Consists of 5 rotating cuboids aka panels. Each of the four faces of the panels has a different ad. Depending on which face of the panels is infront we see a different ad. The face in front is controlled by motors. Sensors will be used to decide which ad to be displayed. For eg if the temperature sensor gives a high reading then the ice cream ad may be displayed. If the moisture sensor gives a high reading then an umbrella ad might be displayed. Bluetooth is used to control which levels decide which ads.
Parts needed are: Arduino Bluetooth module Temperature sensor Moisture sensor Small motors
