Swift to Hack Hardware
summary
Swift runs on Raspberry Pi to read sensors, identify coins by weight and post deposits to a server. The build uses Swift on Raspberry Pi, a Swift package plus GPIO bindings to bit‑bang a 24‑bit two’s‑complement stream from an HX711 load cell amplifier, and drives an HD44780 LCD for status. Code converts raw weight deltas to coin values, wraps them in a Codable deposit struct, and posts them to a Swift server so mobile clients see live balances.
