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
Many people fall into the trap of "I'll start my wellness journey once I lose 10 pounds." Body positivity teaches us that you are worthy of wellness . You don’t need to "earn" the right to eat well or wear cute workout gear. By embracing your body today, you create a sustainable foundation for healthy habits that actually last, because they are built on a foundation of respect rather than shame. The Ripple Effect
Historically, "health" was often measured by a number on a scale or a BMI chart. Body positivity challenges this by asserting that health exists across a wide spectrum of sizes. When you remove the pressure to look a certain way, wellness stops being a chore and starts being an act of self-care.
If you hate the treadmill, get off it. Body positivity encourages "joyful movement"—physical activity that you actually enjoy. Whether it’s a dance class, a hike with friends, gardening, or restorative yoga, movement should feel like a celebration of what your body can do, not a penalty for its appearance. 2. Intuitive Eating
Speaking to yourself with the same kindness you’d offer a friend.
