🐍 Snake Game on OLED with Joystick

Description:

Bring back the nostalgic arcade vibes with this minimalist Snake Game built using an Arduino, a joystick, and a 0.96" OLED screen.
Control the snake, eat the food, and grow longer — all in just 64 pixels!

---

🎮 Components:

• Arduino UNO
• 0.96" OLED Display (SSD1306, I2C)
• Joystick Module (Analog)
• Jumper Wires & Breadboard
• Optional: 10kΩ resistors (if needed for joystick voltage divider)

---

🔍 Features:

• Real-time snake movement using analog joystick input
• Auto food spawning (never on snake body!)
• Self and wall collision detection
• Game over animation and auto-reset
• Adjustable speed via moveDelay
• Compact and optimized for 128x64 OLED

---

🧠 Concepts Covered:

• OLED graphics with Adafruit GFX library
• Analog joystick input handling
• Arrays and game logic on microcontrollers
• Collision detection
• Procedural food spawning

---

📺 Demo

👉 Watch on YouTube Shorts
👉 Find Code on GitHub

---

✅ Quick Tips:

• If the joystick feels reversed, just swap X/Y pins or logic in readJoystick()
• To increase difficulty, reduce moveDelay
• Expand the project by adding a score counter, splash screen, or level system!

🧱 Brick Breaker on OLED

Part of the Hobitronics Arcade Collection

---

🎮 Game Description

A full-featured Brick Breaker game built using an Arduino UNO, joystick, and 128x64 OLED.
Use the joystick to control the paddle, bounce the ball, break all the bricks, and advance through 3 exciting levels. Game Over and Victory screens included!

---

⚙️ Components Required

• Arduino UNO
• 0.96" OLED Display (SSD1306, I2C)
• Analog Joystick Module (connected to A0)
• Jumper Wires & Breadboard

---

🧠 Key Features & Concepts

• Joystick-based paddle control (analog input)
• OLED rendering with Adafruit GFX + SSD1306
• Ball physics with basic collision detection
• Brick grid with collision response
• Game states: win, lose, reset
• Level progression with increasing difficulty
• Memory-efficient display updates using clearDisplay() and fillRect() logic

---

🕹️ Gameplay Mechanics

• Paddle: Controlled via joystick (X-axis)
• Ball: Bounces off walls, paddle, and bricks
• Bricks: Destroy on impact, earn points
• Levels:
  • Level 1 → 2 rows of bricks, slower ball
  • Level 2 → 3 rows of bricks, medium speed
  • Level 3 → 4 rows, faster ball
• Win: Clear all bricks in Level 3
• Lose: Ball falls below paddle
