Arduino for Beginners - 2022 Complete Course - How Digital Pins Work as Input Pins

The video tutorial explains how to use digital pins in electronic circuits. It covers setting the pin mode to output or input, and how to change or read the pin state. The tutorial highlights that digital pins can only read binary values when set as input. Practical examples, such as using a push button, are provided to illustrate these concepts.

What is the first step in using a digital pin?

• Change its state

• Read its value

• Connect it to a power source

• Set its mode

What can you do when a digital pin is set to input mode?

• Set an analog value

• Read a digital value

• Change the pin state

• Connect to another pin

What voltage level corresponds to a 'high' state on a digital pin?

• 0 Volt

• 5 Volt

• 10 Volt

• 2.5 Volt

Can you read analog values from a digital pin set as input?

• Yes, always

• No, only when the pin is set to output

• No, only binary values

• Yes, but only with special components

How can you determine if a push button is pressed using a digital pin?

• Observe the LED indicator

• Measure the current

• Check if the pin state is high

• Check if the pin state is low
