Test solar tracker - dance following GANGNAM STYLE (강남스타일)

On 5th July, we tested our solar tracker, it worked normally and successfully. The two Lego motors orients toward the light to ensure the board is perpendicular to the light.

Firstly, we assembled the "Robot" as shown in Figure 1.

Power supply should provide power to Arduino board and power supply board. Arduino board is connected to the power supply board for sending information to Lego Motor. And power supply is used to drive Lego Motor. Furthermore, photo-resistor will give feedback which represents the strength of light to Arduino. The Arduino board will control the motion of Lego Motor according to the feedback. If the photo-resistor receives brighter light, its resistance will be less, and the board will turn to that direction. After testing, this solar tracker danced following GANGNAM STYLE as shown in following video1:
