India Successfully Tested Upgraded Pinaka Rocket

An upgraded version of pinaka rocket was successfully test fired from the Proof & Experiment Establishment (PXE) at chandipur in odisha. The rocket is upgraded with a guidance system and it's range is also increased.

A defense source said that two round of tests have been conducted and some more rounds have been planned.The prior pinaka rocket was an unguided one,but now it has been upgraded into a guided version,with a navigation,guidance and control kit.

Source from DRDO said that,this conversion helped in enhancing the accuracy and range of pinaka. Earlier version of pinaka has range of 40 km but now upgraded version has range of 70 km.

Mahindra and Boeing came together to make F/A-18 fighters in India

India's Mahindra Defense System (MDS) has signed a deal with US aircraft maker Boeing to make F/A-18 super hornet jets in India. Hindustan Aeronautics will also participate.

Mahindra Defense System (MDS) up to now has made noncombat defense equipment such as armed vehicles and radar systems.

Details such as how many fighters will be build,cost of the project and when and where production will start is not disclosed yet.Partners said they will make fighters for India, in India.They also said they will also cooperate on research and development.

A source from mahindra said that, the company will initially supply fighter for indian armed force and later may export.The roles of the companies is not defined yet but a mahindra executive said that Boeing will give license for technology, Hindustan aeronautics will be main assembler and Mahimdra defense system will make components of aircraft.

IF Statement

The if statement is the first control structure.Here is an example of a programming using it:

        

                                                                listing 1.1: blink_if

int delayTime = 1000;

There is no const keyword because this is not a constant.It is a variable(which means its value can change or vary during the program).

delayTime = delayTime - 100;

Here we are changing the value of delayTime by subtracting 100 from it's original value.Since original value was 1000,after this happens the new value will be 900.

if(delayTime <= 0)

{

delayTime = 1000;

}

The purpose of this selection is to make sure the light always blinks.Since we are subtracting 100 from delayTime, we want to keep it from becoming 0 or negative.

The last section of programming turns the led on and off.

India Tested Indigenous Engine to Power UAVs in the Himalayas

Indian scientist have successfully tested a prototype of small turbofan engine named "manik" at Leh situated at an altitude of above 11600 ft.This is part of high altitude cold climate trials.It was started in February this year.

The design,selection of materials and the control logics used for lightning and acceleration of the engine to a minimum speed are validated by this successful test.

As IAF (Indian Airforce) is looking for UAVs (Unmanned Aerial Vehicles) that can operate in high altitude,the successful test of 450 kg thrust class engine is great achievement.

Using a Pushbutton to Control the LED

Blinking an LED was easy,but i don't think you would stay sane if your desk lamp were to continuously blink while you were trying to read a book. Therefore, you need to learn how to control it.

In this case we are going to use simplest form of sensor available:a pushbutton.

digitalRead() checks to see whether there is any voltage applied to the pin that you specify between parenthesis,and returns a value of HIGH or LOW depending on finding.

The if statement is possibly the most important instruction in a programming language,because it allows the computer to make decisions.After the if keyword, you have to write a question inside the parenthesis, and if the answer or result is true, the first block of code will be executed and if answer or result is false then else part will be executed.

BrahMos Missile to Attain Mach 7 in Next Decade

BRAHMOS MISSILE

Latest Defence News

Brahmos,the fastest cruise missile in the world will achieve mach 7 speed to become a 'hypersonic' missile in the next decade, a top official said.

Sudhir Mishra,the chief executive and managing director of the joint venture company Brahmos aerospace told that they will require seven to ten years from now to make a hypersonic missile system.

He also said that Brahmos which currently has speed of mach 2.8,will touch 3.5 soon and mach 5 in three years.

The current engine will have to replace to achieve mach 5.

He said different indian institutions such as DRDO, IITs and IISC and Russian institutes are working on technologies whic will help to achieve the goal.

In recent time,Brahmos has been modified in such a way that it can be launched from different platform.

ARDUINO BASICS:-

A tutorial for the beginners

  First thing we need the Arduino IDE software to compile the code which also can upload it to the Arduino.So lets start our first programming that is Blinking an LED.

The LED blinking sketch is the first program that you should run to test whether your arduino board is working and is configured correctly.It is also usually the very first programming exercise someone does when learning to program a microcontroller.An LED has two terminal,longer one is positive and shorter one is negative.Once the LED is connected,you need to tell Arduino what to do.This is done through code,that is a list of instructions that we give the microcontroller to make it do what we want.

On your computer,go open the folder where you copied the Arduino IDE.Double click the Arduino IDE icon to start it.Select File>New and you'll be asked to choose a sketch folder name:this is where your Arduino sketch will be stored.Name it Blinking_LED and click OK.Then type the code(Example 01) into the Arduino sketch editor(the main window of the Arduino IDE).

Now that the code is in your IDE, you need to verify that it is correct.Press the "verify" button.If everything is correct, you'll see the message "Done compiling" appear at the bottom of the Arduino IDE.This message means that the Arduino IDE has translated your sketch into an executable program that can be run by the board.
At this point,you can upload it into the board:press the upload button.This will reset the board,forcing it to stop what it's doing and listen for instruction coming from the USB port.The Arduino IDE sends the current sketch to the board,which will store it in its memory and eventually run it.
