Arduino 範例程式 - Serial port

硬體配置
   參考範例程式 "Arduino - LED"


程式
-----------------------------------------

-----------------------------------------

開啓 Tools -> Serial Monitor

結果 : 送出 "1", LED 會亮; 送出 "0", LED 會熄滅

Arduino 範例程式 - LED

Ref: http://arduino.cc/en/Tutorial/Blink


這是一個基礎使用 LED 的範例程式

硬體設備

• Arduino Uno Board
• LED

電路

可以使用軟體 Fritzing 來繪製

(1) 選擇 Arduino Uno Board

(2) 加入 LED 

image developed using Fritzing. For more circuit examples, see the Fritzing project page

和以下的範例電路不同, 我沒有另外增加電阻. 這是因為 Atmel 的 ATmega328P 本身內部已有 pull high 線路.

參考

• setup()
• loop()
• pinMode()
• digitalWrite()
• delay()
• BareMinimum: The bare minimum of code needed to start an Arduino sketch.
• Blink: Turn an LED on and off.
• DigitalReadSerial: Read a switch, print the state out to the Arduino Serial Monitor.
• AnalogReadSerial: Read a potentiometer, print its state out to the Arduino Serial Monitor.
• Fade: Demonstrates the use of analog output to fade an LED.
• ReadAnalogVoltage : Reads an analog input and prints the voltage to the serial monitor
