A team is designing a system to automatically turn on lights when someone enters a room. Which vocabulary words from the list would most likely be involved in their solution, and why?
Rectangle and Arrow, because they show the start and end of a process
Microcontroller and Light-Emitting Diode (LED), because the microcontroller can process input and control the LED to turn on the light
Rhombus and Execute, because they both represent decisions
Input and Computer Scientist, because input is always needed
