basic interfacing with servo motor.

THIS CODE WILL ROTATE THE SERVO MOTOR FROM 0 TO 180 AND 180 TO 0 FOR EVERY 3 SECONDS. THIS IS THE BASIC INTERFACING OF SERVO MOTOR WITH ARDUINO UNO WHICH MAY BE HELPFUL FOR BUILDING LARGER PROJECTS. #include <Servo.h> Servo servo; int angle = 0; void setup() {   servo.attach(3); } void loop() {   for(angle = 0;angle<181;angle++)   {     servo.write(angle);   }   delay(3000);   for(angle = 180;angle>0;angle--)   {     servo.write(angle);   }   delay(3000); }
