larry i am your big , large , fan and i being trying your projects all the time its fun .
greetings for your hard work and passion .
i just wantedd to tell that the code shows error like

Exception in thread “Animation Thread” java.lang.ArrayIndexOutOfBoundsException: 1
at sketch_jan07a.setup(sketch_jan07a.java:52)
at processing.core.PApplet.handleDraw(Unknown Source)
at processing.core.PApplet.run(Unknown Source)
at java.lang.Thread.run(Thread.java:662)
in the processing ide please help me out.

Please, can you post a valid or alternative url or post the Arduino+Ping code to do rotating solar system? Thanks

ok i am a noob at this i like your video and everything but this project i dont understand… the radar sweep in processing is just a still picture not like yours were it interacts with the arduino how do you do it like how you are showing it in the project

Looks like that there is a little bug in the processing code.

Replace the follwing. And the code for the Arduino won’t work. I make my own code. Still have only a servo, no sonar device.

void setup(){
// setup the background size, colour and font.
size(750, 450);
background (0); // 0 = black
myFont = createFont(“verdana”, 12);
textFont(myFont);
// setup the serial port and buffer
println(Serial.list());
String portName = Serial.list()[1];
myPort = new Serial(this, portName, 9600);
myPort.bufferUntil(‘\n’); \\ \n instead of n
}

…..
/* get values from serial port */
void serialEvent (Serial myPort) {
String xString = myPort.readStringUntil(‘\n’); // read the serial port until a new line
// \n instead of n
if (xString != null) { // if theres data in between the new lines
…..

Pretty cool projecy !

Hey I have more ideas continuing your work, check this out!

I use 4 sensors and the the system must able to interpret the data for 360 degrees.
So using 4 sensors, I can make the servo works faster and less burden with only rotate for 90 degrees.

the serial monitor is like the Arduino one in that if you use the Serial.println() command it will write something in the bottom half of the program normally the black window.

I can run the code fine without any errors here, so would suggest maybe its the baud rate settings for you or com ports aren’t setup. Most likely its because you’re using the serial port in another application.

But its odd that this program doesnt work yet my other works fine.

It says: error, disabling serialEvent() for //./COM16
