Arduino Tutorials

Hello Friends, As we all know that Arduino is the open source electronics prototyping platform. Here are some of the tutorial for Arduino.
1. Blinking LED
Steps:

• Double click on Arduino icon. ( You can download Arduino From www.arduino.cc)
• Select File> New
• Give the folder name Blink_LED and click OK.
• Type the code as  given in pdf at end of this post in main window of Arduino IDE.
• Now you have to verify this code(ctrl+R).
• If your code is correct then press upload to I/O board button.( as shown in fig)
• When you see done uploading at the bottom then you have completed correctly.
• your LED will be blinking.

You can do many other tutorial as given in the below pdf file. For more tutorias go to www.arduino.cc

Creation of matrix in matlab

As the name suggests MATLAB (Matrix Laboratory) , matrix is the vital part of MATLAB. so today i am going to tell you how to create different types of matrices in MATLAB.

Informally, the terms matrix and the array are often  used interchangeably. More precisely , a matrix is a two- dimensional rectangular  array of real or complex numbers that represents a linear transformation. The linear algebraic operations defined on matrices have found applications in a wide variety of technical fields.

MATLAB has dozens of functions that create different kinds of matrices. These commands you can try on your command window of MATLAB.

1. A=magic(3)                   % creates random 3 by 3 matrix
2. B=pascal(3)                  % creates symmetric matrix
3. C=fix(10*rand(3,2))      % creates 3 by 2 rectangular matrix of random integers
4. x=[7;8;9]                      % produce a column vector
5. y=[4 5 -6]                     % produce a row vector
6. z=2                               % produce a scalar

so from this code you can try and make your own matrix in MATLAB.
