Hello, I have looked hi and low on this forum and have not found the answer that will work (FOR ME) may be because I am new,
I am using the example servo sweep but only want it to run a full sweep 40 times than stop till ether button push or even reset ,
OK do a for loop that iterates 40 times. Then hold in a while loop until the button is pushed.
void loop(){
for(int i = 0 ; i<40; i++){
// code for doing the sweep
}
while(digitalRead(pushButton) == HIGH) { } // hold until button is pushed or Arduino is reset
}
I think that is what I am looking for however I get the error (expected primary-expression before '<' token)
This is the code I would like to run 40 times than stop
Where should I place the code you gave me?

#include <Servo.h>
Servo myservo; // create servo object to control a servo
// twelve servo objects can be created on most boards
int pos = 0; // variable to store the servo position
void setup() {
myservo.attach(9); // attaches the servo on pin 9 to the servo object
}
void loop() {
for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees
// in steps of 1 degree
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
}
for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
}
}
however I get the error (expected primary-expression before '<' token)
I don't get that error when I compile your code, so I am puzzled.

The whole of what you have in the loop function at the moment should be placed at the comment
// code for doing the sweep
EDIT - corrected the code in reply #1.
Note you replace pushButton with the number of the pin you are using for the push button as well as putting a pinMode(pushButton, INPUT_PULLUP) in the setup function.
