+Variables and Data Types - Drone Example
+==========================================
+This example demonstrates different data types using a drone scenario
+from RobotX Workshops.
+"""
+
+# Integer: Used for whole number values
+# altitude_meters represents the drone's altitude in meters
+# We use an integer because altitude is typically measured in whole meters
+# Example: 15 meters, 50 meters, 100 meters
+altitude_meters = 50
+print(f"Drone altitude: {altitude_meters} meters")
+
+# Float: Used for decimal/precise numerical values
+# battery_voltage represents the drone's battery voltage
+# We use a float because voltage requires precision with decimal points
+# Example: 12.6V, 11.4V, 10.8V
+battery_voltage = 12.6
+print(f"Battery voltage: {battery_voltage}V")
+
+# String: Used for text data
+# drone_model represents the name/model of the drone
+# We use a string because model names contain text characters
+# Example: "DJI Mavic", "Parrot Anafi", "Custom Quadcopter"
+drone_model = "DJI Mavic Air 2"
+print(f"Drone model: {drone_model}")
+
+# Boolean: Used for true/false states
+# is_armed indicates whether the drone motors are armed and ready for flight
+# We use a boolean because the drone can only be armed (True) or disarmed (False)
+# This is critical for safety - motors won't spin when False
+is_armed = False
+print(f"Drone armed status: {is_armed}")
+
+# Display all variables together
+print("\n--- Drone Status Summary ---")
+print(f"Model: {drone_model}")
+print(f"Altitude: {altitude_meters} meters")
+print(f"Battery: {battery_voltage}V")
+print(f"Armed: {is_armed}")
