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 involving an LED and serial communication?

• Choose a random LED pin

• Set up a wireless connection

• Make the LED blink

• Install a new LED

How is the delay for the LED blink initially set?

• By using a default value

• By reading from a file

• By user input through a button

• By adjusting the LED brightness

What function is used to convert serial communication data into a number for the delay?

• stringToInt

• convertToNumber

• assint

• parseInt

What is the acceptable range for the LED blink delay in milliseconds?

• 50 to 1500

• 200 to 1200

• 10 to 1000

• 100 to 1000

What happens if a delay of 1300 milliseconds is sent?

• The LED will stop blinking

• The LED will blink faster

• The input will be accepted

• The input will be rejected
