INT0 pin is gated with timer 0. TMR0 starts when INT0 pin is high (start of the echo pulse from HC-SR04) and is read when INT0 pin is low (invoked by the falling edge interrupt caused by the end of echo from HC-SR04). Thus we get pulse width in microseconds. 16 such time samples are taken to make the measurements accurate.

Driving Adafruit's Neopixel (WS2812) Strip with AVR's Hardware SPI

4

When it comes to driving WS2812 smart RGB LEDs the most difficult task is to overcome the extremely low timed time-slotting protocol as the LEDs don't have SPI/I2C/UART interface. One smart way to overcome this issue is to use the MOSI of hardware SPI at high speed. Please note though Arduino Nano is used, this is not an Arduino-based project.
