Embedded Control System of DC Motor Using Microcontroller Arduino and PID Algorithm

The development of technology has a positive effect on the trade sector, creating smartphones that can be utilized in all activities combined with internet network. Activity is currently growing mobile trader city Pekanbaru. This caused much competition, for example, Pekanbaru area, especially Sialangmunggu village. Traders around difficult to find consumers because do not have precise location and time information. Therefore, researchers aim design build applications by utilizing functions google maps GPS (Global Positioning System) where Algorithm applied A* algorithm whose function nearest between buyers merchants, accommodate data from merchants know position traveling merchant. Process analysis will divided into running discusses workings process traders field. Then proposed system made author maximize current analysis. By making design, needs needed creation system. result using method displaying merchant's route user, provide fastest get trader. use also done closest user's location, display
