Hi,
A couple of months ago I made a drawing machine using processing to control my arduino that is hooked up to two continuous rotation servos. I'm trying to use it again but I can't get the processing code to control the arduino. Please help!
Processing Code
import processing.serial.*;
Serial port;
/*Drawing Servo Controller*/
//90 is stopping
// 0 means stop
// 1 means rotate left
// 2 means rotate right
//first value for left servo
//second value for right servo
//00
//10
boolean topRecorded = false;
boolean bottomRecorded = false;
int currentAngleLeft = 0;
int currentAngleRight = 0;
int maxAngleLeft;
int maxAngleRight;
void setup () {
size(300, 400);
println("Available serial ports:");
println(Serial.list());
// Uses the first port in this list (number 0). Change this to
// select the port corresponding to your Arduino board. The last
// parameter (e.g. 9600) is the speed of the communication. It
// has to correspond to the value passed to Serial.begin() in your
// Arduino sketch.
port = new Serial(this, Serial.list()[0], 9600);
}
void draw () {
//drawing left servo draw left and right controls
background(125);
//draw record burrons
pushMatrix();
translate(width/2, 50);
//red button
fill(255, 0, 0);
text("down", 0, 0);
rect(0, 0, 30, 30);
fill(0, 255, 0);
text("up", 40, 0);
rect(0+30, 0, 30, 30);
fill(0, 0, 255);
text("stop", 60, 0);
rect(0+60, 0, 30, 30);
popMatrix();
//draw left servo visual
pushMatrix();
ellipseMode(CENTER);
translate(80, height/2-50);
rotate(radians(currentAngleLeft));
fill(255, 0, 0);
arc(0, 0, 30, 30, 0, PI+HALF_PI, PIE);
popMatrix();
//draw right servo visual
pushMatrix();
ellipseMode(CENTER);
translate(200, height/2-50);
rotate(radians(currentAngleRight));
fill(255, 0, 0);
arc(0, 0, 30, 30, 0, PI+HALF_PI, PIE);
popMatrix();
}
void mousePressed () {
if (mouseX>width/2 && mouseX<width/2+30 && mouseY>50 && mouseY<80) {
println("up");
port.write(65);
/*topRecorded=true;
currentAngleLeft = 0;
currentAngleRight = 0;*/
}
if (mouseX>width/2+30 && mouseX<width/2+60 && mouseY>50 && mouseY<80) {
println("down");
port.write(66);
/*if (topRecorded) {
bottomRecorded = true;
maxAngleLeft = currentAngleLeft;
maxAngleRight = currentAngleRight;
println("Max Angle Left: " + maxAngleLeft + ", Max Angle Right: " + maxAngleRight);
}*/
}
if (mouseX>width/2+60 && mouseX<width/2+90 && mouseY>50 && mouseY<80) {
println("stop");
port.write(67);
/*if (topRecorded) {
bottomRecorded = true;
maxAngleLeft = currentAngleLeft;
maxAngleRight = currentAngleRight;
println("Max Angle Left: " + maxAngleLeft + ", Max Angle Right: " + maxAngleRight);
}*/
}
}
