Arduino for Beginners - 2022 Complete Course - Set a Digital Value - Power On an LED

The video tutorial explains how to set up an LED on pin 12 using a microcontroller. It covers defining constants for easy pin access, setting the pin mode to output, and writing a program to make the LED blink. The tutorial includes steps for configuring the pin, setting initial states, and implementing a loop for blinking with delays. Finally, it demonstrates uploading and executing the program to observe the LED behavior.

Why is it beneficial to define a constant for the LED pin number in your code?

• It increases the brightness of the LED.

• It reduces the power consumption of the LED.

• It allows for easier changes to pin assignments.

• It makes the code run faster.

What is the purpose of the PIN mode function in the context of this tutorial?

• To set the brightness of the LED.

• To set the pin as either input or output.

• To start the LED blinking.

• To define the pin number for the LED.

What is the default state of a pin when it is set as an output?

• Undefined

• Blinking

• Low

• High

How long is the LED initially powered on before it starts blinking in the example?

• 1 second

• 2 seconds

• 3 seconds

• 5 seconds

What is the delay time used between changing the LED state from low to high in the blink example?

• 100 milliseconds

• 250 milliseconds

• 500 milliseconds

• 1000 milliseconds
