New TFMini IR sensor and all is working again. Not a very durable unit. Runs on 3.5v logic (which I was using). Using an Adafruit FX soundboard. I tried serial control but strange bug does not allow for serial control of track 00, and all tracks are shifted by one track registry (so 1 plays on 2, etc..) and I can only get a total of 6 tracks (mono and short play time). Also , serial control has limited functions (stop, play, pause) and not the easy control the button mode has such as loop, hold, etc...
Therefore, I have to use 8 3904 transistors from Teensy 3.2 pinouts to run the grounds on the FX sound board to get all my sounds working. More soldering, less code!
Anyway, the lidar housing is almost done, and fits right on as a rail attachment. a few minor kinks to work out in the final LIDAR code then all together for paint and pics....
