Gravity: IR Positioning Camera for Arduino - 4-Point Tracking Sensor, 128x96 Pixels for Flame Detection, Robot Navigation, STEM Projects​

For anyone making any gun4ir arcade gun this this the camera for you

I bought a couple of these for some Gun4ir builds. If you haven't checked out that tech before, it's worth taking a look at. It's software that allows you to play old light-gun games (like Duck Hunt and many others) on modern TVs using infrared lights positioned around the TV. Both cameras I ordered worked as the should. I do wish the 'top' was better labeled as mine both slightly different. It wasn't a big issue, just a matter of ensuring it was set correctly before completing assembly.

This is a really interesting sensor to play with, make sure you know what orientation the camera sensor itself is (i.e. rotate it until it correlates to the data). Make your life easier when first playing with it and make yourself some IR Led light sources. Don't expect a remote control to be a reliable source, you need a fixed light, not a data stream from an IR.

Can see four IR points and give coordinates, nowt up with that. What would save some fiddling is if they put on it which way was up.
