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
To establish a successful handshake between the utility and the phone:
Might be necessary depending on the version of Windows. Step-by-Step Instructions
from official sources. Here's why:
Launch the Motorola iDEN CNS Unlocker v7.0.exe executable file. Navigate to the or Port Configuration menu.
Motorola Iden CNS Unlocker Ver 7.0 is a specialized software tool developed to unlock Motorola phones with Iden technology, which was widely used in the past. The software allows users to remove network restrictions and use their Motorola phones with any carrier. This tool is particularly useful for individuals who have purchased phones from carriers and want to switch to a different network provider.
While older versions like v4.0 were common, newer iterations like v7.0 or v7.1 provide updated compatibility for late-era iDEN models. How to Use the Unlocker
Understanding Motorola iDEN Technology and SIM Locking Motorola iDEN (integrated Digital Enhanced Network) was a proprietary mobile telecommunications technology. It combined the capabilities of a cellular telephone, a two-way radio, a alphanumeric pager, and a data modem. Popularized globally by carriers like Nextel in the United States, Boost Mobile, and SouthernLINC, iDEN devices operated on unique frequency bands.
