WuKong is back to the huaGuo mountain, weapons and fighting monster around but fell lack of pil, and then he goes to the dragon palace for treasure. The dragon king is in the east China sea dragon, in charge of the rain clouds. At the button of the sea there is a Jane iron, weight 6750 Kg, can change the size with the thought, named  great treasure rod.[/vc_column_text][vc_tour][vc_tab title=”Project introduce ” tab_id=”1422102943-1-2″][vc_column_text]The WuKong  great treasure rod is amazing which can be big and small. Now we will use the pcduino Rotary Potentiometer can achieve this function, switch the button and try yourself.[/vc_column_text][/vc_tab][vc_tab title=”Hardware prepare” tab_id=”1422102943-2-41″][vc_column_text]1.Pcduino V3

Potentiometer is by changing the membrane resistance and the resistance rate to achieve the output voltage change, in this process, the terminal voltage and the resistance will not change with the external position, and the general slide 4-3[/vc_column_text][/vc_tab][/vc_tour][/vc_column][/vc_row]
