標(biāo)題: Arduino 1602時(shí)鐘計(jì)數(shù)器程序+接線照片
1602時(shí)鐘計(jì)數(shù)器接線照片見附件。程序代碼：在Mixly1.1.5軟件編譯通過。

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

volatile int hour;
volatile int min2;
volatile int second;
String number;
LiquidCrystal_I2C mylcd(0x27,16,2);

String conversion(int x) {
  number = x;
  if (x < 10) {
number = String("0") + String(x);

  }
  return number;
}

void setup(){
  hour = 0;
  min2 = 0;
  second = 0;
  number = "";
  mylcd.init();
  mylcd.backlight();
}

void loop(){
  delay(1000);
  second = second + 1;
  if (second == 60) {
min2 = min2 + 1;
second = 0;

  }
  if (min2 == 60) {
hour = hour + 1;
min2 = 0;

  }
  if (hour == 24) {
hour = 0;
min2 = 0;
second = 0;

  }
  mylcd.setCursor(0, 0);
  mylcd.print("CLOCK :");
  mylcd.setCursor(0, 1);
  mylcd.print(String(String((conversion(hour))) + String(":")) + String(String((conversion(min2))) + String(":")) + String(conversion(second)));

}
