Pan and Tilt

To aim our launcher, we need two degrees of freedom:

1. Pan: Moving left and right (Azimuth).
2. Tilt: Moving up and down (Elevation).

We use Servos for this because they can hold a specific angle preciseley.

Controlling Servos

In code, we simply tell the servo what angle to go to:

#include <Servo.h>

Servo panServo;
Servo tiltServo;

void setup() {
  panServo.attach(9);
  tiltServo.attach(10);
}

void loop() {
  panServo.write(90); // Center
  tiltServo.write(45); // 45 degrees up
}
