SISTec Major Project Report on Line Follower Robot

This project is developed for the users to use a digital calendar and temperature indicator. Anembedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today.
The main parts of this project are key pad, microcontroller unit and LCD display. In normal operation mode, the LCD display displays the Current time, date and day like an ordinary calendar. Also indicatethe updatedtemperature. The user can set the time, date and day using the key pad. When the user sets the timings, the settings will be displayed in the LCD display. The settings are stored in the microcontroller memory.
The most commonly used set of microcontrollers belong to 8051 Family. 8051 Microcontrollers continue to remain a preferred choice for a vast community of hobbyists and professionals. We used AT89S52 microcontroller of 8051 series and LM35 IC for temperature indicator.
When the function key is turned on, the microcontroller sends data to the LCD display to display the current time, date and day. If necessary, the user can modify the settings using the key pad. This project is very cheap and compact. Since microcontroller is used, the operations will be very accurate. The microcontroller program is written in embedded c.
