Hi @jskinner Not sure if you are using VEXcode V5 Text or Blocks, but we do have a STEM Lab that discusses how to use the Vision Sensor with VEXcode V5 Blocks. You can find it here: https://education.vex.com/parent-wrapper.php?id=vision-sensor-v5
There is also an example project in both VEXcode V5 Blocks & text that features the Vision Sensor.
Hope this helps.
