I'm building one of those arcade style basketball games where you get 30 seconds to shoot a bunch of mini basketballs. I have everything built except the sensor that detects when you sink a basket. I thought the best way to do it would be to have a beam of infrared light interrupted by the ball falling. The switch can be momentary (well, as long as it's at least 100 milliseconds or so), as the software can interpret it from there.
Does anyone have any tips?
I found this circuit, and tried building it, but I'm not getting any reaction from it:

I'm pretty new to circuits and have never built one using an IC, so it's entirely possible the problem is with me. But in this circuit, the light gap is very small (the width of a quarter). Do you think it would be adaptable to 2 feet or so?
Thanks for any help.
And if anyone's curious how I made the game interface with the PC, I used a Phidget interface, and wrote the game in Flash.
