A-SGA03 - Smart Gate and Arm Control using Joystick and Servo

Project Description:
This Arduino-based project allows the user to control a gate mechanism using a joystick, with live feedback displayed on an LCD screen. A servo motor is used to simulate the gate's movement, which opens or closes based on the joystick's vertical (Y-axis) input. When the joystick is pushed upward, the gate opens; when pulled downward, the gate closes — both in a smooth, incremental manner.
The 16x2 LCD provides real-time status updates, showing whether the gate is “Opening,” “Closing,” “Open,” or “Closed.” The Serial Monitor is also used to display the analog readings from the joystick for testing or calibration.

Components Used:

Component	Quantity	Description
Arduino UNO (or Nano)	1	Microcontroller board
Joystick Module	1	Analog joystick with X and Y axes
Servo Motor (e.g., SG90)	1	For simulating gate movement
16x2 LCD Display	1	To show gate status
Power Supply or USB	1	To power the Arduino board

Key Functionalities:
Analog Joystick Control: Reads Y-axis input to determine direction of gate movement.
Servo Movement: Smoothly rotates between 0° (closed) and 90° (open).
LCD Feedback: Displays current gate status to the user.
Serial Output: Logs joystick analog values for debugging.
