How marwarashwan/ev-smart-car- works
This repository is a documented Smart EV control-and-sensing schematic, not an executable software project. Its principal flow is power regulation and sensor acquisition, followed by compute/control communication and relay-based motor cut-off. The README documents the component roles and wiring; no source code is available to verify behavior beyond those descriptions.
