Beginner guide to electrical components and description.

Electrical components are commonly found on circuit boards and their presence is ubiquitous in mordern engineering here are some lists of materials you need to be familiar at:

1.Capacitor

Symbol of capacitors.

It consists of two metals separated by a dielectric material,it is use for storing charges.types:

Ceramic, electrolytic,film and vairable capacitors.electrolytic is grouped into aluminum and tantalumcapacitor.Applications range from storing electric charge, stabilizing current, reducing riples in voltage and use in radio for tuning.

2.Diode

Diode symbol.

It is use for rectifying DC from ac since it only allows current in one direction,the part with white strip is the negative pole known as the cathode while the other black area is the positive side called anode.types of diodes:Zener,LED known as light emmiting diode, photodiodes,avalanche diode.

3.Transistors

Transistors.

it is basically used for amplification,switching, regulating and control it is made of semiconductors and has three pins or more,types: NPN and PNP,MOSFETs,FET etc.

4.Transformer.

Center tapped transformer.

It is commonly use for stepping up or down ac voltage,we have two types which are center tapped and the normal transformer.The center tapped transformer is usually use for making inverter.

5.Inductor.

Inductor.

It is use for stabilizing current and delaying current,it has no polarity,it is made by wounding copper wire on a ferrite bead.

Symbol of an inductor.

How to program an arduino with a smartphone.

H ow to program an arduino with a smartphone Before, we can only program an arduino with a laptop or desktop computer ,but most hobbyist doesn't can't afford to buy one but thanks to the new era of Technology we can now program our board with our smart phone any where we like and at any time.To program an arduino you need to download Arduino droid or arduino commander from the Google play store, I prefer arduino droid to Arduino commander because of it flexibility and ability to understand.To start coding with your phone you need a knowledge of c++ language,the Arduinodroid is both a compiler and an editor that is you can compile your skecth right after writing it. How to program with your smartphone . You will need an OTG cord to connect your Arduino to your phone for skecth uploading since the arduino cord can't directly connect to it.you can only use an android phone with version 2.0 or higher. When trying to upload your sketch the board will feed current from your phon...

How to make a powerbank with 9v battery.

Home made 9v power bank. U  In this article we will learn how to make a power bank for our phones in case of emergency,smartphone has became a very unique device in the life of men but the only problem is the power source to keep it running on.we have many diy power banks we can make like rechargeables,4000mah power bank,non rechargeables,hand driven charger etc.So let's cut our story shot and go straight to the point. Materials. 1.ic7805cv that is for regulating 9v_5v 2.old USB. 3.wires for connection 4.LED,.1k resistor,if you wish to add an indicator bulb. 5.9v battery. Circuit diagram below. good luck!!!!
