What is Arduino?


Arduino

• Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.

• It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.


Arduino

• Arduino Board– ATMega328– USB– Open Source

• Arduino IDE(Integrated Development Environment)– Windows, Linux, Mac OSX– Opern Source– Based on Processing

• Arudino Programming language– Based on Wiring

Setup(Mac OS X)

• Tools-> Board-> Arduino UNO• Tools->Serial Port -> /dev/tty.usbserial-xxxxxxxx


Hello (Physical) World!


Test

1. Open a example file.Menu->File->Examples->Basics->Blink


Hello World!

void setup() { // initialize the digital pin as an output. // Pin 13 has an LED connected on most Arduino boards: pinMode(13, OUTPUT); }

void loop() { digitalWrite(13, HIGH); // set the LED on delay(1000); // wait for a second digitalWrite(13, LOW); // set the LED off delay(1000); // wait for a second}

PWM

• PWM(Pulse Width Modulation)

Ｄ = τ/ TD : duty cycleτ: pulseT ： transition


ex: 0.25(D) = 1(τ)/4(T)

Basis of Electrical Circuit


Basic Knowledge

• Voltage – The difference in electric potential between

two points.– Unit symbol V(Volt)

• Electric current – A flow of electric charge through a medium.– Unit symbol A(Ampere)

• Resistance – The opposition to the passage of an electric

current.– Unit symbol Ω(Ohm)

Arduino Digital Pin

Control using servo library

Methods see… http://www.arduino.cc/en/Reference/Servo– attach(pin/number)

• Attach the Servo variable to a pin– write(angle/degrees 0 - 180)– writeMicroseconds(time/micro seconds1250 - 1750)– read(pin/number)

• The angle of the servo, from 0 to 180 degrees. – attached()

• Use as ServoObject.attached() returns true/false – detach()

• Use as ServoObject.detach() detach pin from servo

#include <Servo.h> //a maximum of eight servo objects can be created

Servo myservo; // create servo object to control a servo int pos = 0; // variable to store the servo position void setup() { myservo.attach(9); // attaches the servo on pin 9 to the servo object } void loop() { for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees { // in steps of 1 degree myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees { myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } }
