Photo Diodes to Detect Laser Reflections

this was my senior design project, using cheap 650nm lasers and photo resistors. Had to use an analog to digital converter to get the photo resistors to register with the FPGA but I got it to recognize the block of the laser.

That's really a neat science project, Kendall. Once we get our feet wet playing with the lasers and photodiodes, I may have some questions for you or ask for project suggestions. I have some photo resistors and I will play with them tomorrow (after I shovel snow).

Thanks,
