Arduino Introduction

It is a small development board with a brain (also known as a microcontroller) that you can connect to electrical circuits.

• Motherboard

• Arduino

• Central Processing Unit (CPU)

• Processor

This is where you store your programs to tell the Arduino what to do.

• Digital Pins

• Microcontroller

• Analog Pin

• Power ON LED

How many digital pins has Arduino Uno have?

• 11

• 12

• 13

• 14

This pins are labeled from A0 to A5 and are often used to read analog sensors.

• Digital Pins

• Analog Pins

• Power Pins

• PWM Pins

The Arduino provides 3.3V or 5V through these pins. This is really useful since most components require 3.3V or 5V to operate. The pins labelled as “GND” are the ground pins.

• Digital Pins

• Power ON LED

• Analog Pins

• Power Pins

When you press this button, the program that is currently being run in your Arduino restarts.

• Reset button

• Power Button

• Power Pin

• Power ON LED

This will be on since power is applied to the Arduino.

• Power ON LED

• Power Jack

• USB Jack

• Power Pins

In Arduino, IDE stands for _________________.

• Integrated Development Environment

• Integrated Device Environment

• International Development Environment

These are digital pins marked with a ~ (pins 11, 10, 9, 6, 5 and 3). It allows the digital pins output “fake” varying amounts of voltage.

• TX Pins

• PWM Pins

• RX Pins

• Power Pins

You can power the Arduino through the __________.

• Power Pin

• Power ON LED

• Power Jack

• Analog Pins
