Picture of Tactile keyboard / game controller with Arduino and Processing
This instructable describes a quick and simple way to create a tactile keyboard or game controller using
- cardboard,
- aluminium foil,
- and an Arduino.

It also provides the Arduino and Processing codes to immediately start playing !

Ideal for quick prototyping of games and electronic setup, as well as for educational purposes

Step 1: Prepare the tactile keyboard

Picture of Prepare the tactile keyboard
Cut pieces of aluminum foil to make the keys. Simply tape them to a piece of cardboard.

Shapes, dimensions, and arrangement of the keys can be varied. In this example, I used triangle shapes arranged in a Top/Down/Left/Right configuration to create a game controller.

Round shapes in a line, can make a keyboard, for a visual or musical control panel, for example.

Thankd for the reply. I was able to set things up
http://i46.tinypic.com/e86dc2.jpg

is it possible to run another processing sketch

eg \\\\\\\\\ import processing.dxf.*;

void setup() {
size(400, 400, P3D);

background(#DEF6FF);
beginRaw(DXF,"positions.dxf");
}

void draw() {

}

void mouseDragged() {
fill(#0299CE);
ellipse(mouseX, mouseY,10, 10);
}

void keyPressed() {
endRaw();
exit();
}\\\\\\\\\\\\\\\\\

within a case statement or link the case statement to another sketch , so that when a button is pressed, the other sketch runs ?

Not sure I understand, but you might be complicating things. Can't you just put the "button" code in a function or a class?

is it possible to print t,b,l,r into a text file when pressed ?
donmatito (author)  cantona2 years ago
Yes, I am pretty sure it is possible, although I have not done it myself.

The Processing code can do that easily with the createWriter() commande. You can see an example at http://www.processing.org/reference/createWriter_.html

Other than that , you could try to do it using Gobetwino (http://playground.arduino.cc/Interfacing/GoBetwino) or using the write() function of the SD library if you log your file on a SD card (http://arduino.cc/en/Reference/SD).

Let us know how it goes !
