Guide For Summer Training in Delhi For CSE

CSE students often get confused about what are the most suitable  options for summer training in Delhi for CSE students.

” Should I learn JAVA ? or should I stick with the basics C, C++ ?

Should I go for Android App Development ? or should it be PHP ? “

All these questions boggle a CSE student and he/she often ends up taking an incorrect decision. All the queries related to the right summer training in Delhi for CSE students will be addressed here.

The most popular training options among CSE students are:

  1. JAVA
  2. Android App Development
  3. .Net
  4. Cloud Computing

The correct way to select the best suited course is to first evaluate your knowledge and then see that do you still need to clear your basics or are you ready to pursue advanced level courses.

Summer Training programs for CSE students that will help you strengthen your basics

  • PHP and MySQL Training : Almost 95% of the engineering students complain about their weak programming skills. PHP and MySQL have the power to develop your core skills and prepare you for advanced levels. PHP will strengthen your programming skills while My SQL shall help you understand databases in a better way. PHP is widely used for developing websites and online applications.

WARNING: B Tech students have been underestimating the power of PHP for a very long time now. The myth among them is that the language is only meant for BCA students. This misconception needs to be erased from the minds of these students and they need to understand the fact that PHP is the one language which will develop their programming basics like never before. PHP teaches you how to use internet from a PRO’s perspective.

  • C and C++ Training : This is the most basic programming language and has been around for the past 4 decades.  Learning these will surely help you understand programming but C has become obsolete over the years and may prove to be boring to learn. The variety of summer training projects that a student can undertake is limited due to this the overall programming skill of the student might remain weak as this language is unable to generate sufficient interest and motivation for the student.

Intermediate level summer training in Delhi for CSE students

  • JAVA Training : This is one of the favorite programming language of IT industry. The Language is based on the concept of OOPS and exhaustively utilizes classes and data encapsulation to write programs. JAVA is a complex language and hence, not suitable to clear your programming basics.

WARNING: The students who have a fear of programming should never take up JAVA as their   first time programming language. If tried they might end up wasting their time and money.A CSE student would need to take up this summer training course at some point in his/her career but preferably only after mastering PHP or C, C++

  • ASP.Net Training : It is another programming language that is widely used for commercial software development. This is also an intermediate level course and it is advisable that it should not be taken up before clearing out the basics.

You may choose between JAVA or .Net but as far as our advise is concerned JAVA is always a better option for students in terms of learning prospects as one can easily extend the knowledge of JAVA to app development.

Expert advice to CSE students looking for summer training

Being a B Tech CSE student they have to realize that you cannot give any justifications for your poor programming skills. Saying ” Mujhe programming nahi aati ” is a lame excuse and can prove to be fatal for your career. It will take 6 months of dedicated work and you will become a programming superstar.

Blaming the trainers and teachers for your under developed skills is not going to build your career. The effort you put in your studies is what matters and is what will build your pathway to success.

Robotic Hand Using Arduino Tutorial

The robotic arm apes the movement of an actual human hand. There are dedicated flex sensors for each finger. Each mechanical finger moves according to the input from the corresponding flex sensor. This mechanism can be used not only for the robotic hand but to control any appliance using hand gestures. Here is a  crisp tutorial for the robotic hand using Arduino.

Materials Required:

  • Arduino Uno
  • Five servo motors (Preferably Vigor)
  • Five flex sensors
  • Some 10 K resistances
  • Some 1K resistances
  • Three 7805 ICs (With heat sinks)
  • Four 2007 diodes
  • Burg sticks
  • Three good quality PCBs
  • Five meters ribbon wire
  • Five Optocouplers
  • Four 1000 micro Farad capacitors
  • Flexible plastic drainage pipe
  • A small piece of ply board
  • Fishing Wire
  •  A customized metal cover (optional)

Step -1

Flex sensors are quiet sensitive and get damaged easily. Solder only the tips and not a millimeter extra. Length of connecting wires should be at least 2 meters.  Now connect single pin connectors to the other ends of wires.

Step – 2

Create a high current capacity power supply by using three 7805s in parallel. You may also use any other voltage regulator with higher current capacity for me 7805s worked just fine.

Step – 3

Flex sensors are variable resistors who’s resistance varies as the sensors are bent. One can easily create a potential divider circuit and convert the variable resistance to variable voltage.

DIY Motion Sensor Light Switch Tutorial

In this post we shall make a simple and a cheap DIY motion sensor light switch. We haven’t made use of any microcontroller or any other complex circuitry. This module can be easily developed by almost everybody.

You would require the following parts to create this DIY motion sensor light switch:

  • A PIR Motion sensor
  • A 7A, 12v relay
  • A NPN transistor (BC 547)
  • Burg sticks
  • 7805 Voltage regulator IC
  • A 12 v, .5 A -DC adapter
  • A 10 K resistor
  • A LED
  • Some connecting wires

Step 1

Most of the DC adapters available in the market are screw less and can be easily opened. Take the inner power supply circuit out of the DC adapter and identify the AC input and DC output pins. Since we have used a 12v adapter for our Motion sensor lights, the DC output would be 0v at -ve and 12v at the +ve terminal.

Step 2

Use the 12 v output from the power supply to act as an input to the 7805 voltage regulator IC.

You may refer to the image given above for making connections. We get a regulated 5 v supply between the ground and the output pin of 7805. In order to be sure you may check the 5v output using a multi meter.

Step 3

Create a relay driver using the BC 547, NPN transistor.

The 10k resistor goes at the base of transistor. Now manually connect the free end of the 10K resistor to 5v supply and listen for a tic-tic sound from the relay, this sound verifies the proper functioning of the circuit.

Step 4

Open the PIR Motion sensor (HC-SR501). This sensor works at 5v. and has three pins – Vcc, Gnd and Out.

Power the motion sensor and check its working by attaching a LED between its Out and Gnd pins.

Step 5 – Let’s assemble our DIY Motion Sensor Light Switch

Connect these parts in the following order and your DIY Motion Sensor Light switch is ready to ROCK !!

Note: The PIR sensor may take up to 45 seconds to warm up , so don’t panic if the sensor doesn’t work immediately after turning it on.
