写一段程序使LCD1602液晶品示（姓名＋学号)，按下 K1，LCD1602液晶屏第一行显示自己姓名拼音首宇母。按下k2，LCD1602液晶屏第二行显示自己的学号。按下k3，清屏。

以下是程序：

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
lcd.begin(16, 2);
pinMode(6, INPUT_PULLUP);
pinMode(7, INPUT_PULLUP);
pinMode(8, INPUT_PULLUP);
}

void loop() {
if (digitalRead(6) == LOW) {
lcd.setCursor(0, 0);
lcd.print("Your Name");
}
if (digitalRead(7) == LOW) {
lcd.setCursor(0, 1);
lcd.print("Your Student ID");
}
if (digitalRead(8) == LOW) {
lcd.clear();
}
}
