IR Beam issues. Answered
So I have been working on an airsoft tripwire type thing. I have the circuit entirely finished. I am using an infrared photoresistor and the one problem I am having is that I can't seem to focus the beam from the IR leds very well. I have three of these (http://superbrightleds.com/specs/IR2030_specs.htm) at my disposal. The IR leds are a pain to line up with the resistor on the circuit. So I ask you, what do you think I could do? Ideas on better ways to focus the beam as well as perhaps ideas for replacing the photoresistor are appreciated. The IR photoresistor came from radioshack. I'm pretty sure this is it: http://www.radioshack.com/product/index.jsp?productId=2049723?
