ATmega 128 외부 인터럽트(INT0 ~INT3)을 이용한 LED 시프트 및 점멸 제어

Tested the circuit… and our friendship 🙊 Just to clear things up: we designed and built a custom development board using the ATmega328P microcontroller. While we referred to it as a “microcontroller” in the video for simplicity, the actual work involved schematic design, PCB layout, etching, component soldering, and testing — creating a fully functional microcontroller-based system. #techtok #engineering #computerengineering #womeninmenfields #arduino #soldering #circuit #fyp
