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).

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
At the heart of Photopia Director is its advanced layer system. Every slide can contain an unlimited number of layers, including:
For lighting designers, electrical engineers, and visualization artists, "Photopia Director" typically refers to the advanced control and simulation tools within the Photopia optical design software family. Developed by LTI Optics, Photopia is the industry standard for designing illumination systems, LED optics, and architectural lighting.
Photopia Director: The Ultimate Guide to Professional Slideshow Creation
As we move into an era of AI-generated imagery and automated lighting rigs, the Photopia Director is becoming more valuable, not less. Why? Because AI can generate a pretty picture, but only a human Director can understand the narrative intent of a shadow. Photopia Director
At its core, Director provides a non-destructive, layer-based editing environment similar to industry standards. Users can manipulate masks, apply blending modes, and use adjustment layers to fine-tune images without altering the original source data. It supports a wide range of file formats, including RAW files from major camera manufacturers, ensuring that image quality remains pristine throughout the editing process.
"You don't take a photograph. You ask, quietly, and then you build a place where the answer can appear." — A credo for the Photopia Director.

When a fragile manuscript cannot be exposed to UV light, the Photopia Director designs a spectrum-safe LED array that provides 500 lux of illumination but zero radiant heat or harmful wavelengths. They direct photons, not just beams.
