Dip trace is a circuit designing software. After completion of the designing circuit I prepared the layout. Then soldering process was done.

After completion of the soldering process I tested the circuit. Still the desired output was not obtained and so troubleshooting was done. In the process of troubleshooting I found the circuit aptly soldered and connected and hence came to conclusion that there was error in programming section which was later rectified and the desired results were obtained.

The device is manufactured using Atmels high-density nonvolatile memory technology and is compatible with the Industry-standard 80C51 instruction set and pin out. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory pro- grammar. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications.

In addition, the AT89S52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Power-down mode saves the RAM con- tents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset. Power range: 4V 5. Series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter.

The demodulated output signal can directly be decoded by a microprocessor. Features: Photo detector and preamplifier in one package Internal filter for PCM frequency Improved shielding against electrical field disturbance TTL and CMOS compatibility Output active low Low power consumption High immunity against ambient light Continuous data transmission possible up to bps Suitable burst length.

Automatic Room Light Controller With Bidirectional Visitor Counter

Introduction Of Project 1. The objective of this project is to make a controller based model to count number of persons visiting particular room and accordingly light up the room. Here we can use sensor and can know present number of persons. Also if at all one wants to know the number of people present in room so as not to have congestion. This circuit proves to be helpful.
