Below is the table for 4 Playing modes, you can produce whatever sound you want. Log in or register to post Um3651. Quote and Order boards in minutes on https: There should be a resistence of 1K. Leave Open for Normal Operations. As we have used 9v battery, so we have used Zener Diode 3.

It is a low cost and low powered 8 pin IC. The zener diode is connected directly to the 9 volt supply. 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.

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. 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.

UM Pin diagram and Pin description is given below, taken from its Datasheet: UM works in the range of volts, voltage higher than 5V can lc 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.

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. It is a low cost and low powered 8 pin 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.

This voltage is called Breakdown Voltage or Zener Knee voltage. U should be careful while drawing the circuit. While building circuits many times we need to generate sounds like a musical sound or some kind of alerting sound. Zener Diode is just like the other diodes, with only one difference.
