Arduino for Beginners - 2022 Complete Course - Activity 08 - Set an LED Blink Rate from the Serial Monitor

This video tutorial guides students through an activity involving an LED and serial communication. The task is to make an LED blink by setting a delay, which can be adjusted using serial communication. The tutorial covers reading data from serial input, using a default delay value, and validating user input to ensure the delay is between 100 and 1000 milliseconds.

What is the first step in the activity described in the text?

How do you set the frequency of the LED blinking?

Explain how the program handles the initial delay value when it starts.

What range of values is acceptable for the delay in milliseconds?

What should you do if the user inputs a delay value outside the acceptable range?
