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
Before attempting this process, you must evaluate the strict legal frameworks surrounding hardware identifiers.
If the displayed IMEI matches the one you entered, the process was successful. If the IMEI shows as "0" or "Unknown," your EFS partition may be corrupted, and you should restore your backup immediately.
While technically possible on some devices, changing IMEI with Magisk is:
Open LSPosed, navigate to , select the installed IMEI changer, and Enable it. change imei with magisk
Reboot your phone completely to let Magisk apply the boot-time overlay. Open your stock phone dialer app. Type *#06# .

If the IMEI entered is invalid or incorrectly formatted, your phone will fail to register with the network (no service). Before attempting this process, you must evaluate the
Changing hardware IDs can sometimes trigger security flags. Use modules like Play Integrity Fix alongside your changes to maintain app compatibility. Module Conflicts: Only use one IMEI changer at a time to avoid boot loops. Always perform a Nandroid backup or a backup of your EFS partition via TWRP before attempting hardware ID modifications. backup the EFS partition specifically for Samsung or Pixel devices?
No. The IMEI is hardcoded into your device's hardware. Changing your SIM only changes your subscriber information, and a factory reset only erases user data, not the device's core firmware.
Reboot your device. Your original, hardware-coded IMEI will return. Conclusion While technically possible on some devices, changing IMEI
Navigate to Settings > About Phone > Status Information > IMEI Information to verify consistency across the OS.
The network partition has become corrupted. Immediately boot into your custom recovery and restore the EFS/NVRAM backup you created in Step 1.
