Question

write a program using arduino , in which the water pump start and stop every 2 1/2 minutes. ( can you post the results from the output please)

Answer 1

int buttonPin1 = 2; //Start button
int buttonPin2 = 3; //Stop button
int greenLedPin = 6;//green led start status int
redLedPin = 7; //red led stop status int motorPin = 9; // the motor's pin
int buttonStatus1 = 0;
int buttonStatus2 = 0;

void setup() {
pinMode(motorPin, OUTPUT);
pinMode(greenLedPin, OUTPUT); pinMode(redLedPin, OUTPUT);
pinMode(buttonPin1, INPUT);
pinMode(buttonPin2, INPUT);
}
void loop() {
buttonStatus1 = digitalRead(buttonPin1);
buttonStatus2 = digitalRead(buttonPin2);

if (buttonStatus1 == HIGH && buttonStatus2 == LOW) { // if the start button is pressed (AND stop button not) digitalWrite(motorPin, HIGH);// turn the motor ON
digitalWrite(greenLedPin, HIGH); //turn the green led indicator ON
digitalWrite(redLedPin, LOW); //turn the red led indicator OFF }

if (buttonStatus1 == LOW && buttonStatus2 == HIGH) { // if stop button is pressed (AND the start off)
digitalWrite(motorPin, LOW); // turn the motor OFF
digitalWrite(greenLedPin, LOW); //turn the green led indicator OFF
digitalWrite(redLedPin, HIGH); //turn the red led indicator ON
}
}
