this scratch project works with pico board, so pico board is the controller! when you press the button on your pico board the sprite will change color. when you slide the slider the sprite will go along with slider! (i think). and when you connect a device into nether of the A,B,C,D jacks the sprite will say "A sensor connected" for other stuff like sensor values press the "run dieignosics" button (make sure all sensors are activeated).
