Answer Key: EV3 - UNDER CONSTRUCTION Move until Color_Unit Level
Answer Key: Unit Quiz
- A threshold is a cut-off value that divides a range of numbers into two groups: those above the threshold and those below.
- Since the threshold is 17 ((26+8)/2 = 17), the current reading of 16 is below the threshold and will be interpreted as dark.
- Since the Wait-for-Color Block is waiting for bright (>50), then the floor must be dark. Since the line is 10 above the threshold, then the dark floor must be 10 below the threshold, or 40. (Alternatively, 50 x 2 = 100; 100 – 60 = 40, so the threshold must be 40).
- Raise the volume to 100% and set the Finish parameter to 'Wait for Completion'.
