Abstract

Has made the design of light search car robot based PIC16F84 microcontroller that can be applicable in world industry to attract goods by following the intensity of light sources and to determine the point of sunlight that fit so that solar cells work optimally in change heat energy into electrical current. This robot can work with a light dependent resistor (LDR) sensor to alter the physical property of light into electrical signals, then sensor output voltage from the LDR compared to the comparator circuit so output generated there were only two conditions: high (1) or low (0), from comparator circuit and then into functioning PIC16F84 microcontroller to drive two servo motors and display the data to Liquid Cristal Display (LCD). If the mobile robot is illuminated with a flashlight, it will logic high (1) so that the second servo motor rotates towards the flashlight and display the article toward the light, otherwise if there is no light source or a flashlight, then only one servo motor that rotating searching the light and display the article looking for the light. From the results of this design is obtained that the light search car robot able to detect the light source flashlight with an intensity -10 to 121 candela with the ability to detect light to a maximum distance of 4 m.
