Some body help me please..
I am a nubi in arduino..
I need to use an arduino uno board to control 2 motor servo,with java application,
I had bought the arduino and the servo, is there somebody can help me with source code on arduino and java?
And how i put the two servo on arduino board? :~
Regards;
Have you looked at Processing?
Have you looked at any of the worked examples?
(I deleted your other post on this subject to save other people wasting their time)
Of course i had, but i not too understand, sorry for my useless post,
i just wanna to understand about an arduino with java and motor servo..
Simple servo test code for servo testing.
// zoomkat 10-22-11 serial servo test
// type servo position 0 to 180 in serial monitor
// or for writeMicroseconds, use a value like 1500
// for IDE 0022 and later
// Powering a servo from the arduino usually *DOES NOT WORK*.
String readString;
#include <Servo.h>
Servo myservo; // create servo object to control a servo
void setup() {
Serial.begin(9600);
myservo.writeMicroseconds(1500); //set initial servo position if desired
myservo.attach(7); //the pin for the servo control
Serial.println("servo-test-22-dual-input"); // so I can keep track of what is loaded
}
void loop() {
while (Serial.available()) {
char c = Serial.read(); //gets one byte from serial buffer
readString += c; //makes the string readString
delay(2); //slow looping to allow buffer to fill with next character
}
if (readString.length() >0) {
Serial.println(readString); //so you can see the captured string
int n = readString.toInt(); //convert readString into a number
// auto select appropriate value, copied from someone elses code.
if(n >= 500)
{
Serial.print("writing Microseconds: ");
Serial.println(n);
myservo.writeMicroseconds(n);
}
else
{
Serial.print("writing Angle: ");
Serial.println(n);
myservo.write(n);
}
readString=""; //empty for next input
}
}
hai zoomkat..
many thanks for your comment, is this sketch will recieve the serial data from java?
which part of this sketch accepting data from java??

The code will receive data from most any application (java, VB, or whatever) that outputs the appropriate rs232 based serial communication.
when i sending data to arduino from java, what kind of data type i have to send?

Ascii characters. Start testing by using the serial monitor. Java questions probably should be posted in a java forum for best answers.
