Project Description

Automation is the need of today. The ultimate aim of technology is to reduce the load of mankind. This project aims at developing a SOLAR TRACKING SYSTEM, which involves the automatic control of the switching of the devices connected to the microcontroller based on the LDR sensed by the LDR sensor. Various devices have been interfaced to the microcontroller using opto-isolators circuits and relays. If the light value is between a specified range, then a certain number of devices will be working at that time. This number can be decided by the programmer at the time of the programming. The output of the LDR sensor in analog, which is fed to the ADC before it is sent to the microcontroller. The rotation of stepper motor is constantly displayed on the LCD. This way it implements solar tracking and device switching.

    Embedded System using 8051 Microcontroller

    Embedded system is basically a combination of hardware with software. Embedded system basically is a computer system that is designed to pull off a few or one specific function, more often than not in real-time computing constraints. An embedded system is called an embedded system because it is embedded in or is a part of much complex and complete device that comprises hardware, moveable and mechanical parts. They are basically microcontroller to work with ‘applications as a resulted output. A microcontroller is a device with its own memory (RAM, ROM) and many more features added to it such as UART, Interupts and Timer etc, which make it superior to the microprocessors.

    Very Large Scale Integration (VLSI)

    This is a process of stemming or creating integrated circuits by combing several thousands of transistors together on a single chip. VLSI stands for very large scale integration which in short has a purpose of integrating several numbers of semiconductors on a single chip. There are various VLSI technologies used as 45nm, 65nm. They have been named so depending on the length of the gate used in the transistors. A microprocessor is also a VLSI device. Structured VLSI design is a modular methodology originated just with an aim of saving microchip area by minimizing the interconnection area.

    Embedded System using PIC microcontroller

    Embedded system is basically a combination of hardware with software. Embedded system basically is a computer system that is designed to pull off a few or one specific function, more often than not in real-time computing constraints. PIC family is advancement over 8051. PIC is faster than 8051 and the biggest difference is that PIC is a microcontroller whereas 8051 is a processor. Many types of electronic projects can be constructed easily with the PIC family of microprocessors, as clocks, very simple video games, robots, and many more. It is code efficient and based on RISC. The PIC is a very general purpose microcontroller with ADC, counter, Built in oscillator with selectable speeds Wide range of interfaces including SPI, USB, USART, A/D, programmable comparators, PWM
