A-SLI03 - GlowStick Joystick

📝 Project Title:
“GlowStick
Joystick”

---

🔍 Project Description:
This project
is a simple yet powerful directional control system using a joystick, LEDs, and
a 16x2 LCD display. It simulates the directional control of a robotic arm or
mechanism by interpreting joystick movements and responding visually with
color-coded LEDs and text feedback on the LCD.

• When the joystick is moved UP, a
  Red LED (L1) lights up and the LCD shows "Arm Up L1: ON".

• When moved DOWN, a Green LED (L2)
  turns ON with the message "Arm Down L2: ON".

• Moving LEFT lights a Yellow LED
  (L3) and displays "Arm Left L3: ON".

• Moving RIGHT activates a Blue LED
  (L4) and displays "Arm Right L4: ON".

• When the joystick is centered, all
  LEDs are OFF, and the LCD shows "Arm Idle ALL OFF".

This system
mimics real-world robotic arm interfaces and is ideal for beginners learning
about analog sensors, digital outputs, and LCD interfacing.

🚀 Applications:

• ✅ Robotic Arm Simulators –
  Indicating basic movement directions

• ✅ STEM Learning Kits – Demonstrating
  sensor-actuator interaction

• ✅ Game Controllers – Showing
  joystick-based feedback visually

• ✅ Control Panels – Teaching LCD
  interfacing with analog inputs

• ✅ Educational Demos – Helping
  students understand analog-digital conversion
