/ Demo 2
/ Conclusion

3. Why ?
• open-source project
• flexible to be customized and extended
• easy to use for beginners
• inexpensive (around 40$)
• strong online community
• lots of free source code

4. MicroView
Arduino Variations
Orangeboard & Dotduino

6. Arduino + 3D printing = Product Prototype
GameTube
Robot DIO
Hanguel clock

7. USB

9. Code Basics
setup()
pinMode()
input, output
loop()
digitalWrite()
HIGH, LOW
analogWrite()
HIGH, LOW
delay()
1000=1sec

10. example
int buttonPin = 3;
void setup()
{
Serial.begin(9600);
pinMode(buttonPin, INPUT);
}
void loop()
{
// ...
}

11. example
// loop checks the button pin each time,
// and will send serial if it is pressed
void loop()
{
if (digitalRead(buttonPin) == HIGH)
Serial.write('H');
else
Serial.write('L');
delay(1000);
}

15. Temperature & Humidity Sensor (DHT11)
• Good for 20-80% humidity readings with 5% accuracy
• Good for 0-50°C temperature readings ±2°C accuracy
• 4 pins with 0.1" spacing (VCC, GND, Data Out)
• 3 to 5V power and I/O
