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
New users can often access a 14-day fully unlocked trial or even a 45-day evaluation period depending on current developer offers.
Each Giglad activation key is strictly limited to one machine at a time. Top Features of Giglad
Giglad serves as a virtual arranger that turns a PC or Mac into a professional-grade music station, comparable to high-end hardware keyboards like those from Korg or Yamaha. It is unique because it uses high-quality virtual instruments (VST/VST3/Audio Units) and audio loops rather than standard MIDI tracks, providing a more modern and expansive sound.
Giglad activation keys are unique identifiers used to license Giglad , a professional software arranger designed for live performance and music production. These keys bind to a single machine to prevent unauthorized copying, though they can be "moved" between computers by deactivating the software on the original device before activating it on the new one.
Upon launching the software for the first time, you are prompted to enter a valid license key or register for a trial to unlock critical resources like styles, presets, and the sound library.
For musicians looking to maximize their activation, Giglad offers several "top" features that bridge the gap between software and hardware arrangers: Giglad- Professional Software Arranger
