SAOGNR - An SAO for Morse Code

The SAOGNR is a specialized Shitty Add-On (SAO) circuit built around a custom PCB designed to facilitate Morse code communication and interaction. At the core of the system, microcontroller and logic components execute programmed sequences to drive both visual and auditory outputs. When triggered, the logic circuitry generates timed electrical pulses that correspond to Morse code patterns. These signals simultaneously route to a built-in speaker, which translates the timed current pulses into audible audio tones, and to onboard LEDs, which flash synchronously to provide a visual indicator of the transmitted dots and dashes. Additionally, the inclusion of I2C capability allows the SAOGNR to interface with compatible host badges or external microcontrollers, enabling data exchange and expanded communication features beyond standalone operation. Power management components on the board ensure stable voltage distribution to the logic ICs, speaker driver, and LEDs, allowing the system to reliably playback canned messages or respond to interactive commands. Through the integration of discrete electronic components, a custom PCB, and standard communication protocols, the circuit transforms basic electrical switching into a functional, interactive Morse code transceiver and display system.
