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 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
