With some basic mistakes just as in your circuit the beginners will get disheartened when there ckt doesn’t work. Quote and Order boards in minutes on https: Leave Open for Normal Operations. We can change the frequeccy by rotating the knob of variable resistor.

This voltage is called Breakdown Voltage or Zener Knee voltage. There should be a resistence of 1K. Log in or register to post Comment. It is generally used in alarms and catasheet. While UM66 have a limitation of generating only one sound, we have UM which is very jc and can generate four types of sound i. 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.

Hi buddy there is basic flaw in circuit.

All the diodes allow flow of current in only one direction forwardbut Zener diode can allow current in reverse direction if the voltage goes uum3561 a certain limit. Below is the table for 4 Playing modes, you can produce whatever sound you want. Get Our Weekly Newsletter! Log in or register to post Comment.

The zener diode is connected directly to the 9 volt supply. Get Our Weekly Newsletter!

UM Datasheet, PDF – Alldatasheet

UM Pin diagram and Pin description is given below, taken from its Datasheet:. We can change the frequeccy by rotating the knob of variable resistor. It has inbuilt oscillators and circuitry to produce the sounds, and only require one external resistor. It is generally used in alarms and toys. Zener Diode is just like the other diodes, with only one difference.

The zener diode is connected directly to the 9 volt supply. UM Pin diagram and Pin description is given below, taken from its Datasheet: With some basic mistakes just as in your circuit the beginners will get disheartened when there ckt doesn’t work.

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.

There should be a resistence of 1K. Hi buddy there is basic flaw in 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 is a low cost and low powered 8 pin IC. UM Pin diagram and Pin description is given below, taken from its Datasheet:.

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. While UM66 have a limitation of generating ym3561 one sound, we have UM which is very useful and can generate four types of sound i. While building circuits many times we need to generate sounds like a musical sound or some kind of u,3561 sound. Below is the table for 4 Playing modes, you can produce whatever sound you want.

It is a low cost and low powered 8 pin IC. As we have used 9v battery, so we have used Zener Diode 3.
