Light Inducing Seizure Warning System

In 1997, a Pokemon episode was banned since the flashing lights in the episode caused seizures in many Japanese Children. Inspired by this event, this is a photosensor mount on someone's glasses to detected the light sources in front of a subject that could be seizure inducing and send a warning signal to a user by buzzer.

* Arduino

* Photosensor

* Buzzer

Tools:

* Hot glue gun and hot glue

* Soldering Iron and solder

Solder a voltage divider onto the photoresistor as shown above.

* Solder a 10kΩ resistor onto one of the terminals.

* On this same terminal, solder a wire.

* Solder another wire onto the other pin of the photresistor

Follow the table below for the connections between of the photosensor and the buzzer to the Arduino

* Order of pins do not matter for the buzzer

** The Arduino board has at least 3 GND pins

Upload the following code to the Arduino.

//cosntants for the pins where sensors are plugged into.
const int sensorPin = 0;
const int buzzPin = 9;

unsigned long minute1; 
float time1;

//Set up some global variables for the light level an initial value.
int dark;  // initial value
int lightVal;   // light reading

void setup()
{
  // We'll set up the LED pin to be an output.
  dark = 300;
  //we will take a single reading from the light sensor and store it in the lightCal        //variable. This will give us a prelinary value to compare against in the loop
}

void loop()
{

  lightVal = analogRead(sensorPin); // read the current light levels

  //if lightVal is less than our initial reading withing a threshold then it is dark.

    while (lightVal > dark) {  // still sitting
    tone (buzzPin, 1000, 100);
    delay (100);
    noTone(buzzPin);  }
  }
