Hi,大家好。小弟是新人發(fā)帖， 我想做一個(gè)Project 用Arduino記錄兩個(gè)開(kāi)關(guān)的按鍵次數(shù)并且用LCD顯示出來(lái)，如果哪個(gè)按鍵次數(shù)多，哪個(gè)led神燈就亮。時(shí)間限制大概在一分鐘左右。 也就是說(shuō)一分鐘之后比較兩個(gè)開(kāi)關(guān)的按鍵次數(shù)借此來(lái)決定打開(kāi)哪個(gè)LED燈。有大神有代碼嗎？
這是計(jì)時(shí)器的代碼：
#include <LiquidCrystal.h>
LiquidCrystal lcd(7,8,9,10,11,12);
int runTimer = 1;
int runFor = 20; // time in seconds
int buzzerPin = 13;
int relayPin=4;
int data = 0;
void setup() {
pinMode(buzzerPin, OUTPUT);
pinMode(relayPin,OUTPUT);
lcd.begin(16, 2);
}
void loop() {
if(runTimer == 1){
digitalWrite(relayPin,LOW); // relay is OFF during countdown
lcd.clear();
lcd.print("TIMER=");
//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(0,0);
lcd.clear();
lcd.print(" TIMER OUT!");
}
這是記錄開(kāi)關(guān)按鍵次數(shù)的代碼：
#include <LiquidCrystal.h>
LiquidCrystal lcd(7,8,9,10,11,12);
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() {
// set up the number of columns and rows on the LCD
lcd.begin(16, 2);
pinMode(switchPin,INPUT);
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("Hit the button");
pinMode(switchPin1,INPUT);
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("Hit the button");
}
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;
}
我想把這部分代碼組合到一起， 在倒計(jì)時(shí)的同時(shí)記錄兩個(gè)開(kāi)關(guān)的按鍵次數(shù)。 當(dāng)?shù)褂?jì)時(shí)結(jié)束時(shí)，停止兩個(gè)開(kāi)關(guān)的計(jì)數(shù)。不知道怎么做，總是一個(gè)工作另外一個(gè)就不工作。。求大神解答
