Snap4Arduino was a Snap! extension, a full Snap! implementation to interact with the physical world, through many types of electronic devices, especially those compatible with Arduino. Starting with Snap! v11, the S4A Connector library is doing this job.
Snap! is a broadly inviting programming language for kids and adults that's also a platform for serious study of computer science. It is inspired by Scratch, written by Jens Mönig and Brian Harvey and presented by the University of California at Berkeley.
Snap4Arduino requiere boards with Firmata firmware installed. Check devices section.
Just download, unpack/unzpip and click Snap4Arduino.
Choose your system: Windows 64 (or its portable option), GNU/Linux 64, MacOSX, Windows32 (or its portable) or GNU/Linux 32.
Install Snap4Arduino connector and then, just play Snap4Arduino online (you can install it as an app from the browser to run it offline).
Chromium/Chrome/Edge browsers are required
Download Snap4Arduino connector, unzip its crx folder, type chrome://extensions, select Developer mode and Upload an unpacked extension selecting that crx file (or just drag and drop it).
Just play Snap4Arduino online (you can install it as an app from the browser to run it offline).
Play online
Plugin for Chromebooks (chrome web store)
Chrome/Chromium/Edge plugin (download extension)
Last Snap4Arduino version is 10.3.6 (released on 08/01/2025) and its Snap4Arduino connector version (chrome extension)is 8.0
You can also find older releases and unmaintained versions
Snap4Arduino requires boards with Firmata firmware uploaded.
You can upload Firmata firmwares direcly from Snap4Arduino (with both desktop and online versions) to UNOs compatible boards. Or just here:
A lot of devices support Standard Firmata. Tested on Nano, Mega, Leonardo and Micro.
Many 32 bit devices support Firmata. Tested on Due, 101, ESP8266 and NodeMCU.
Standard Firmata is directly uploadable with any Arduino IDE.
Other options are: SA5Firmata, Creative Robotix Firmata, MC Firmata Collection, Robotics-unleashed, Snap4ArduinoDev, LCD Firmata and Ultrasound Firmata
In the pantheon of gaming history, few names carry the same weight of untouchable prestige as Neo Geo. For the arcade junkies of the early 1990s, the sight of that sleek gold and black cartridge slot was a promise: "You are about to play the best-looking, best-sounding, and hardest game you have ever seen." The original Neo Geo AES (Advanced Entertainment System) was the "Ferrari of consoles"—a machine so expensive ($650 in 1991, with $200 cartridges) that it existed only in the dreams of suburban kids who rented it for birthday parties.
The Neo Geo X was a bold attempt to revive the iconic Neo Geo brand in a portable format. While the console faced challenges and controversies, it demonstrated a demand for retro-style gaming experiences and paved the way for future retro consoles. The Neo Geo X's legacy can be seen in the range of retro consoles that followed, and it remains a beloved console among retro gaming enthusiasts.
: A full-sized USB replica of the original AES arcade controller. Key Features & Games The system comes pre-loaded with 20 classic SNK titles , including staples of the 90s arcade scene:
The NeoGeo X serves as a bridge between the analog past and the digital present. It wasn't perfect, but it allowed a new generation of players to feel the "click" of an SNK joystick and experience the sheer vibrance of Metal Slug without spending thousands of dollars on original AES cartridges. For the hardcore SNK fan, it remains a stylish, if flawed, love letter to the 16-bit era.
Based on the analysis of the Neo Geo X, several recommendations can be made:
