1. INTRO TO ARDUINO @theopak Sept 24, 2014
2. WHAT’S AN ARDUINO?
4. ARDUINO • Microcontroller platform • Open source • You can make cool stuff with it • You program it with the Arduino language 
 using the Arduino software (Mac, PC, or linux)
5. 1. Why use an Arduino? 2. Which type of Arduino? 3. How?
6. 1. Why use an Arduino? 2. Which type of Arduino? 3. How?
7. CASE STUDY: HACKATHON WINNERS • Silicon Chef (Nov 2012) • 4 people • 6 hours • Engineering professors hated it • Engineering professors awarded first place
12. WHY USE AN ARDUINO? • Easier to learn than alternatives. • Widely available for cheap! • Tons of code already exists. • Generally appropriate for real-time. • Not always the best choice, especially because: • Other options have better specs. • Other options use lower power.
14. 1. Why use an Arduino? 2. Which type of Arduino? 3. How?
15. TYPES OF ARDUINOS Nano >$14 ATmega328p small, cheap, breadboardable Leonardo $20 ATmega32u4 cheap, more GPIO Y dual p Linux
16. TYPES OF ARDUINOS Due $50 32-bit ARM tons of GPIO Yún $70 dual processors Linux, WiFi, etc. $20 2u4 GPIO
17. 1. Why use an Arduino? 2. Which type of Arduino? 3. How?
18. Install the Arduino IDE via arduino.cc/en/Main/Software
19. EXAMPLE CIRCUIT: DIGITAL OUTPUT Switch on D5, LED on D13
20. EXAMPLE CODE: FLASH AN LED void setup () { pinMode(13,OUTPUT); } void loop () { // Turn LED on digitalWrite(13,HIGH); delay(100); // Wait 100 milliseconds // Turn LED off digitalWrite(13,LOW); delay(100); // Wait 100 milliseconds }
21. EXAMPLE CODE: BUTTON INPUT void setup () { pinMode(13,OUTPUT); // Configure Pin13 as output pinMode(5,INPUT); // Configure Pin5 as input } void loop () { // If the button is pressed... if (digitalRead(5)) { // ...then turn LED on digitalWrite(13,HIGH); } else { // ...if not, the turn LED off digitalWrite(13,LOW); } }
22. EXAMPLE CODE: SERVO MOTOR #include <Servo.h> Servo myservo; //create servo object to control a servo motor void setup () { myservo.attach(9); //attach pin 9 to the servo object } void loop () { for (int i = 0; i < 255; i ++) { // set the servo position myservo.write(i); // generate PPM signal // wait for the servo to get there delay(15); } }
