Playing with Max 6 Framework

by Julien Bayle | September 2013 | Open Source

This article by Julien Bayle, the author of C programming for Arduino, teaches some tips and techniques we can use with the Max 6 graphical programming framework. We will completely describe the use of the Serial object and how to parse and select data coming from Arduino to the computer. We will design a small sound-level meter using both real LEDs and Max 6 and finish by designing a Pitch shift sound effect controlled by our own hand and a distance sensor.

In this article, we will learn how to send data to Arduino from Max 6. We will also describe how we can handle and parse the data being received from Arduino. Arduino adds a lot of features to your Max 6 programs. Indeed, it provides a way to plug Max 6 into the real physical world. Through two examples, we are going to understand a nice way of working with Arduino, the computer and most advanced programming framework ever.

Plotting data using Matplotlib: Part 1

by Sandro Tosi | October 2009 | Open Source

In this two-part article, by Sandro Tosi you will see several examples of Matplotlib usage in real-world situations, showing some of the common cases where we can use Matplotlib to draw a plot of some values.

There is a common workflow for this kind of job:

  1. Identify the best data source for the information we want to plot
  2. Extract the data of interest and elaborate it for plotting
  3. Plot the data

Usually, the hardest part is to extract and prepare the data for plotting. Due to this, we are going to show several examples of the first two steps.

Podcasting and Images in Drupal

by Bill Fitzgerald | December 2008 | Drupal Open Source

In this article by Bill Fitzgerald we will learn about Podcasting. Podcasting allows you to share audio files over the Internet. In recent years, as podcasting has increased in prominence and popularity, there has been an almost overwhelming amount of information about how to get started with podcasting: the technical requirements, the hardware, the software, and so on.

Sharing images creates a variety of ways for students to get involved in the class. In some classes, such as Photography or other Fine Arts courses, images provide a way for students to showcase their work. In other courses, online image sharing can be used to enhance the curriculum.

In this article, we will focus on cutting through the noise, and setting up your site to work as a podcasting and image sharing platform. This article will break down the technical aspects of publishing audio and images, along with ways of integrating podcasting into your class.
