Arduino Marble Labyrinth

Create a tilting maze platform.

1. Cut a large cardboard square as the base of your maze.
2. Draw or glue cardboard strips to create maze walls.
3. Leave a starting point and an ending goal.
4. Attach the base to two servo motor arms so it can tilt in X and Y directions.

Connect servos for X and Y tilt control.

1. Connect the first servo (X-axis) to digital pin 9.
2. Connect the second servo (Y-axis) to digital pin 10.
3. Connect both servo power wires to 5V and ground wires to GND.

Wire the joystick to control the maze tilt.

1. Connect the joystick VCC to 5V and GND to GND.
2. Connect the joystick X-axis output to analog pin A0.
3. Connect the joystick Y-axis output to analog pin A1.

Map joystick input to servo positions.

1. Open Arduino IDE and create a new sketch.
2. Copy the complete labyrinth control sketch below.
3. The sketch reads joystick values and maps them to servo angles.
4. Upload to your Arduino.

#include <Servo.h>

Servo servoX;
Servo servoY;

const int joystickXPin = A0;
const int joystickYPin = A1;

int centerX = 512;
int centerY = 512;
int deadZone = 50;

void setup() {
  servoX.attach(9);
  servoY.attach(10);
  
  servoX.write(90);
  servoY.write(90);
  
  Serial.begin(9600);
}

void loop() {
  int joyX = analogRead(joystickXPin);
  int joyY = analogRead(joystickYPin);
  
  int servoXAngle = 90;
  int servoYAngle = 90;
  
  if (abs(joyX - centerX) > deadZone) {
    servoXAngle = map(joyX, 0, 1023, 60, 120);
  }
  
  if (abs(joyY - centerY) > deadZone) {
    servoYAngle = map(joyY, 0, 1023, 60, 120);
  }
  
  servoX.write(servoXAngle);
  servoY.write(servoYAngle);
  
  delay(15);
}

Test the game and adjust sensitivity.

1. Place a marble at the starting point.
2. Use the joystick to tilt the maze and guide the marble to the goal.
3. Adjust the map() ranges in your sketch to fine-tune the tilt responsiveness.
