Snap4Arduino adds several new blocks to Snap! for the purpose of controlling Arduinos. Its many features are documented here, among which is worthy to mention that it is blocks-based and dynamic; supports almost all arduino boards; allows the user to interact with multiple boards simultaneously.
*Note that the web version runs only in Chrome and requires the installation of a Chrome extension. To do so unzip this file, go to chrome://extensions and drag and drop the folder there. This has already been performed if you are using an eCraft2Learn SD card on a Raspberry Pi.
*Snap4Arduino communicates with the Arduino using something called Firmata which needs to installed on the Arduino. Here are Firmata installation instructions.
*The eCraft2Learn Snap! blocks for communicating with AI cloud services and machine learning require HTTPS support. Until the site supports HTTPS we are using a fully-functional copy of Snap4Arduino except that it cannot communicate with the Snap! cloud. Projects should be saved to the browser's memory or exported to the local file system.
