我的继电器开关出现问题。我有一个5V，四个继电器开关，用于Arduino。我试图做到这一点，当我按下一个按钮时，一个继电器继续，然后，当我再次按下它时，同一个继电器熄灭。
使用一个中继时，此概念适用于代码。但是，问题是我的代码仅适用于一个中继和一个中继。如果我更改代码并生成多个变量，它将无效。
仅供参考，我使用的是Arduino UNO R3 ATmega 328
请记住，第一个代码确实有效，但只适用于一个中继。当我按下按钮将其打开然后再次按下该按钮将其关闭时，它可以正常工作。
const int rl1 = 7;
const int rl2 = 12;
const int rl3 = 2;
const int rl4 = 8;
const int button1 = 11;
const int button2 = 10;
const int button3 = 3;
const int button4 = 4;
int rl1State = LOW;
int rl2State = LOW;
int rl3State = LOW;
int rl4State = LOW;
int buttonState = LOW;
int lastButtonState = HIGH;
int reading;
long lastDebounceTime=0;
long debounceDelay = 50;
void setup() {
Serial.begin(9600);
pinMode(rl1, OUTPUT);
pinMode(rl2, OUTPUT);
pinMode(rl3, OUTPUT);
pinMode(rl3, OUTPUT);
pinMode(button1, INPUT);
pinMode(button2, INPUT);
pinMode(button3, INPUT);
pinMode(button4, INPUT);
}
void loop() {
reading = digitalRead(button1);
if(reading != lastButtonState){
lastDebounceTime = millis();
lastButtonState = reading;
}
if((millis() - lastDebounceTime) > debounceDelay){
if(buttonState != lastButtonState){
buttonState = lastButtonState;
if(buttonState == HIGH){
rl1State = !rl1State;
digitalWrite(rl1, rl1State);
}
}
}
}
我为多个继电器尝试了这个代码：
const int rl1 = 7;
const int rl2 = 12;
const int rl3 = 2;
const int rl4 = 8;
const int button1 = 11;
const int button2 = 10;
const int button3 = 3;
const int button4 = 4;
int rl1State = LOW;
int rl2State = LOW;
int rl3State = LOW;
int rl4State = LOW;
//States
int buttonState1 = LOW;
int lastButtonState1 = HIGH;
int buttonState2 = LOW;
int lastButtonState2 = HIGH;
int buttonState3 = LOW;
int lastButtonState3 = HIGH;
int buttonState4 = LOW;
int lastButtonState4 = HIGH;
//Read State
int reading1;
int reading2;
int reading3;
int reading4;
long lastDebounceTime1=0;
long debounceDelay1 = 50;
long lastDebounceTime2=0;
long debounceDelay2 = 50;
long lastDebounceTime3=0;
long debounceDelay3= 50;
long lastDebounceTime4=0;
long debounceDelay4 = 50;
void setup() {
Serial.begin(9600);
pinMode(rl1, OUTPUT);
pinMode(rl2, OUTPUT);
pinMode(rl3, OUTPUT);
pinMode(rl3, OUTPUT);
pinMode(button1, INPUT);
pinMode(button2, INPUT);
pinMode(button3, INPUT);
pinMode(button4, INPUT);
}
void loop() {
reading1 = digitalRead(button1);
reading2 = digitalRead(button2);
reading3 = digitalRead(button3);
reading4 = digitalRead(button4);
//Relay 1
if(reading1 != lastButtonState1){
lastDebounceTime1 = millis();
lastButtonState1 = reading1;
}
if(reading1 != lastButtonState1){
lastDebounceTime1 = millis();
lastButtonState1 = reading1;
}
if((millis() - lastDebounceTime1) > debounceDelay1){
if(buttonState1 != lastButtonState1){
buttonState1 = lastButtonState1;
if(buttonState1 == HIGH){
rl1State = !rl1State;
digitalWrite(rl1, rl1State);
}
}
}
//Relay 2
if(reading2 != lastButtonState2){
lastDebounceTime2 = millis();
lastButtonState2 = reading2;
}
if((millis() - lastDebounceTime2) > debounceDelay2){
if(buttonState2 != lastButtonState2){
buttonState2 = lastButtonState2;
if(buttonState2 == HIGH){
rl2State = !rl2State;
digitalWrite(rl2, rl2State);
}
}
}
}
我还试图为每个按钮和继电器重新制作所有变量，但它仍然不起作用。
另一方面，我的一个继电器在放入任何引脚时都没有工作（当所有引脚都已连接时），但只有当其中一个引脚断开时才能工作。这真的很奇怪。我测试了继电器，它很好，我改变了Arduino，但仍然有同样的问题。

AH！这将在这里工作的是所有有这个问题的人的代码和原理图（在互联网上看到很多确实有这个问题），以及谢谢你帮助解决这个问题！享受！
