Arduino for Beginners - 2022 Complete Course - Blink Multiple LEDs without delay ()

The video tutorial explains how to make two LEDs blink at different rates without using delays in the loop function. It covers setting up the LEDs, defining variables, and implementing a structure to toggle LED states based on time intervals. The tutorial also discusses when it is appropriate to use delays in code, such as during initialization or when waiting for sensor responses. The approach allows for more flexible and efficient programming, especially when handling multiple actions simultaneously.

What is the importance of storing the LED states outside of the loop function?

What is the role of the 'digitalWrite' function in controlling the LEDs?

How can the structure used for blinking LEDs be applied to other actions?

In what scenarios is it acceptable to use 'delay' in the code?
