1. Introduction to Arduino
KU1101 Pengantar Rekayasa dan Desain

2. What is Arduino?
 An open-source electronic microcontroller board
 Originally built for designer & artists – people with little technical expertise
 We can easily program to understand and interact with the environment

4. Exploring Arduino Board

5. Minimum Requirement for a Project
 Arduino Board
 USB Cable
 PC with Arduino IDE
 Power Adapter (7V to 12V)

6. Powering Up External Devices
 3.3V and 5V pins to power up external device
 GND to share common ground
 Vin and GND as Arduino power source

7. Analog Signal vs Digital Signal
 Nearly all physical processes are analog.

8. Start an Arduino Project
 Installing Arduino IDE
 Installing the Drivers

9. Arduino IDE
 Verify: check and compile
 Upload: compile and upload program to board
 Serial Monitor: communicate via serial connection with Arduino

10. Hello, World! (not really)
const unsigned int LED_PIN = 13;
const unsigned int PAUSE = 500;
void setup() {
// put your setup code here, to run once:
pinMode(LED_PIN, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(LED_PIN, HIGH);
delay(PAUSE);
digitalWrite(LED_PIN, LOW);
delay(PAUSE);
}

11. Using Serial Ports
const unsigned int LED_PIN = 13;
const unsigned int BAUD_RATE = 9600;
void setup() {
// put your setup code here, to run once:
// Arduino Uno, 0=RX, 1=TX
pinMode(LED_PIN, OUTPUT);
Serial.begin(BAUD_RATE);
}
void loop() {
// put your main code here, to run repeatedly:
if (Serial.available() > 0) {
// read the first byte
int command = Serial.read();
if (command == '1') {
digitalWrite(LED_PIN, HIGH);
Serial.println("LED on");
} else if (command == '2') {
digitalWrite(LED_PIN, LOW);
Serial.println("LED off");
} else {
Serial.print("Unknown command: ");
Serial.println(command);
}
}
}

12. Common Components

13. Binary Dice

14. Push Button
