about

the morse attacks board is a morse code generator & decoder for audio data transmission in morse code. The ATtiny85 microcontroller messures up to 3 sensors (light, temperature, presence, air quality ...) and broadcasts its finds by morse code. It listens also for morse code in the air and could controll up to 3 actuators (lights, motors, sound devices ...)
