Arduino Basics

Front

What is the purpose of the Arduino?

Back

It’s an excellent tool for beginners and students to learn about electronics, programming, and robotics.

Front

What components are included in the Arduino board?

Back

Reset button, USB port, voltage regulator, power port, built-in LEDs, digital I/O pins, power and ground pins, analog pins.

Front

What does the reset button do on the Arduino?

Back

It restarts the code currently uploaded on the Arduino.

Front

What is the function of the USB port on the Arduino?

Back

It connects the Arduino to a computer for programming and provides power if not using the power port.

Front

What type of power sources can the power port accept?

Back

Power from a wall source (wall-wart) or from a battery.

Front

What do the built-in LEDs indicate?

Back

They indicate that there is power and if the Arduino is sending or receiving data.

Front

What are digital I/O pins used for?

Back

They are used to sense the outside world (input) or control lights, sounds, or motors (output).

Front

What can power and ground pins be used for?

Back

To run power from the Arduino to a breadboard circuit.

Front

What do analog pins do?

Back

They take sensor readings in a range of values (analog), rather than just on or off (digital).

Front

What is resistor?

Back

A resistor in Arduino (and in general electronics) is a component that resists the flow of electrical current.
