这是小弟的代码
#include <LiquidCrystal.h>
LiquidCrystal lcd(7,8,9,10,11,12);
int runTimer = 1;
int runFor = 50; // time in seconds
int buzzerPin = 13;
int relayPin=4;
int data = 0;

const int switchPin = 5;
int hits = 0;
int switchState = 0;
int prevSwitchState = 0;

const int switchPin1 = 6;
int hits1 = 0;
int switchState1 = 0;
int prevSwitchState1 = 0;

void setup() {
{

pinMode(buzzerPin, OUTPUT);
pinMode(relayPin,OUTPUT);
lcd.begin(16, 0);
}
{
lcd.begin(16, 2);
pinMode(switchPin,INPUT);

  pinMode(switchPin1,INPUT);

}
}

void loop() {

switchState = digitalRead(switchPin);

  if (switchState != prevSwitchState) {
if (switchState == LOW) {
   hits = hits + 1;
   lcd.clear();
   lcd.setCursor(0, 1);
   lcd.print("Hits:");
   lcd.setCursor(7, 1);
   lcd.print(hits);
   lcd.setCursor(11, 1);
   lcd.print(hits1);
   delay(90);
}
  }
prevSwitchState = switchState;

switchState1 = digitalRead(switchPin1);

  if (switchState1 != prevSwitchState1) {
if (switchState1 == LOW) {
   hits1 = hits1 + 1;
   lcd.clear();
   lcd.setCursor(0, 1);
   lcd.print("Hits:");
   lcd.setCursor(11, 1);
   lcd.print(hits1);
   lcd.setCursor(7, 1);
   lcd.print(hits);
   delay(90);
}
  }
  prevSwitchState1 = switchState1;

if(runTimer == 1){
   digitalWrite(relayPin,LOW); // relay is OFF during countdown

   lcd.clear();
   lcd.print("TIMER=");

   lcd.setCursor(0, 1);
   lcd.print("Hits:");
   lcd.setCursor(7, 1);
   lcd.print(hits);
   lcd.setCursor(11, 1);
   lcd.print(hits1)
   //Start timer
   ;timer();
}
runTimer = 0;
lcd.noDisplay();
delay(250);
for(int duration = 0; duration < 100; duration ++){
   digitalWrite(buzzerPin, HIGH);
   delayMicroseconds(500);
   digitalWrite(buzzerPin, LOW);
   delayMicroseconds(500);
}
lcd.display();
delay(250);
}

void timer() {
for(int timer = runFor;timer > 0; --timer){
if(timer >= 10) {
   lcd.setCursor(6,0);
} else {
   lcd.setCursor(6,0);
   lcd.print("0");
   lcd.setCursor(7,0);
}
lcd.print(timer);
lcd.print(" SECOND!");
delay(1000);
}
lcd.setCursor(1,1);
lcd.clear();
lcd.print(" TIMER OUT!");

   lcd.setCursor(0, 1);
   lcd.print("Hits:");
   lcd.setCursor(7, 1);
   lcd.print(hits);
   lcd.setCursor(11, 1);
   lcd.print(hits1);
}

当我用Arduino UNO 测试时，计时器工作但是开关计计数不工作。。请大神指点
