[版本一]利用序列埠視窗輸入角度
#include <Servo.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x3F,16,2); // 若LCD 無法啟用，請將0X3F 改為0X27
Servo servo;
int x,y,x1,x2;
void setup(){
Serial.begin(9600);
Serial.setTimeout(10); // 設定為每10毫秒結束一次讀取(數字愈小愈快)
servo.attach(8);
lcd.init();
lcd.backlight();
lcd.clear();
lcd.setCursor(0,0);
lcd.print("Servo in D8");
lcd.setCursor(0,1);
lcd.print("Wait command...");
}
void loop(){
while(Serial.available()){
x = Serial.parseInt();
y = Serial.parseInt();
if(x2!=x){
x2 = x ;
}
}
if(x2!=x1){
Serial.print(x);
Serial.print(" , ");
Serial.println(y);
lcd.setCursor(0,0);
lcd.print("Angle = ");
lcd.print(x);
lcd.print(" ");
lcd.setCursor(0,1);
if(y==0){
lcd.print("ok");
lcd.print(" ");
}

}

}
[版本二]利用可變電阻(A0腳位)調整角度(一個servo)
#include <Servo.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x3F,16,2); // 若LCD 無法啟用，請將0X3F 改為0X27
Servo servo;
int x,y,x1,x2,cmd;
void setup(){
Serial.begin(9600);
Serial.setTimeout(10); // 設定為每10毫秒結束一次讀取(數字愈小愈快)
servo.attach(8);
lcd.init();
lcd.backlight();
lcd.clear();
lcd.setCursor(0,0);
lcd.print("Servo in D8");
lcd.setCursor(0,1);
lcd.print("Wait command...");
}
void loop(){
x = int(map(analogRead(A0),0,1022,0,181));
if(x2!=x){
x2 = x ;
}
if(x2!=x1){
