This document discusses an Arduino introductory project about lighting. It provides instructions on installing the Arduino driver, uploading a basic blinking LED program, and exploring analog input and output by reading the value of a potentiometer and fading an LED. It also introduces Fritzing and 123D Circuits as tools for circuit schematic design.

6. Arduino Introduction
• Massimo Banzi 和 David Cuartielles所設計
• 採用低價位微處理器 ，Atmel Atmega8/168/328 單晶片
• 開放式的軟硬體平台

7. Arduino UNO
USB Port
外接電源（DC）
Digital(PWM )
通訊
Power燈
Reset
類比輸入電壓 in/out

8. Install the Arduino Driver

9. Install the Arduino Driver

10. Getting Started
• 指定Arduino Driver資料夾位置

11. Getting Started
• 打開裝置管理員，將”連接埠”展開，確認USB Serial
Port

12. Getting Started
• 將Arduino.exe打開，在tools下選擇正確的Board與Serial
Port

13. LED Blink
• File >> Examples >> 1.Basics >> Blink

14. LED Blink
• Verify & Upload

Status

15. How does it work?
void setup() {  初始化
}
void loop() {  重複執行
...}

16. How does it work?
int led = 13;
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(led, HIGH); // set the LED on delay(1000);
// wait for a second digitalWrite(led, LOW); // set the LED
off delay(1000); // wait for a second
}

17. 動手寫寫看！

18. 基本範例
(File >> Example >> Basic >> Fade)

19. 程式
int brightness = 0; // how bright the LED is
int fadeAmount = 5; // how many points to fade the
LED by
void setup() { // declare pin 9 to be an output:
pinMode(9, OUTPUT);
}
void loop() { // set the brightness of pin 9:
analogWrite(9, brightness); // change the
brightness for next time through the loop:
brightness = brightness + fadeAmount; // reverse
the direction of the fading at the ends of the fade:
if (brightness == 0 || brightness == 255){
fadeAmount = -fadeAmount ;
} // wait for 30 milliseconds to see the dimming
effect
delay(30);
}

20. 可變電阻

21. 讀取類比腳位狀態
(File >> Example >> Basic>> AnalogReadSerial)
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(A
0);
Serial.println(sensorValue);
delay(1);
}

22. 接線
• 中間：A0~A5
• 一側：5V
• 另一側：GND

23. 可變電阻控制LED漸明漸暗
(File >> Example >> Analog >> AnalogInOutSerial)

24. 光敏電阻
• 一端接A0，一端接地
• 由於是被動元件，需要在A0 那端加上5V
