Uploaded by: GLADIS The Conscious Parent. A Compilation of 21 tested Electronic Construction Projects and 71 Circuit Ideas. PDF | This Book is written for all the people who love innovation. It is the big collection of ideas to do some innovative project, to make. Use this book to build electronics projects involving circuits on a solderless breadboard. Electrical Engineering Basic Circuits (PDF). Build a circuit to make lights.

How to use the book Know the basics—To start working with electronics circuits ad projects, one should be very well aware about all basic electronic components like Resistor, capacitors, transitors etc. It is important to know how the components behave when they are connected in a closed circuitfor example—The purpose of a capacitor is to store charge and once charged capacitors cut off current supply through them. It is also important to understand what voltages should be applied to different components and the direction these components should be connected. For example—capacitors have a maximum possible permisable voltage rating along with polarity written on them , for resistors polarity doesnt matter. For most of electronics components manufactured today a voltage of around 5 volt is sufficient.

Apart from this circuit there are two more fundamentals on which touch circuits workResistive and capacitive. Both of these techniques are used in touch mobile.

In resistive touch screen a finger touch passes current between two tightly spaced invisible resistors on screen. Same happens in capacitive Where capacitors are used instead of resistors.
