However, explanation of the circuit? No matter how many times you press the key you can still hear the sound. As long as its input voltage exceeds a certain value, the operational amplifier will produce a signal.

As you have witnessed, there are many ways to make an oscillator. Are like one-way streets. When either terminal A or B is connected to terminal H the display shows L. Use terminals 83 and 84 and terminals 81 two different transistors – one of the two PNP types playgrounx Page of Go.

Elenco Electronics EP-130 User Manual

The schematic shows how it works. The resistors and capacitors in the twin-T network determine the frequency of oscillation. Follow the wiring sequence and observe the drawings.


This LED flasher uses two diodes. Table Of Contents Important: If you press the key, you hear a repeating sound from the speaker. By pressing ‘print’ button you will print only current page. Slide the switch to position 130-i-n1 and connect the wires for this circuit. If the output is 0, low then the input is 1 high.

When you yell, you create sound waves, which are actually variations in air pressure. This circuit uses three NAND gates and a multivibrator. After you complete the wiring, slide the switch to position A to turn on the power. This cylindrical component with a coil of created by variations of vibrations and then travel fine wire wrapped around it is a radio antenna.

Playbround you find what it is? This circuit is activated by light, so you can use it as an early bird wake up alarm. The key is a eleenco switch—you press it and electricity is allowed to flow through the circuit.

Elenco in-One Electronic Playground and Learning Center # EP

This experiment will show you how temperature affects transistor action. Here we have a multivibrator-type oscillator controlling a pulse oscillator. Inductor A component that opposes Electricity How does this work?

Clockwise In the direction in which the Alternating Current A current that is constantly hands of a clock rotate. Series When electrical components Oscillator A circuit that uses feedback to are connected one after the generate an AC output.


In this circuit, we will use an operational amplifier so you can hear the radio through the speaker. In our last two projects you have been shown how you are able to use NANDs to make up some ellenco logic circuits. You could create a game with this circuit. Attach the earphone to Terminals 13 and 14 and set the switch to position A.

Wake Up Siren To turn the circuit on, connect terminals 13 and From the schematic electroni can see that this experiment uses a combination of simple components and digital electronics. From looking at the schematic, can you explain how the circuit produces this sound? When the time is up, it gives out a continuous buzzer sound until you turn off the power or press the key to reset the circuit.
