beginning serial robot control help

here is my processing code i patched together:

import processing.serial.*;
Serial myport;
int val;

void Setup()
{
  size(200,200);
  String portName = Serial.list()[4];
  myport = new Serial(this, portName, 9600);
}

void draw() {
  background(255,255,0,255);
}

void keyPressed() {
  if (key == CODED){
    if (key == UP) {
      myport.write('F');
    }
    else if (key == DOWN){
      myport.write('B');
    }
    else if (key == LEFT){
      myport.write('L');
    }
    else if (key == RIGHT){
      myport.write('R');
    }
    else{
      myport.write('S');
    }
  }
}

and arduino:

#include <Servo.h>
Servo Left;
Servo Right;
//int Lspeed = 0;
//int Rspeed = 0;  
 int val;
 
 void setup() {
 Left.attach(12);
 Right.attach(13);
 Serial.begin(9600);
 }
 
 void loop() {
 if (Serial.available()) { 
 val = Serial.read();
 }
 if (val == 'F') { // If Forward command was received
 Left.write(180); // go forward
 Right.write(0);  //invert direction for opposite motors
 } 
 else if (val == 'B') {
   Left.write(0);
   Right.write(180); 
 }
  else if (val == 'R') {
   Left.write(0);
   Right.write(0); 
 } 
 else if (val == 'L') {
   Left.write(180);
   Right.write(0); 
 }
  else  {
   Left.write(90);
   Right.write(90); 
 }
 delay(100); // Wait 100 milliseconds for next reading
 }

should this work? unfortunately I don't have any 360 degree servos to test this with at the moment... :roll_eyes:
Anyone can feel free to test this- just connect your servos to pins 12 and 13.
