Livebook Meets GRiSP
summary
Livebook runs on a cloud node and connects to GRiSP boards to run code remotely, demoing LED control and sensors on two boards (one in Costa Rica) and a cloud node — the ultrasonic sensor returns ~43 inches and ambient light readings update live. Uses Braid to provide mTLS with secure element so boards never expose private keys, and Livebook works by side-loading Elixir modules onto Erlang nodes. Limits: only one attached node per Livebook instance, no mix install so plotting failed in the demo.
