Nontendo is a minimal gamepad project built using the Glyph-C3 board from PCBCupid. It showcases a set of classic retro-style games implemented directly on the ESP32-C3 microcontroller, featuring simple display, audio, and button inputs — all built into the tiny Glyph-C3 form factor.
This repository includes fully working Arduino-based implementations of the following games:
| Game | Folder Name | Description |
|---|---|---|
| 🐍 Snake | work |
A thinner, slower snake game with buzzer and win/lose states. |
| 🧍 Prince of Persia | peasant-of-persia |
A tiny tribute with basic movement, traps, and ledges. |
| ❌⭕ Tic Tac Toe | tic-tac-toe |
2-player local mode with visual feedback. |
| 🏓 Pong | pong |
Single or dual-player paddle battle. |
- Board: Glyph-C3 (ESP32-C3 based)
- Display: 128×32 I2C OLED (SSD1306)
- Inputs: Two tactile buttons (
leftBtn = GPIO3,rightBtn = GPIO2) - Audio: Buzzer on GPIO21 for sound effects
Each game is a self-contained Arduino sketch that you can compile and flash using the Arduino IDE or PlatformIO.
- Arduino IDE (or PlatformIO)
- ESP32 board package (ensure ESP32-C3 is selected)
- Libraries:
| Pin | Connected To |
|---|---|
| GPIO2 | Right Button |
| GPIO3 | Left Button |
| GPIO21 | Buzzer |
| I2C (OLED) | SDA, SCL lines |
- Open the Arduino IDE
- Load a sketch (e.g.,
workfor Snake) - Select the board:
ESP32C3 Dev Module - Select the correct COM port
- Upload the code
- All games use left and right buttons for interaction.
- Some games rely on rotation or screen orientation.
- Sounds play via a passive buzzer on game events (e.g., collision, win, etc.).
- All graphics are optimized for a 128×32 OLED screen.
- Hardware: Glyph-C3 by PCBCupid
