Sean's Arduino Projects

I looked inside the arduino box and pulled out the parts bag and found these

photocell.jpg

Immediately i thought of the “worlds most useless invention” where you flick a switch, and it turns on a motor, that opens the box, a “finger” flicking the switch the other way, and the finger goes back in the box.

My idea is to point an LED at the photocell, and when I push the button, it turns on the led, which then activates the photocell, and 1 second later, the activation of the photocell then turns off the led, and you can press the button and do it all over again.
