Leave Open for Lc Operations. Zener Diode is just like the other diodes, with only one difference. Hi buddy there is basic flaw in circuit.

While building circuits many times we need to generate sounds like a musical sound or some kind of alerting sound.

All the diodes allow flow of current in datasbeet one direction forwardbut Zener diode can allow current in reverse direction if the voltage goes beyond a certain limit.

Quote and Order boards in minutes on https: Leave Open for Normal Operations. UM Pin diagram and Pin description is given below, datashheet from its Datasheet:. There should be a resistence of 1K.

As we have used 9v battery, so we have used Zener Diode 3. UM works in the range of volts, voltage higher than 5V can damage the IC, so if we are using it with other circuit or using a high voltage source, a Zener diode must be connected, to protect the IC.

The output generated by the IC is not sufficient to drive a 8ohm small speaker, so to amplify the output of the IC, a transistor must be used at the output PIN 3. Log in or register to post Comment. Below is the table for 4 Playing modes, you can produce whatever sound you want.

All the diodes allow flow of current in only one direction forwardbut Zener diode can allow current in reverse direction if the voltage goes beyond a certain limit. UM works in the range of volts, voltage higher than 5V can damage the Dztasheet, so if we are using it with other circuit or using a high voltage source, a Zener diode must be connected, to protect the IC.

While UM66 have a limitation of generating only one sound, we have UM which is very useful and can generate four types of sound i. With some basic mistakes just as in your circuit the beginners will get disheartened when there ckt doesn’t work. Hi buddy there is basic flaw in circuit. With some basic mistakes just as in your circuit the beginners will get disheartened when there ckt doesn’t work.

The zener diode is connected directly to the 9 volt supply. As we have used 9v battery, so we have used Zener Diode 3. While UM66 have a limitation of generating only one sound, we have UM which is very useful and can generate four types of sound i.

We can change the frequeccy by rotating the knob of variable resistor. U should be careful while drawing the circuit.

The output generated by the IC is not sufficient to drive a 8ohm small speaker, so to amplify the output of the IC, a transistor must be used at the output PIN 3.

It has inbuilt oscillators and circuitry to produce the sounds, and only require one external resistor. It is generally used in alarms and toys.
