vexis

vocal-to-state hardware execution bridge.

vexis is a minimalist interface designed to map wireless audio triggers to physical environmental states. it prioritizes low-latency execution and high-reliability switching.

---

logic

the system operates on a linear execution pipeline:

• capture: vocal input is processed into serialized data strings.
• transmit: data is bridged via a 2.4ghz wireless link to the processing core.
• parse: logic core identifies commands and maps them to specific output pins.
• execute: high-side switching matrix toggles physical peripheral states.

architecture

the project utilizes a modular design for isolated power management and signal integrity:

• logic core: arduino uno for string comparison and i/o management.
• wireless interface: bluetooth-to-serial bridge for remote command reception.
• switching matrix: relay-driven mechanical interface for peripheral control.
• feedback loop: led-based visual indicator for state confirmation.
