To describe the performance or work of electronic schematic of Light Detector Robot as like in figure 1 above we can divide into three parts. In sensor, Microcontroller, and driver dc motor. In this part we use LDR as light detector or sensor. LDR will change the resistance when this component detect the light. With the circuit above LDR connected
Electronic Schematic Diagram of Light Detector Robot using Light Dependent Resistor (LDR) - schematic

with the resistor to make voltage divider as output sensor. This voltage will be input in IC LM355 or LM311 that will compared with reference voltage. This IC used to make digital voltage in output from this sensor that used to as input data to microcontrolller AT89S51. Microcontroller AT89S51 can used to controlled the input data from sensor part. We can program this IC using specific program like assembly or C programming to follow the logical how this robot will move when this robot detect the light from the sensor part. To program this IC you must have skill in microcontroller. You can use MIDE Programming Software and also ISP Programming to do it. This is the last part in this schematic. We can design dc motor driver using IC L293D to get 2 part DC motor driver. Data input this IC came from microcontroller and the output of this IC will be connected to DC motor that run the wheel of this robot. So you can try using the Electronic Schematic Diagram of Light Detector Robot using Light Dependent Resistor (LDR) to complete your project.
