  Introduction to Project Nuggets of LEDs are used in making a three dimensional in making a 9x9x9 cube of the project at present uner consideration. The hefty arrangement of the project makes it beautifull in outlook and unique in construction. 729 LEDs in the construction kneeted together such as bricks play important role in construction of building.This projected selected by groups handpicked. It is opted by considering its utility, complexcity and beauty. The completion of this complex project was a danting task. Construction Project construction can be divided into two parts. • Hardware Construction • Software Construction 1 Hardware Construction The 3D LED cube is made up of 729 LED’s. There are large numbers of anode and cathode. LED cube consist up of rows and columns. Every LED cathode legs solder together in a row.All anode of LED are solder together in a column. Every column connected to the arduino board through separate wire. Every column might be control separately ....

  1 Resistences Electrical resistance is an opposition of current of an object flowing through it. We use resistences to safe our circuit and wires. 2 Soldering Iron Soldering iron is an instrument made up of a metal which gets heat up and transfer heat to electrical components like wires. 3 Connecting Wires Connecting wires permits current to transfer from one point to another in the circuit because electrical need a medium to move between two points.

    Arduino UNO Arduino is an original platform built on a stress-free to practice hardware as well as software. It comprises on circuit board which may be programmed as well as ready made software known as arduino integrated development environment (IDE), which can be use to upload and write computer code. The important features are: • Arduino board also known as controller board. • Controller boards are capable to read analog and digital inputs from various sensor and change it in output like blinkingLED’s. • We can control our board functions through sending different instruction to microcontroller on arduino board. • Arduino need no further part of hardware, unlike most important programmable circuit to load new code on the board. • Further arduino integrated development environment (IDE)uses a basic form of C++ , which making it easy to write programe. Different kinds of controllers are arduino boards are available on the market depending on various kinds of micro...

 1 Transistor  There are two types of transistors. • NPN Transistor • PNP Transistor NPN Transistor consist on three semiconductor materials in which two are N type and one is P type semiconductors.  There are three regions of NPN transistor.  • Emitter • Base • Collector (1) Emitter  The region to the one side of base is called emitter. It has greater concentration of impurity then collector. (2) Base  The central region is very thin of the order of 10-6m is called base.  (3) Collector  The region to the other side of base is called collector. It is larger than emitter. Both emitter and collector have large impurity concentration than base.  The arrow point on the emitter terminal shows the NPN transistor. We use NPN transistor in our project because it is most c ommonly and easy to deal with it.  2 LED LED stand for light emitting diodes.  Light emitting diodes are made from special semi-conductors such as gallium arsenide an...
