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
These figures are standard reference values typically derived from the standard.
This is the most legally significant part of the document. It defines how much a real-world steel bar can deviate from the drawing.
Serves as the authoritative reference if delivered materials do not meet specifications. 4. How to Find and Use JIS G3193 PDF
: Variations depend on whether the steel has a "mill edge" (as-rolled) or a "cut edge" (trimmed), and the precision of the cutting method used.
Typical contents include:
This standard . Flat steel profiles maintain their own dedicated dimensional standard framework within the Japanese Industrial Standards catalog. Structural Correspondence with International Metrics
Sheets flattened and sheared directly out of a parent steel strip.
The core value of downloading a complete JIS G 3193 Document on Scribd lies in its exhaustive tolerance matrices. Deviations are calculated using the product's nominal thickness and width. 1. Thickness Tolerances
Understanding the content of JIS G 3193 can save a fabricator from using the wrong thickness tolerance and discovering that a 12‑mm plate is actually 11.8 mm, possibly jeopardizing a structural connection.
