Arduino for Beginners - 2022 Complete Course - Activity 09 - Rewrite the Previous Activity on Serial without delay ()

The video tutorial revisits activity #8, focusing on improving the LED blink code. Initially, the code uses a fixed delay, which blocks the program and prevents real-time changes. The tutorial identifies this issue and proposes a solution that allows immediate delay changes via serial communication, enabling other actions to be performed concurrently. The lesson concludes with a note on the specific part of the program that needs modification, preparing students for the next lesson.
