ESP32 retro console 11 games GitHub

Karthick Nagarajan on May 24 posted an ESP32 handheld gaming console build that packages a small OLED screen, four buttons and a buzzer into a DIY arcade project, according to the social post cited in the briefing. The code and hardware notes are published in Nagarajan’s GitHub repository for his “Learn Tech With Karthick” channel. GitHub describes the console as firmware for an ESP32 DevKit V1 running on a 128×64 SSD1306 OLED display. ### How many games does the project actually include? The GitHub repository says the current ESP32 build runs “ten arcade-style games” on the OLED display. The project folder includes source files for Asteroids, Breakout, Dino, Flappy Bird, Maze Runner, Pacman, Pong, Snake, Space Invaders, Tank and Tetris, but the repository summary says Tank is present in the folder and “is not wired into the menu in the current sketch.” (github.com) The named games line up with most of the titles described in the social briefing, but the repository’s own README is more specific about what is playable now. That makes the current public build a ten-game menu, with an eleventh game file included in the codebase but not yet exposed in the main launcher. ### What hardware does the build use? (github.com) The README lists an ESP32 DevKit V1 with an ESP32-WROOM-32 module, a 128×64 I2C SSD1306 OLED, four momentary tactile switches and a passive piezo buzzer. The repository says the board is USB-powered for development, and adds that a 3.7-volt LiPo battery and charger module can be added for battery use. (github.com) The same README says the display is a 3.3-volt part and the buzzer is driven from a GPIO pin through a series resistor. GitHub also says the project can be assembled on a breadboard, perfboard or a custom add-on board, depending on how permanent the builder wants the console to be. ### What does Nagarajan publish for people who want to copy it? (github.com) The repository says it includes source code, wiring notes, project assets and a folder-specific README with hardware, libraries and upload steps. GitHub lists the project under an MIT license unless a subfolder says otherwise, which allows reuse with relatively few restrictions. The Arduino setup instructions in the console README tell builders to install the Espressif ESP32 board package in Arduino IDE and select “ESP32 Dev Module” under the ESP32 Arduino board menu. (github.com) The project also says it uses the U8g2 graphics library on the SSD1306 display. ### Is this an emulator or a set of custom mini-games? GitHub describes the project as “portable game console firmware ported from the Arduino UNO R4 version,” not as a ROM-based emulator. (github.com) The included files are individual game headers and a single `esp32_gaming_console.ino` sketch, which indicates the games are compiled as part of one microcontroller project rather than loaded as separate commercial game images. (github.com) The repository’s top-level README also frames the build as an ESP32 handheld gaming console project for viewers of Nagarajan’s YouTube channel. That places it closer to an open-source embedded-systems demo than to a packaged consumer handheld. ### Where can builders find the next step? The GitHub repository says builders should open the `esp32_gaming_console` folder, read that folder’s README and follow the listed hardware, library and upload steps. (github.com) The project page also points users to Nagarajan’s YouTube channel, “Learn Tech With Karthick,” for the companion build material tied to the code release. (github.com)
