Question

Build a circuit that contains two push buttons, an LED, and any other basic components you think you need. The LED should only light when both push buttons are pressed. Use your Arduino for power and ground. Submit your final code, fritzing breadboard diagram and a video on canvas.

Answer 1

Answer

Here is your answer, if you have any doubt i am here to help you. please comment.

Here is your aurduino code, and circute for the above porblem. You can create it's your own Fritzing software. I created this circute and sketch in Tinkercad.

Here is the sketch and digram,

Component Required

Arduino Uno
resistors  :3
LED        :1
Push Button:2

Arduino sketch

/* connect two push button in digital pin, here 2 and 3.
   LED connected to the digital pin 13.*/
//this variable for reading the value in push button
int p1 = 0; 
int p2 = 0;
void setup()
{
  //initilize the all pin.Which used for input and which used for output
  pinMode(2, INPUT);
  pinMode(3, INPUT);
  pinMode(13, OUTPUT);
}
//this function is used to wait the input from each button.
int buttonWait(int buttonPin){
  int buttonState = 0;
  while(1){
    buttonState = digitalRead(buttonPin);
    if (buttonState == HIGH) {
      return buttonState; //when button press high it will return high, else this will execute this while infinity, similar to loop()
    }
  }
}
void loop()
{
  p1 = buttonWait(2); //wait for the p1 value is high.
  p2 = buttonWait(3); //wait for the p2 value is high
  if(p1 == HIGH && p2==HIGH) //if both high then only blink led
  {
    digitalWrite(13, HIGH);
    delay(500);
  }
  digitalWrite(13,LOW);  //after some second it will unblink
}

Any doubt please comment, i am here to help you.

Thanks in advance
