Hi, I had this kind of problem with other library which I solved by moving the files of the library into the folder of the sketch. but now nothing works heres the code(from the examples) and the error message:

#include <Servo.h>
Servo myservo; // create servo object to control a servo
int potpin = 0; // analog pin used to connect the potentiometer
int val; // variable to read the value from the analog pin
void setup() {
myservo.attach(9); // attaches the servo on pin 9 to the servo object
}
void loop() {
val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023)
val = map(val, 0, 1023, 0, 180); // scale it to use it with the servo (value between 0 and 180)
myservo.write(val); // sets the servo position according to the scaled value
delay(15); // waits for the servo to get there
}

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
it says multiple libraries were found for servo.h after saying no such file or directory. anyway I see only 1 file of the servo.h
int potpin = 0; // this points to RX pin
int potpin = A0; // this points to analog-0 pin
// BTW, use byte over int, something like this
byte potpin = A0;
// and you will save some precious 8 Bits of SRAM a piece

Hi, I had this kind of problem with other library which I solved by moving the files of the library into the folder of the sketch.
That's a patch, don't. Just place the files in the correct folder. That's the "libraries" folder in your sketchbook (NOT the libraries folder in de IDE folder). By default that's "C:\Users[user]\Documents\Arduino\libraries"
But did you mess around with the servo library files? By default they are included in the IDE for the normal boards.
And which board are you using?
@KASSIMSAMJI Although I fully agree using A0 is nicer and more universal, doing analogRead(0) will read pin A0. A digitalRead(0) (or write) will indeed read pin 0 / RX where as digitalRead(A0) will read pin A0.
I have a larger problem with the pins being an int though

I didn't mess with them they are all in the libraries folder under the folder "SERVO" inside
I suspect OneDrive as the culprit. Your current sketchbook location is in the OneDrive. Try changing your sketchbook folder location in File > Preferences > Sketchbook Location to some folder outside of OneDrive. You will need to copy the files and folders from C:\Users\danny\OneDrive\Documents\Arduino to your new location.
