The AT89S52 is a low-power, high-performance 8-bit CMOS microcontroller with 8Kbytes of programmable Flash memory in the system. The device is manufactured using Atmel's high-density non-volatile memory technology and is compatible with the industry standard set of instructions and pin out. The flash onchip allows to reprogram the memory program in the system or through a conventional non-volatile memory programmer. By combining a versatile 8-bit CPU with programmable Flash into the system on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller that provides a highly flexible and cost-effective solution for many embedded control applications. The AT89S52 offers the following standard features: 8K bytes of Flash, 256 bytes of RAM, 32 I / O lines, Watchdog timer, two data indicators, three 16-bit timers / counters, six six-level interrupt architecture Full duplex serial port, onchip oscillator and clock circuitry. In addition, the AT89S52 is designed with static logic to operate up to zero frequencies and supports two software selectable power saving modes. Idle mode stops the CPU while allowing RAM, timer / counters, serial port, and interrupt system to continue to run. The shutdown mode saves the contents of the RAM but freezes the oscillator, disabling all other chip functions until the next interruption or hardware restart. Other microcontrollers can perform critical performance functions, where they may need to act more like a digital signal processor (DSP), with higher clock speeds and power consumption.

OUR WORK Vehicles consist of LDR followed by and some other components, where LDR is used as sensor. LDR detects the light and changes its internal resistance according to the light falling on it, which mounts more on the PVC pipe placed on the car grill or in front of such a way that the light falls on the LDR. When the light falls on it decreasing resistance and causes the LDR output to be anolag, to make it into the digital op-amp then it is used 89s52 under which it energized the relay. The relay operates and the voltage through the headlights is reduced. The headlight requirement is very common during the night trip. The same headlight that helps the driver for a better view during the night trip is also responsible for many accidents that are being caused. The driver has control of the headlamp that can be switched from high beam (bright) to dipped beam (dim). The headlight has to be adjusted according to the light requirement by the driver. It is necessary to lower the beam of the headlights and lower the beam headlight to a cross beam. As the bucket unit is well connected to the vehicle's lighting system. While driving a car at night a problem as many drivers do not dip the head lamps of their vehicles at night as they approach. The various switching operation is used to submerge head light which can distract the concentration. -Automatic entire circuit using 89S52 microcontrolador Dipper.
Land Rover cell phone controlled using AT89S52 is basically done to operate robots by cell phone in order to simplify the control of robots. It focuses primarily to overcome the limited working range of controlled wireless robots that uses the RF circuit. Robot controlled by cell phone offers the advantages of a robust control and increases the working range as large as the coverage area of the service provider. There is no interference with other controllers and give up to twelve controls. It allows you to control the robot just by pressing your mobile key from anywhere as your cell phone functions as a remote control. Although, the cell phone controlled the robot's appearance and its capabilities vary greatly. Although all robots share the characteristic of a mechanical structure, furniture under some form of control.
