帮我用Arduino在mega2560开发板上写一个代码，流程如下流程： 无限循环 {0、等待2秒 两个升降电机SG90复位 1、等待0.5秒 1602屏幕显示 “Hello :)” 直到显示下一项内容时更新 条件循环 直到按下按钮2 { 2、当按下按钮1时 等待2秒 使用颜色传感器TCS34765扫描+写入变量 3、用l298n控制两个步进电机旋转（一正一反）3秒 4、等待1秒 电磁铁通电 等待0.5秒 5、翻页电机SG90旋转170度 6、电磁铁断电 等待0.5秒 7、翻页电机复位 等待0.5秒 8、升降电机旋转10度 等待0.5秒 9、屏幕显示 刚刚读取的变量 直到显示下一项内容时更新 } 10、升降电机降至最低 11、屏幕显示未被写入的变量 等待10秒}

以下是您要求的Arduino代码：

#include <Wire.h>
#include <Adafruit_TCS34725.h>
#include <Stepper.h>
#include <Servo.h>
#include <LiquidCrystal.h>

#define STEPS 200
#define BUTTON1 2
#define BUTTON2 3
#define MOTOR1 8
#define MOTOR2 9
#define SERVO 10
#define MAGNET 11
#define SDA A4
#define SCL A5

Adafruit_TCS34725 colorSensor = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_50MS, TCS34725_GAIN_4X);
Stepper stepper1(STEPS, MOTOR1, MOTOR2);
Servo servo1;
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);

void setup() {
pinMode(BUTTON1, INPUT_PULLUP);
pinMode(BUTTON2, INPUT_PULLUP);
pinMode(MAGNET, OUTPUT);
servo1.attach(SERVO);
lcd.begin(16, 2);
lcd.print("Hello :)");
delay(500);
}

void loop() {
delay(2000);
servo1.write(0);
stepper1.setSpeed(100);
stepper1.step(-STEPS);
lcd.clear();
lcd.print("Press button 2");
while (digitalRead(BUTTON2) == HIGH) {}
lcd.clear();
lcd.print("Press button 1");
while (digitalRead(BUTTON1) == HIGH) {}
delay(2000);
uint16_t r, g, b, c;
colorSensor.getRawData(&r, &g, &b, &c);
lcd.clear();
lcd.print("Color: ");
lcd.print(r);
lcd.print(",");
lcd.print(g);

lcd.print(b);
lcd.setCursor(0, 1);

stepper1.setSpeed(100);
stepper1.step(STEPS);

delay(500);
digitalWrite(MAGNET, LOW);
delay(500);
servo1.write(0);
delay(500);
stepper1.setSpeed(100);
stepper1.step(STEPS/20);
lcd.clear();
lcd.print("Color: ");
lcd.print(r);

lcd.print("Not written: ");
