I'm building a lasertag system, using actual lasers (yes i know, very unsafe, will be played with laser goggles on for extra safety, and laser will only give short pulse)
Ofcourse i need a receiver to detect when you get hit.
I plan on using LDR's, and i'll need quite some to cover enough area on the body.
Now this is also the issue i'm running up against, i need to use as little pins as possible but still need alot of ldrs.
All i need to know is IF light is hitting the ldr, brightness is not important.
What would be the best way to do this? i was planning on putting them in series, but this might make the total resistance too low to read.
Looking forward to your thoughts!
