Virtual Guitar String with Arduino and Max/MSP

Hello Guys,
It's been a long time since i am writing this blog. I was having a dream to generate music with hand gesture. I was looking for it. But finally i got an idea. Using Light Dependent Resistor (LDR) as a sensor, Arduino UNO as a PC interface and MAX/MSP as a Music Generator, finally i build a very basic hand movement music controller. And it sounds great....
The name behind Virtual Guitar String is that there is no string though we can change the tone of music...

Let's build it...

Max/MSP with Arduino: Multiplexing 8 inputs using 4051

Hi guys,
This post explains about interfacing Max/MSP with multiplexer 4051 using Arduino. Following is the patch code. Just copy and paste in Max window. It will automatically generate the block diagram. You will need Maxuino Patch for Arduino. And follow the comments shown in the block diagram patch.

CODE:

Arduino: LED blinking with variable speed


Hello guys,
I am feeling cool today. I am having a lot of work, but still i am making myself comfortable. So, that maybe a reason to write a blog...
Any way Guys, today we are going to make an Arduino project. This project was done in 4th semester by me and my friend, Sagar. Well, his name is also Sagar and mine too!!! 
Let’s discuss about the project aim. We are going to make a circuit which contains 3 LED. And we will write an arduino sketch to control the speed of LED Blinking. Here, we are going to make LED blinking with variable the speed. That means, LED blinking process will initially start with slow speed, then it will increase the blinking speed. And, Then again it will slow down the speed...

MATLAB: Analog QAM with Stereo Signals


Hello Guys,
I hope you are enjoying there. Today, I am having a lot of work esp. final projects for semester end. My college is off from next week due to Diwali Vacation. So, having a lot of work…
Anyway, I am taking some rest. So, wanna get back to MATLAB.
We are starting with DSB-SC scheme for modulation and demodulation. And then we will discuss Analog Qudrature Amplitude modulation scheme for sending two different signals at the same frequency band modulated with sinusoid carrier. For one signal to be modulated, we are using cosine and, for another is modulated by Sine. And we will also write a code in MATLAB to do the analysis.
Let’s look at the simple modulation scheme.

Arduino 3 Bit Counter with code and schemetics

Hi guys,
Whats going on?

I am going to show how to make 3 Bit counter using Arduino with Code and Schematics.
For making 3 bit up counter we need to first understand desired outputs.
The output for 3 bit up counter will start from 000 to 111.

000 -->> 001 -->> 010 -->> 011 -->> 100 -->> 101 -->> 110 -->> 111 -->> 000.

So for circuit, make the connection shown in the figure with arduino board. Connect digital pin 3,4 and 5 to LED via 1k register. Here make sure you connect LEDs via register. If you will not connect register, there may be possibility of high current through LED, which may result in short circuit the board.

Practical Design of “The Time Machine”


Hello Time Travelers,
     This blog is going to give an idea about travelling at Light Speed. In the climate we have designed The Time-Machine which can travel in future only.
      For understanding the possible ways to travel at the light speed (c), first we need to understand “Theory of Relativity”. It was given by famous scientist “Albert Einstein”. The Relativity had been distinguished in two parts.

C++ to Text file converter

Hi guys i have made a Batch File code by which you can convert C++ File to Text File.
I know that we can convert it by using notepad. But for understanding the purpose of Batch Coding you can try this. This code changes the file extension of C++ (.cpp) to Text (.txt). So, we can assume that your file gets converted into text file.

CODE
@echo off
Set /P userin=Enter the File name
ECHO file name is =%userin%
pause:
set str1=%userin:.cpp=%
echo.%str1%
set "str2=%str1%.txt
echo.%str2%
pause: Press any key to convert it into Text file
COPY %userin% %str2%
pause:



Save this code with .bat extension. When you run this code, use the whole path specifying the drive later also.
