slot cars

Hello all and thanks for the help. Here is my problem!
I need a program that will (on a figure eight slot car set)(using
momentary switches) create a zone around the crash area so that if
one car is running continuously and the other is manually
controlled, stop the continuously running car when the manually run
car is near the crash area. Any ideas. Thanks Rick

Good idea - you can find the IR stuff you need at www.rentron.com.

I'd go optical; place an IR emitter/detector pair across the track before
the controlled car enters the intersection and have it disable the power for
the other car (but only for the section before it enters the intersection
from the other direction).

you have a thought on the direction to take in writing the code.
Thanks Rick

Great idea, we had thought of using momentary switches also. Do

trains, to determine when a train was at a certain track
location.
A modified section of track might do it....
...Make two very small cuts or breaks in the track.
rejoin the cuts with 5 Ohm resistors.
i.e.
o---X---o
o---X---o
| | | |
o--/\/\-o o--/\/\-o
| |
o
>|
o
| reverse biased diodes |
o
|<
o
X = cut in track
Diodes should be rated at least 2X motor current draw
...Now monitor the voltage across each resistor( If
you don't care about direction, just use one resistor)
A voltage spike upward would indicate that a car has entered
the modified track section.
A voltage spike downward would indicate that a car has left
the modified track section.
Speed could be calculated based on the length of track and
duration of time spent on the modified track.
