Learning embedded programming demands coding knowledge as well as basic electronics skills. To explore if a different programming paradigm can help with learning, we developed Flowboard, which uses Flow-Based Programming (FBP) rather than the usual imperative programming paradigm. This way, users code using processing nodes arranged in a graph instead of command sequences. Flowboard consists of a visual flow-based editor on an iPad, an Arduino board in the hardware frame and two breadboards next to the iPad, letting learners connect their visual graphs seamlessly to the electronics. Graph edits are implemented directly, making Flowboard a live coding environment.enEmbedded Development EnvironmentsYoung LearnersLearning ToolsText/Conference Paper10.18420/delfi2023-501617-5468
