Monster Mouth A VOM or Kit, you can learn about electronics while doing multimeter is a instrument that measures voltage, fun experiments.

The electrical connection will not the numerous projects. Page 6 fine screen would keep rocks from falling over , which Capacitors: Capacitors move alternating current would prolong the flow of water but not stop it AC signals while prohibiting direct current DC completely. Like rocks are for water, resistors work in signals to pass. Page 7 Diodes: Are like one-way streets.

There are three prevent burning out the display with excess current, of these in your kit. Your kit contains one silicon diode permanent resistors have been wired in.

Page 8 Antenna: This cylindrical component with a coil of created by variations of vibrations and then travel fine wire wrapped around it is a radio antenna. If across the room. Page 9: Building Your First Project Key: The key is a simple switch—you press it and electricity is allowed to flow through the circuit. The key will be used in most circuits often times in signaling circuits you can send Morse code this way as well as other things.

Are you following the schematic diagram and the properly if you follow the wiring instructions. However, explanation of the circuit?

As your understanding if you do encounter a problem you can try and fix it by and knowledge expands of electronics, you will be using the following troubleshooting steps. Follow the wiring sequence carefully and observe the drawings. The simple circuit shown here does not have a key or a switch, but you can easily add one. This siren sounds like a real siren on a police car! After the wiring is competed press the key.

Then you Notes: might find this experiment helpful. This is an electronic version of the metronome, used by musical students and musical geniuses alike, worldwide. If you press the key, you hear a repeating sound from the speaker. Well not Notes: any longer, with this experiment you will make your own electronic grandfather clock. This circuit will produce clicks at approximately one- second intervals. The sound and timing together might remind you of an old grandfather clock.

Well that is just what you are going to be doing. How does this magic work? Well, the tones change based upon the amount of light that gets to the CdS cell. Follow the wiring sequence and observe the drawings. To finish the circuit below, slide the switch to the A position to turn on the power. You should try this next experiment to help you instead—see if the sound of this cat can keep the pests out of your life.

Just follow the drawing below and the wiring sequence. Due to research we are able to find out that some fish are attracted to certain sounds.

Instead the circuit will produce light with an LED. This will give you an idea of how larger strobe lights work. An Once you wire the project, use your special light FM radio signal is similar to this but at higher shield and your hand to change the light amount that It will make machine gun like sounds. This would be dangerous on a 0. After you close Notes: the key, the LED display shows 1 for a second and then turns off, even when you keep pressing the key.

You could create a game with this circuit. Display a number or a letter on the LED display and then have the players tell you what number it is. This experiment sounds as like a loud siren just like the real sirens on police cars and ambulances. The tone is initially high but as you close the key the tone gets lower. Page Ii. Basic Electronics Circuits II.

Try this project. After you finish the wiring, set key. This circuit is for Notes: entertainment. The numbers 1 and 2 will flash on the display in the circuit.

This might remind you of some neon signs that have eye-catching advertisements on them. Automobile ignition systems use a similar capacitor-discharge Notes: reaction.

The important rule to remember for transistors is: a transistor is turned on when a certain voltage is applied to the base.

A positive voltage turns on an NPN type transistor. The capacitors. They store electricity, smooth out pulsing higher-pitch sound is caused by the lower electricity into a steady flow and let some electric capacitance.

You will be using the key. Use terminals 83 and 84 and terminals 81 two different transistors - one of the two PNP types and You values. In an Notes: amplifier, a small signal is used to produce or control a large signal. This circuit is similar to an early model transistor hearing aid amplifier. Page Iii. What numbers and letters do you see displayed?

Think of the CdS cell as a resistor that changes its resistance based upon the amount of light that falls upon it. This circuit is similar to the one in Project 18 Transistor Action. The differences between these two are the position of the switch as well as the value of the resistor. Page Iv. A circuit that acts as a switch to A.

The lower part of the LED lights up. Press the to turn different components off and on is a digital key now. The base of the PNP transistor turns on when both When all the connections to its terminals are logic of the inputs are high and when both diodes supply high receiving voltage , the AND circuit produces a negative voltage to the base of the PNP transistor.

Are you able to Notes: guess how this circuit may work? In the OR circuit logic high is produced when A or B receives a logic high input. This term means inverted or Non-AND function. It creates output conditions that are the opposite of the AND circuits output conditions. When either terminal A or B is connected to terminal H the display shows L.

An exclusive OR abbreviated XOR circuit provides a high output only when one or the other of its inputs are high. You can see that an XOR circuit produces a low output, only if both of the inputs are the same high or low.

When the input to the of one as the input of another? If the output is 0, low then the input is 1 high. If the output is 1, then the input is 0. As you build this circuit, leave the switch at B. In our last two projects you have been shown how you are able to use NANDs to make up some other logic circuits.

As we Notes: mentioned earlier circuits that flip-flop alternate between two states.

With these all-in-one labs, you'll learn about electronic parts, how to read schematics, and wiring diagrams. All this while building up to different projects. These kits use two quick and easy hook-up methods: Spring Method: Simply slip pre-cut wires and components into special springs for a safe, secure connection. Breadboard Method: Featured in our advanced kits, this system is used by professionals and engineers. Just plug the components and wires into the special breadboard socket holes. No soldering is required.
