Think you have good night vision? This experiment is
a game that lets you find out how well you can see in
t
he dark. In a completely dark room, it tests your aim!
Once you have completed this project, put it in as
dark of a room as possible. Slide the switch to
position A and modify the control in a counter-
clockwise direction until LED 1 and LED 3 light. Now
it is time to test your ability.
For this game your “gun” is a typical flashlight. With
a beam of light you use your flashlight to “shoot” the
kit. If your aim is correct, you’ll hit the CdS cell to
light LED 2 and turn off LED 1 and LED 3. Then turn
off your flashlight and wait until LED 2 goes off
before you try your next shot.
Start off trying to hit the CdS cell from around five
feet or so. You aim will improve as you increase
your distance. Once you get really good, you can try
hitting the CdS cell simply by switching your
flashlight on and off rather than using a continuous
stream of light.
You may have to modify the control knob very
carefully to have LED 2 come on when light strikes
the CdS cell. For the best results, use a sharply
focused flashlight (not a fluorescent lamp or other
light) and be sure you have the kit in a completely
dark room. Once you’ve found the best setting, keep
it there so you can use it again. Don’t change it until
you want to stop using the “shot in the dark” game.
Have fun and good luck J
