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
Each farm is contained within its own unique folder, typically named as FarmName_123456789 . Inside this folder, you will find four primary files: The Save File
: This is the primary save file. It contains the current state of your world, including your farm layout, chest inventories, NPC friendship levels, and world events.
This is usually due to a mod dependency missing for v1.6. Update SMAPI (Stardew Modding API) to the latest 3.18.x or higher. Launch the game via StardewModdingAPI.exe and read the terminal text—it will tell you exactly which mod is failing. save data stardew valley pc updated
Happy farming, and may your parsnips never wither.
Because Stardew Valley saves are written in plain XML text, you can edit them using any basic text editor like Notepad, Notepad++, or VS Code. This allows you to alter your character's name, change your farm type layout mid-game, change your favorite thing, or adjust your bank account. Step-by-Step Save Editing Each farm is contained within its own unique
Paste the copied folder directly into the directory. Launch the game, and your farm will appear on the load screen. How to Restore an Older Save (Undoing a Day)
Rename SaveGameInfo_old by deleting the _old suffix so it reads exactly: SaveGameInfo . This is usually due to a mod dependency missing for v1
Relaunch the game. You will start at the beginning of the previous in-game day. 6. Managing Save Files with SMAPI and Mods
Moving your farm progress to a brand new computer requires a quick manual transfer.
In an era of autopilot cloud saves and “quick resume” features, the humble act of saving a game often goes unnoticed. Yet, in Stardew Valley , ConcernedApe’s farming and life simulation masterpiece, the save system is not just a technical necessity—it is a deliberate design choice that shapes the entire rhythm of the player’s life in Pelican Town. For PC players, understanding how saving works in the latest, fully updated version of the game (including the 1.6 update and beyond) is essential, not only to prevent catastrophe but to truly appreciate the game’s unique philosophy: that rest is the only way to cement progress.
