An engineer documents a Raspberry Pi–based controller originally developed in 2017 and deployed in 2021 to operate double‑swing driveway gates using an Explorer Hat and SainSmart 4‑channel opto‑isolated 5V relays. An AI assistant dubbed 'Ava' reverse‑engineered a Finite State Machine and refactored code, while EMI damaged inputs during initial deployment, prompting opto‑isolation and input‑protection upgrades.
