Absolutely, went back after I left here, and rewatched some of the video's, at one point some one mentioned 50 ms sample times. I would have been thrilled with 1 sec.That's using the lidar type TOF. Lidar is reflective , and that worried me a little , wood not being a particularly reflective material, but from everything I checked out on LIDAR, it seems to reflect off of , and therefor read , just about anything. That leaves me just needing to learn how to make it work with Arduino to function the way I want. Of course all of this is still in theory and idea stage, and as I keep moving forward I keep finding more functions the Arduino will need to be able to control. I would like to eventually move it to a marketable piece so that means combining in safety features and self calibration features that will eat up a lot space in a program.
