Hello'
I am new with arduino. I have arduino uno board and want run 2 continuous servo motor with one joystick (2 axis). But instead of using two axis of the joystick, I want want to use only one axis of the joystick to rotate 2 continuous servo motor which I apply to drive a car and gradually wanted to vary the speed of continuous motors.. Please help....
Hi,
So you want to use the joystick as a throttle.

I want want to use only one axis of the joystick to rotate 2 continuous servo motor which I apply to drive a car and gradually wanted to vary the speed of continuous motors.
The below might be close to what you want. I don't have servos or pots to test now, so the below may/may not work.
//zoomkat 8-21-15 pot servo test
//opposite side servos rotate together
#include <Servo.h>
Servo myservo1; // create servo object to control a servo
Servo myservo2;
int potpinS1 = 0; //analog input pin A0
int newvalS1, oldvalS1;
void setup() {
Serial.begin(9600);
myservo1.attach(8);
myservo2.attach(9);
Serial.println("servo joystick test"); // so I can keep track of what is loaded
}
void loop() {
newvalS1 = analogRead(potpinS1);
newvalS1 = map(newvalS1, 0, 1023, 70, 110); //servo operating band
//add some dead band
if (newvalS1 < (oldvalS1-1) || newvalS1 > (oldvalS1+1)){
//value sent to servos
Serial.println(newvalS1);
myservo1.write(newvalS1);
Serial.println(180-newvalS1);
myservo2.write(180-newvalS1);
Serial.println(); //seperate values in serial monitor
oldvalS1=newvalS1;
}
delay(50); //slow down looping to better read serial monitor
}
Thanks for the programming #Zoomkat. But the programming is applicable for Normal servo motor. Can not run the continuous servo motor (parallax).. Please help. I'm attaching the data sheet of continuous servo motor.

Yes TOM.. Can you help???
