Arduino – sterowanie przekaźnikami

W tym szybkim tutorialu Arduino opiszę w jaki sposób można sterować przekaźnikami za pomocą Arduino. Potrzebne nam będą jeden rezystor 10kΩ, moduł przekaźnika, Po naciśnięciu przycisku nasz przekaźnik włączy się i pozostanie w tym stanie aż do momentu ponownego naciśnięcia przycisku.

Wykaz elementów:

Arduino np. nano
rezystory 10kΩ x8
przyciski x 8
płytka uniwersalna
cyna oraz lutownica

Kod programu (dla 1 przekaźnika)

int pinButton1 = A0;
int Relay1 = 2;

int stateRelay1 = HIGH;

int stateButton1;

int previous = LOW;
long time = 0;
long debounce = 500;

void setup() {
pinMode(pinButton1, INPUT);
pinMode(Relay1, OUTPUT);
}

void loop() {
stateButton1 = digitalRead(pinButton1);
if(stateButton1 == HIGH && previous == LOW && millis() – time > debounce) {
if(stateRelay1 == HIGH){
stateRelay1 = LOW;
} else {
stateRelay1 = HIGH;
}
time = millis();
}
digitalWrite(Relay1, stateRelay1);
previous == stateButton1;

}

Docelowo potrzebowałem wysterować 8 przekaźnikami.Wszystko w celu rozbudowy już istniejącej automatyki domowej.
