you can change with some other ICS in the given beneath list. The working voltage of the circuit is around 1.5 to 4.5v DC,Tune GENERATOR  GENERATOR Use IC We have utilized a 3v battery to control the circuit given previously.

Yield of this IC was then nourished into the base of the transistor BC547 to drive the speaker associated with the gatherer of the TransistorT1. Here a Transistor BC547 works fine and a R1 4.7k resistor is utilized to restrain the current to the base of the transistor T1.

IC UM66TXX SERIES: 


The UM66TXX arrangement is planned explicitly for produce song, tone age circuits. It comprises of a chip ROM customized with a specific or tone. The IC UM66TXX devours low force since it was created by CMOS innovation. Last two digits of ic indicated tone/tune. The rundown of some regular tone generator IC and their comparable numbers.
