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
When a program requests MS Shell Dlg 2, Windows checks the system registry, identifies the substitute font, and loads that physical font instead. What Font is Actually Being Displayed?
This mapping is controlled by a specific Registry key, which we will look at shortly.
When Windows sees this placeholder, it looks at the system's registry to see which actual physical font should be substituted. typically maps to MS Sans Serif or Arial.
I can provide the exact step-by-step instructions or registry scripts needed to resolve your problem. Share public link
because MS Shell Dlg 2 is not a real font file. Searching for ms shell dlg 2.ttf will not yield a valid font. Instead, you need to use or download the actual font it points to: Microsoft Sans Serif .
Developers using Wine on Linux or macOS to run Windows applications often run into text rendering errors because the host system does not understand the Windows font alias.
