Story

Many people always dreamed of being a spy or wishing they could have their tech gadgets. Many people also wish to not always have to be watched and be able to have at least some privacy. Well this project does both. This 9 volt powered incognito glasses, inspired by MacGyver, uses infrared(IR) light to block out your face from any security camera that does not have an IR filter by the push of a button. IR light, under most circumstances, cannot be seen by the naked eye. While these glasses may be able to block out security cameras without an IR filter, it cannot block out cameras that do have one such as phones. All you will see is a small red or purple light coming from the LEDs with a camera that has a IR filter. Also if the LEDs are not bright enough it can be quite difficult to actually block out your face. However, these issues can be fixed with brighter IR LEDs. These glasses do not vary in brightness as well with a potentiometer. This is because when blocking out the cameras you will always want the LEDs to either be fully on or not on at all so they can block out your face fully and not partially. Also, if you take out the battery supply with the potentiometer on max and forget you left it on max, the next time you put on the power supply, it

can be wasting unnecessary power. When you use a push button this does not occur because to turn on the LEDs it needs the initial push from the button. This project was made for educational purposes only.

CODE

int buttonState = 0;
int buttonCounter = 0;
void setup()
{
  pinMode(0, OUTPUT); // Transistor
  pinMode(1, INPUT); // Read Pushbutton

}

void loop()
{
  do {

    buttonState = digitalRead(1); // check button

    if (buttonState == HIGH) {
      buttonCounter++;
    }

  } while (buttonState == LOW);



  do {

    buttonState = digitalRead(1);

  } while (buttonState == HIGH);



  if (buttonCounter == 1) { // If buttonCounter = 1, turn on leds
    digitalWrite(0, HIGH);
  }

  else if (buttonCounter == 2) { // If buttonCounter = 2,turn off leds
    digitalWrite(0, LOW);
    buttonCounter = 0;
  }
  delay(20); // helps with simulation
}
