How to Use ServoTimer2 Library (Simple Explain) Servo Sweep

1#include<Servo.h>
2Servo servo1;
3void setup() 
4{
5servo1.attach(6);    // put your setup code here, to run once
6}
7void loop() 
8{  // put your   main code here, to run repeatedly:
9servo1.write(0);
10delay(1000);
11servo1.write(90);
12delay(1000);
13servo1.write(180);
14delay(1000);
15}
