This is not exactly about Snap! but there's a workshop on MicroBlocks, a live programming environment for physical computing, this Thursday:
You want to extend your teaching or workshop offerings with transferring code from the virtual into the physical world? In our next SAP Young Thinkers Trainer´s Thursday Session “Making Sense of Sensors“ on September 16th 4 – 6 pm CEST our experts John Maloney and Kathy Giori will show you how to explore the sensors built into different microcontrollers, e.g. the micro:bit, Calliope mini, or Circuit Playground Express by using the live and visual programming language MicroBlocks. Join the session in September to learn how to graph and record sensor data, and how to use sensors to create playful, interactive art and music projects with MicroBlocks. You can join the session without a microcontroller, but to enjoy the full experience you will need a supported microcontroller.

WAT ‽
You don't support the Arduino UNO?
Oh come on, if you can support the Arduino DUE you can support the Arduino UNO.
Welp, All I have is an Arduino UNO so I can't use this.
mm- well we could have a long discussion on the phrase what does "install stuff" mean
You have to have something running on the Arduino to understand how to deal with message from a block programming language and Firmata is considered the minimalist solution and has been around since the early days of Arduino
I run minimal MQTT clients on Arduino type hardware but conceptually it's just the same as running Firmata
