The circuit is still same with Controlling Led with more than 1 input using OR or AND logic. Now we can try to vary of using of OR and AND logic. At this example we want to use 4 inputs (the inputs are still push button), we will make programming so that Led will ON when 2 of 4 push buttons are pressed.
The sketch is as follows:
int ledPin = 13;
int inPin1 = 2;
int inPin2 = 3;
int inPin3 = 4;
int inPin4 = 5;
int val1 = 0;
int val2 = 0;
int val3 = 0;
int val4 = 0;
void setup {
pinMode(ledPin, OUTPUT);
pinMode(inPin1, INPUT);
pinMode(inPin2, INPUT);
pinMode(inPin3, INPUT);
pinMode(inPin4, INPUT);
}
void loop() {
val1 = digitalRead(inPin1);
val2 = digitalRead(inPin2);
val3 = digitalRead(inPin3);
val4 = digitalRead(inPin4);
if ((val1 == HIGH && val2 == HIGH || val1 == HIGH && val3 == HIGH ||
val1 == HIGH && val4 == HIGH || val2 == HIGH && val3 == HIGH ||
val2 == HIGH && val4 == HIGH || val3 == HIGH && val4 == HIGH)) {
digitalWrite(ledPin, HIGH);
} else {
digitalWrite(ledPin, LOW);
}
}
Now, friends already can vary it, can't you...?
The sketch above is controlling Led in which Led will ON if AT LEAST 2 push buttons are pressed, it means if 3 push buttons are pressed or 4 push buttons are pressed then LED will still ON, how if we want LED will ON if only 2 push buttons are pressed? so if 1 push buttons is pressed, or 3 push buttons are pressed or 4 push buttons are pressed then LED will OFF, approximately the what is the sketch like...?
