1) ARDUINO UNO

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike.

2) MATRIX

What is LED matrix? Led matrix is a dot matrix of large display, low resolution value and is useful for both industrial or commercial displays as well as for hobbyist human interface machines. In contains a 2-D diode matrix which have the cathode joined in rows and anode in columns. In this LED matrix each can be control individually by controlling the electricity through each pair of columns or rows diodes. These matrix are very popular matrix by means of displaying information it, allows the static and animated images and text. A LED matrix is shown in figure.

Types of LED Matrix:

There are so many types are LED matric have been used for industrial and commercial purposes, some of which are discussing in this article with respect to structure.

8*8 dot Matrix
5*7 dot Matrix
128*16 Two lined
128*32 Four lined
128*64 Eight lined

8*8 dot Matrix:

In dot matrix multiple diodes are connecting together in rows and columns, this is done to minimize the number of pins required to drive the dot light emitting diodes. Suppose in 8*8 dot matrix there would be 64 I/O pins for displaying each

diode pixel. For making 8*8 dot matrix all the anodes are connecting together in rows R1 to R8, similarly the cathodes are connected together in columns C1 to C8, by doing this the required number of I/O pins have reduced by 16 shown is below:📷

According to the figure each LED is addressed to its row and column number. If R5 is pulled high and C4 pulled low, then the LED in fifth row and fourth column would be high, similarly the characteristics can also be displayed by scanning of each row and column.

5*7 dot Matrix:

A 5*7 LED matrix have 5 rows and 7 columns of light emitting dioses, which are connecting together for making this shown is figure in 3. According to the figure we want to display an alphabet word A then first we pulled high the column C1 and pulled low the other columns by blocking their ground paths. Now the C1 is pulled high and need to turn on the LEDs of rowsR2 to R7 of this column. This is done by the applying the forward bias voltage to these rows. Next select the column C2 and deselect the other column and apply the forward bias voltage across R1 and R5, and so on.

Construction of dot Matrix:

The construction of this display is very simple if you want to make your own prototype display then the diodes are just solder on Vero board or premade double or single sided board. Suppose we want a construct a prototype 8*8 dot matrix display shown in figure 2, then we have required 64 light emitting diodes. These diodes are solder on overboard or single sided board. The positive end of one diose is connected to other positive end of the diode for making the rows, similarly the 8 rows are made by connecting the positive end of each diode. The negative end one diode is connected to the negative end of other diode. For making the columns of this display, similarly the 8 columns are made by connecting the negative end of each diode. All these diodes are connected with each other through bare copper wire and all these are should be properly sold otherwise there would be no connection between all these.

Dot Matrix Interfacing with Microcontroller:

The dot matrix display consists of rows and columns, in these rows and columns LEDs are connecting. These can be on or off as wish, but this can be only done through microcontroller. Here we will interface pic microcontrollerswith dot matrix display shown in figure.

3) BLUETOOTH MODULE

Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves In the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks (PANs). It was originally conceived as a wireless alternative to RS-232 data cables.

HC-05 module Information

HC-05 has red LED which indicates connection status, whether the Bluetooth is connected or not. Before connecting to HC-05 module this red LED blinks continuously in a periodic manner. When it gets connected to any other Bluetooth device, its blinking slows down to two seconds.
This module works on 3.3 V. We can connect 5V supply voltage as well since the module has on board 5 to 3.3 V regulator.
As HC-05 Bluetooth module has 3.3 V level for RX/TX and microcontroller can detect 3.3 V level, so, no need to shift transmit level of HC-05 module. But we need to shift the transmit voltage level from microcontroller to RX of HC-05 module.
