Micro:bit Photogate


   

     Bob Bumgarner, a Physics teacher at King George High School, programmed a Micro:bit so that it could be used as a photogate, a device for very accurate timing.  He also designed a holder for the bit using Tinkercad, and 3D printed it.  Bob was generous enough to provide his description of the project, the Micro:bit code, and the .stl file for the holder.  This is a very practical use for both the micro:bit and 3D design/printing.  As Bob points out, it is a way to save a good bit of money on lab equipment.  To read Bob's report click here, the code is here, and the .stl file is here.
