Visual Memory

Photographs capture visual 'memories'.

To incorporate photography into this project a dgital camera hack could be used.

These are some interesting links

This was the most useful as it illustrated the correct way to use a transistor.

There was also some useful sample code which involves turning on and off digital pins as per my own experimentation code.

int CamPin = 8; // Cam trigger connected to digital pin 8

// The setup() method runs once, when the sketch starts

void setup() {
// initialize the digital pin as an output:
pinMode(CamPin, OUTPUT);
digitalWrite(CamPin, LOW); // set the CAM trigger off
}

// the loop() method runs over and over again,
// as long as the Arduino has power

void loop()
{
digitalWrite(CamPin, HIGH); // set the CAM trigger on, capture image
delay(1000); // wait for a second
digitalWrite(CamPin, LOW); // set the CAM trigger off
delay(4000); // wait for 4 seconds
}

They build upon knowledge gained from my mp3 player hack experimentation.

A system could be created which captures memories. The arduino is great at interfacing with hardware despite not having a huge amount of on-board processing power!
