So far we have numbers coming from the Arduino circuit board to the Arduino software, reading the position of Z. However, we want the numbers to appear in Processing and are having difficulties doing so. We also want to know how to use this information to animate some jumping characters. 

It is good to know that we have taken a lot of resources from a project called NAMA by  Luiz Zanotello found on this address: http://www.viraseres.com/nama/

The working code on the Arduino look like this:

And the code we have so far in Processing looks like this: 

2. import processing.serial.*;
3. 
   
4. Serial myPort;  // The serial port
5. 
   
6. void setup() {
7.   // List all the available serial ports
8.   println(Serial.list());
9.   // Open the port you are using at the rate you want:
10.   myPort = new Serial(this, Serial.list()[4], 4800);
11. }
12. 
    
13. void draw() {
14.   while (myPort.available() > 0) {
15.     int inByte = myPort.read();
16.     println(inByte);
17.   }
18. }

It would be very helpfull if you could produce a string of code (maybe for both Arduino and Processing) we can use to get the numbers from the 5 accelerometers to Processing so I can use the values to move 5 different objects up and down according to the physical movement.
