Q & A

What is Arduino?

Arduino is an open-source programmable circuit board and microcontroller that allows users to build digital hardware products. It was first introduced in Italy in 2005.

How many Arduino boards have been sold worldwide?

As of today, over 10 million Arduino boards have been sold worldwide.

What is the most popular Arduino model?

The most popular Arduino model is the Uno.

What is a microcontroller, and why is it important for Arduino?

A microcontroller is a small, inexpensive computer that can run on low power. It is crucial for Arduino because it processes the code and controls the hardware connected to the board.

What is a sketch in Arduino?

A sketch is a software program in Arduino, written in a purpose-built, easy-to-learn programming language.

What are the two basic functions in every Arduino program?

Every Arduino program has two basic functions: 'setup,' which runs once when the board is powered on, and 'loop,' which runs continuously to react to input signals or changes in the program.

What types of hardware projects can be built with Arduino?

Arduino can be used to build IoT products, robots, wearable devices, and a wide range of other hardware projects.

How do you upload code to an Arduino board?

To upload code to an Arduino board, you connect it to a computer via USB, write a sketch (a file ending in .ino), and press the upload button to compile and run the code.

How can you control an LED with Arduino?

You can control an LED by using the built-in 'pinMode' function to configure the pin connected to the LED as an output. In the loop function, you can turn the LED on by writing a HIGH value to the pin and off by writing a LOW value.

What components can be connected to Arduino using a breadboard?

You can connect components like LEDs, capacitors, resistors, motors, switches, and more to Arduino using a breadboard. These components are controlled in the code by referencing the pin numbers they are connected to.
