Arduino for Beginners - 2022 Complete Course - Activity 02- Make an LED Fade In/Out

The video tutorial guides students through a challenge to make an LED fade in and out using programming concepts. It provides hints on initializing the LED and using for loops to control the LED's brightness. The tutorial explains the use of the analog write function and the importance of adding a delay to make the fading effect visible. Students are encouraged to practice and experiment with the delay value to achieve the desired effect.

Describe the structure of the for loop you would use to decrease the index from 255 to 0.

Why is it important to add a delay between each analog write in the loop?
