Arduino Basics and Blinking LED Project

What is one of the unique features of Arduino that makes it popular among artists and hobbyists?

• It is user-friendly and versatile.

• It is the most expensive microcontroller.

• It requires advanced programming skills.

• It can only be used for robotics.

Which component is NOT required for the blinking LED project?

• Breadboard

• Resistor

• A to B USB cable

• Arduino board

What is the function of the shorter leg of an LED?

• Connects to the microcontroller

• Connects to the power supply

• Connects to ground

• Connects to the positive voltage source

How are the rows and columns connected on a breadboard?

• Rows are connected vertically, columns horizontally

• Rows are connected horizontally, columns vertically

• Both rows and columns are connected vertically

• Both rows and columns are connected horizontally

What is the purpose of the 'setup' function in Arduino programming?

• To run the code continuously

• To turn off the Arduino

• To configure initial settings and run once

• To upload the code to the Arduino

In the loop function, what happens when a pin is set to 'high'?

• The program stops

• The LED turns off

• The LED turns on

• The Arduino resets

What is the final step to make the LEDs blink after writing the code?

• Disconnect the USB cable

• Upload the sketch to the Arduino

• Turn off the Arduino

• Remove the LEDs

How can you make the LEDs blink faster in the code?

• Add more LEDs

• Decrease the delay value

• Increase the delay value

• Remove some LEDs

What is the advantage of using Arduino for projects?

• It requires a lot of time to set up

• It is only compatible with specific components

• It allows easy software changes for different effects

• It is difficult to modify the code

What is the primary role of the Arduino software in this project?

• To provide power to the LEDs

• To write and upload code to control the hardware

• To physically assemble the components

• To connect the Arduino to the internet
