Tutorial 12: Blink an LED without using the delay() function: Arduino Course for Absolute Beginners

The video tutorial explains how to blink an LED on an Arduino without using the delay function, which can halt other processes. It covers the materials needed, circuit setup, and provides a detailed explanation of the code, focusing on using the Millis function to manage timing without delays. This approach allows for multitasking on the Arduino, enabling other processes to run while the LED blinks.
