🧪 Example Application: Arduino Water Pump Control
Use a relay module or transistor (e.g., BC547 or IRF540N) to switch the pump safely using an Arduino pin.
int pumpPin = 7;
void setup() {
pinMode(pumpPin, OUTPUT);
}
void loop() {
digitalWrite(pumpPin, HIGH); // Pump ON
delay(5000);
digitalWrite(pumpPin, LOW); // Pump OFF
delay(5000);
}
