GitHub - shazahradz/Arduino-AVR-Assembly-Distance-Measuring-System: A digital distance measuring device using the HC-SR04 ultrasonic sensor and MAX7219 7-segment display. The Arduino sketch calls assembly routines for SPI control, display handling, pulse-width measurement, and distance conversion. Designed to demonstrate low-level AVR assembly integration with Arduino.
