WEEK 12: INTERFACE/APPLICATION PROGRAMMING & PROJECT UPDATE

Interface and application programming

I am completely new to this topic, so taking into account the time limitations of a week before the final project, I decided to start playing with some of the tools in order to get a first grasp and know where to start after I´m done with the final project.

As soon as Neil explained the different programming alternatives, I knew Processing was gonna be “the one”. I loved the arduino learning curve for electronics, so it was the natural next step to try with Processing for interface&application programming.

I started with the beginner tutorials:

http://www.processing.org/tutorials/

And then I found something it is gonna be really useful in the future, how to easily connect processing and arduino:

Following this tutorial I was able to control the led on my custom arduino by clicking on the grey screen in the picture.

Then I started realizing about the potential of this “new world” that is being opened in front of my eyes. I thought it would be super cool to implement voice command in my final project, so I started looking for libraries that could do that.

The most promising library for processing I found so far: http://voce.sourceforge.net

I found some tutorials too:

I tried to follow the tutorials but I was getting the following error:

I guess I´m doing something wrong with setting up the library, but I really don´t have any skill to try to debug this.

I kept looking for more tools that could let me do voice command with my microcontroller. The bitvoicer library for arduino seemed promising, but it only runs in windows.

Final project update

A brief graphic summary of the subsystems of my “low cost everywhere display platform”:

The system

Carriage = 3D design + 3D printing

Pan/Tilt Bracket = 2D design + Waterjet + Bending

Hasiduino = Electronics Design + Fabrication

DC motor + Servos = Output Devices

Input devices = RFID reader

Communications = Bluetooth Terminal
