I need some help with a school project.
My Servo needs to turn by the push of a button from 0-180 degrees.
wait 1 sec.
and turn back (180-0).
another push wil repeat the actions.
i've tried to combine the examples on the arduino software but it won't work out.
can someone code send me a working coding?

We don't actually have working code for projects like that. Do you have the code you tried? If so, please post it(to post: type [code], then paste your code, the type [/code] and you will get help making it work.
Also give a bit of information, like what level of school are you in, and does your teacher mind if you get help from the internet? Personally, I think all such help should be encouraged, because using technology is a colaborative endevor.
Show what your sketch contains so far:
You can try to do a code with a variable (x, for instance). First set the variable to 1. Then, do an if statement like:
if (x == 1){
x = 0
servo.write(180)
}
if (x ==0){
x=1
servo.write(-180)
With this code when x is 1, the servo moves forward and if x is 0 the servo moves backward (I think that if you put .write(-180), the servo moves backward)
Im an industrial design student.
Currently 2nd year.
I have a Arduino from my previous study wich a didn't finish 2 years ago
In this project we need to make a dispenser system.
I don't get class in programming.
The purpose of this project is understanding how the flow a systeem works, not how to code or how you make the system work.
I found a coding online for my servo. But it makers it turn 0-180 and back continiously. So i have to add an button in the setup and loop.
Here's the code for the servo i'm trying to work with:

#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
}
}
credits to the maker of this code btw ^^
Have you tried what I said?
Not yet.
But i guess the rotation will stop moving forward and start turnimg back when you release the button.
The system needs to finish the full rotation, wait and turn back after just a single push on the button.
Anyways, thanks for your reply and the help.
OP,
The code you found has good comments everywhere. Reading the comments you should know that the second half rotates the arm back. If you insert a big delay between first and second parts, you get the effect you need. Button is a separate question.
If you don't need the servo to run slowly, just tell it where to go:
void loop()
{
if (digitalRead(ButtonPin) == LOW)
{
// The button was pressed
myservo.write(180); // tell servo to go to position 180
delay(1000); // wait one second
myservo.write(0); // tell servo to go to position 0
}
}
Motion might be too jerky.
