The sound of 48 relays clicking controlled by Arduino using MCP23017 I/O expanders. These relays run satisfying patterns like zig-zag chase, triple pulse columns, relay rain, and domino collapse. The mechanical clicking sound makes it oddly satisfying to watch and listen to. #arduino #electronics #relays #satisfying #engineering
