Doug Lowe has written a whole bunch of computer books, including more than 35 For Dummies books Networking for Screenwriting For Dummies (For. that careful supervision is given to children when working with mains powered electrical and electronic circuits and soldering irons. Thank you and take care. Electronics For Dummies. This book helps you out with that part, explaining the whole thing in plain English. Learn how electricity functions, how to harness it.
Read this first. It could save you money. More info Can be used with iPod etc.
Click HERE for info. How to use a multimeter Indispensible for the electronics hobbyist! By popular request this eBook has been written to explain the most basic uses of a multimeter with extensive use of photographs to show the methods in detail. There's nothing complicated in this eBook. It sticks to simple activities like checking batteries, resistors, diodes, fuses and capacitors; measuring voltage and current. Are you interested in an on-line Electronics Course? When you turn the shaft of a potentiometer the resistance changes in the circuit.
These are often found in exterior lights that automatically turn on at dusk and off at dawn. Capacitor Capacitors store electricity and then discharges it back into the circuit when there is a drop in voltage.
A capacitor is like a rechargeable battery and can be charged and then discharged. Diode A diode allows electricity to flow in one direction and blocks it from flowing the opposite way.
Light-Emitting Diode LED A light-emitting diode is like a standard diode in the fact that electrical current only flows in one direction. The main difference is an LED will emit light when electricity flows through it.
Inside an LED there is an anode and cathode. The longer leg of the LED is the positive anode side.
Transistor Transistor are tiny switches that turn a current on or off when triggered by an electric signal. In addition to being a switch, it can also be used to amplify electronic signals. A transistor is similar to a relay except with no moving parts.
Relay A relay is an electrically operated switch that opens or closes when power is applied. Inside a relay is an electromagnet which controls a mechanical switch.
This circuit contains electronic components like resistors and capacitors but on a much smaller scale. Integrated circuits come in different variations such as timers, voltage regulators, microcontrollers and many more.
What Is A Circuit? Before you design an electronic project, you need to know what a circuit is and how to create one properly.
An electronic circuit is a circular path of conductors by which electric current can flow. A closed circuit is like a circle because it starts and ends at the same point forming a complete loop. In contrast, if there is any break in the flow of electricity, this is known as an open circuit.
All circuits need to have three basic elements. These elements are a voltage source, conductive path and a load.
The voltage source, such as a battery, is needed in order to cause the current to flow through the circuit.
In addition, there needs to be a conductive path that provides a route for the electricity to flow. Finally, a proper circuit needs a load that consumes the power. The load in the above circuit is the light bulb.
Schematic Diagram When working with circuits, you will often find something called a schematic diagram. These symbols are graphic representations of the actual electronic components. Below is an example of a schematic that depicts an LED circuit that is controlled by a switch.
It contains symbols for an LED, resistor, battery and a switch.
By following a schematic diagram, you are able to know which components to use and where to put them. These schematics are extremely helpful for beginners when first learning circuits. Below are a few of the most commonly used electronic symbols in the US.
To find the resistor value, you need to know the voltage and the amps for your LED and battery.
