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.
