In the OR circuit logic high is produced when A or B receives a logic high input. This siren sounds like a real siren on a police car!

Elenco in-One Electronic Playground and Learning Center # EP

Your going to make a siren that gives out a sound with a variable pitch. The sound and timing together might remind you of 130-in1- old grandfather clock.

From looking at the schematic, can you explain how the circuit produces this sound? What are you hearing?

Instead the circuit will produce light with an LED. Meet Transistor-transistor Logic VI. Generally they do not perform well and limited to using and crystal earphone since they have no power source.

Call toll-free or e-mail us at: Comments to this Manuals Your Name. When you play learnlng musical instruments, you can use white noise, a normally useless noise, as a sound source. Place the AM radio close to the circuit since the signal can only transmitted a few feet.

In this experiment, we will make a single-power source, non-inverting microphone amplifier. Can you tell how the operation will be different?


This circuit is similar to the one in Pearning 18 Transistor Action. This experiment will show you how temperature affects transistor action. After you complete the wiring, slide the switch to position A to turn on the power.

Assemble the experiment, set the switch to position A, and see how this circuit works.

No part of this book shall be reproduced by any means; electronic, photocopying, or otherwise without written permission from the publisher. As you build this circuit, leave the switch at B. Playground 130-in1- Electronic Circuits I.

As you build this experiment, be sure to connect these diodes in the correct direction. Try to figure out how to connect a switch to the door of your house, so that the alarm sounds when a burglar opens the door, instead of stretching out the wire. Then the LED segments will light up Notes: Slide the switch to position B, and connect the wires carefully – this project is more intricate than most elecfronic the others.


Voice Activated LED The brightness electronci the LED in this circuit changes according to the level of voice input that comes from the microphone the earphone.

This is an ans version of the metronome, used by musical students and musical geniuses alike, worldwide. In this experiment, you will build an electric buzzer that makes a continuous beep. By pressing ‘print’ button you will print only current page.

This circuit is activated by light, so you can use it as an early bird wake up alarm. Basic Electronics Circuits II.

This LED flasher uses two diodes. How does this work?
