最近開始學著使用Arduino來做一些簡單的控制，對於只學商完全不懂電子、電路的人真的是一大福音！很快就能上手～
當然最終還是希望能與電腦做搭配控制，寫了個簡單的程式控制紅、黃、綠燈，並在LCD液晶顯示器顯示目前亮的是Red/Yellow/Blue LED.
[c]
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 16, 2);
int redled =10;
int yellowled =7;
int blueled =4;
void setup()
{
Serial.begin(9600);
pinMode(redled, OUTPUT);
pinMode(yellowled, OUTPUT);
pinMode(blueled, OUTPUT);
lcd.begin();
lcd.clear();
lcd.backlight();
lcd.print("Lin Shou Shan");
}
void loop()
{
char s;
if (Serial.available()>0){
s=(char) Serial.read();
lcd.clear();
digitalWrite(redled, LOW);
digitalWrite(yellowled, LOW);
digitalWrite(blueled, LOW);
if(s==’R’){
digitalWrite(redled, HIGH);
lcd.print("Red LED");
}
if(s==’Y’){
digitalWrite(yellowled, HIGH);
lcd.print("Yellow LED");
}
if(s==’B’){
digitalWrite(blueled, HIGH);
lcd.print("Blue LED");
}
}
}
