  1. Exploring the Arduino Board Khaled A. Al-Utaibi alutaibi@uoh.edu.sa

  2. Agenda • What is Arduino? • Arduino Boards • Arduino Shields • Arduino Uno Hardware

  3. What is Arduino? • Arduino is a single-board open-source platform for building electronic projects

  4. What is Arduino? • Arduinoconsists of two components: • (1) a physical programmable circuit board designed around an Atmel microcontroller, and • (2) an Integrated Development Environment (IDE)which is used to write the code on a computer, and then upload it to the physical board.

  5. What is Arduino? • Arduinodoes not need a separate piece of hardware (called a programmer) to load new code onto the board – you can simply use a USB cable.

  6. What is Arduino? • ArduinoIDE uses a simplified version of C++, making it easier to learn to program.

  7. Arduino Boards • Arduino provides many alternative boards. • These boards vary in the following aspects: • the microcontroller type, • The microcontroller speed (frequency) • the physical size, • the number of input and output pins, • the memory space for programs, and • the board price.

  8. Arduino Boards • Examples of Ardunio boards include: Arduino Uno Arduino Leonardo Arduino Due Arduino Micro Arduino Mega 2560 ArduinoNano

  10. Arduino Shields • We can add functionality to an Arduino board by attaching shields. • Ashieldis a circuit board that connects via pins to the sockets on the sides of an Arduino. • Hundreds of shields are available on the market. • Examples of these shields include: • GSM Shield • Ethernet Shield • WiFiShield

  11. Arduino ShieldsGSM Shield • The GSM Shieldwith a SIM card allows an Arduino board to connect to the internet, make/receive voice calls and send/receive SMS messages.

  12. Arduino Shields Ethernet Shield • The Ethernet Shield allows an Arduino board to connect to the internet. It provides a network (IP) stack capable of both TCP and UDP.

  13. Arduino ShieldsWiFi Shield • The WiFiShield allows an Arduino board to connect to the internet using the 802.11 wireless specification (WiFi). It provides a network (IP) stack capable of both TCP and UDP.

  14. The Arduino Starter Kit • The kit includes Arduino UNO board and a selection of the most common electronic components with a book of 15 projects.

  20. Arduino UNO HardwareOverview • The Arduino Uno is a microcontroller board based on the ATmega328. • It has the following main parts: • an ATmega382 microcontroller, • a 16MHz clock, • 14digital input/output pins (of which 6 can be used as PWM outputs), • 6 analog inputs, • an ICSP header, • a USB connection, • a power jack • a reset button, and • on board LEDs

  22. Arduino UNO HardwareThe USB & Power Connectors • The Universal Serial Bus (USB) connector connects the board to a computer for three reasons: • (1) to supply power to the board • (2) to upload code to the Arduino • (3) to send data to and receive it from a computer. • The Power Connector is used to power the Arduino with a standard mains power adapter.

  23. Arduino UNO HardwareThe Microcontroller • The microcontroller is a special type of processors that … • includes various types of memory to hold data and programs, • executes instructions, and • provides various means of sending and receiving data.

  24. Arduino UNO HardwareThe Power Pins • This row of pins offers power connections and the ability to use an external RESET button. • The power pins are as follows: • VIN: This pin is used to receive input voltage to the Arduino board when it's using an external power source. • 5V:This pin outputs a regulated 5V from the regulator on the board. • 3.3V: This pin outputs a regulated 3.3V from the regulator on the board. • GND.This pin provides the Ground signal. • IOREF:This pin on the Arduino board provides the voltage reference with which the microcontroller operates.

  25. Arduino UNO HardwareThe Analog Pins • This row of pins offers six analog inputs that are used to measure electrical signals that vary in voltage. • Furthermore, pins A4 and A5 can also be used for sending data to and receiving it from other devices.

  26. Arduino UNO Hardware The Digital Input/Output Pins • Pins numbered 0 to 13 are digital input/output (I/O) pins. • Pins 0(RX) and 1(TX) are also known as the serial port, which is used to send and receive serial data to other devices. • The pins labeled with a tilde (~) can also generate a varying electrical signal (PWM).
