You guys rule!
A have connected a 4 cell NiMH receiver pack to the servo and it's working fine now.
Thanks,
Edit:
This is the code I used to control 2 servos.
// Controlling servo positions using potentiometers

#include <Servo.h>
Servo myservo1; // create servo object to control servo1
Servo myservo2; // create servo object to control servo2
int potpin1 = 0; // analog pin used to connect the potentiometer
int val1; // variable to read the value from the analog pin
int potpin2 = 1; // analog pin used to connect the potentiometer
int val2; // variable to read the value from the analog pin
void setup()
{
myservo1.attach(9); // attaches servo1 on pin 9 to the servo object
myservo2.attach(10); // attaches servo2 on pin 10 to the servo object
}
void loop()
{
val1 = analogRead(potpin1); // reads the value of the potentiometer (value between 0 and 1023)
val1 = map(val1, 0, 1023, 0, 179); // scale it to use it with the servo (value between 0 and 180)
myservo1.write(val1); // sets the servo position according to the scaled value
int sensorValue1 = analogRead(potpin1);
val2 = analogRead(potpin2); // reads the value of the potentiometer (value between 0 and 1023)
val2 = map(val2, 0, 1023, 0, 179); // scale it to use it with the servo (value between 0 and 180)
myservo2.write(val2); // sets the servo position according to the scaled value
int sensorValue2 = analogRead(potpin2);
delay(15); // waits for the servo to get there
}
Why are these statements "int sensorValue2 = analogRead(potpin2);" in the sketch? I don't understand what they are doing.
