Arduino Code:-   #include <Servo.h>  Servo esc_signal;   void setup() {      esc_signal.attach(12);        //Specify here the pin number on which the signal pin of ESC is connected.      esc_signal.write(30); //ESC arm command. ESCs won't start unless input speed is less during initialization.      delay(3000); //ESC initialization delay.      }      void loop()      {      esc_signal.write(120); //Vary this between 40-130 to change the speed of motor. Higher value, higher speed.      delay(15);      }
