// C++ Arduino Code (Copy Below)

#include <Servo.h>

Servo keeper;  // Create servo object

void setup() {

  keeper.attach(9);  // Servo signal pin connected to D9

}

void loop() {

  // Move quickly to 0 degrees

  keeper.writeMicroseconds(66);   // 0° position

  delay(250);

  // Move quickly to 180 degrees

  keeper.writeMicroseconds(2500);  // 180° position

  delay(500);

  // Move back to 0 degrees

What You Need for This Project

To build this Automatic Goalkeeper, we used the following parts from the Plzpapa Basic Robotic Kit:

• Arduino Uno Board
• Servo Motor (SG90)
• Wooden Goalkeeper Structure
• Jumper Wires
• (No soldering required!)
