project‚ our aim is to use PIC or 8051 microcontroller to control a row of LEDs to function it as a clock. ABSTRACT :- The Propeller Clock is an electronic device which has a series of LEDs on board that rotate with the help of a motor to give an illusion of a watching a clock ( Digital or Analogue ). This requires a DC motor which rotates the PCB connected to it with sufficient speed so as to create the illusion. The LEDs are connected to a microcontroller PIC16C84 or 16F84 which is so programmed

terminal voltage regulator is used for voltage regulation. The programming language used for developing the software to the microcontroller is Embedded/Assembly. The AVR STUDIO is used to edit‚ compile and debug this program. SINAPROG programmer is used for burning the developed code on AVR STUDIO in to the microcontroller Chip. Here in our application we are using AVR microcontroller which is Flash Programmable IC.

METHOD: In this concept two mobile phones with different service numbers are used‚ the control phone at receiving end‚ where the appliances are controlled is interfaced with microcontroller unit which controls the devices through relays. To achieve this‚ the output of the mobile is amplified and fed to DTMF decoder chip‚ which generates binary code according to the received information from the other mobile phone. After establishing

signals of human beings buried under earthquake rubble. By proper processing of these signals‚ the status of the person under trap can be easily judged. The entire process takes place within a few seconds as the system is controlled by a PIC Microcontroller unit. 1. Introduction At present as we know the need of an hour is to find an effective method for rescuing people buried under the earthquake rubble or collapsed building. It has to be done before we experience another quake

they can’t. So keeping in this mind we are designing a new display system which can access remotely‚ we are using the GSM technology to access the display’s is one of the new technology in the embedded field to make the communication between microcontroller and mobile. This project is a remote notice board with MODEM connected to it‚ so if the user wants to display some messages‚ he will send the messages in SMS format the MODEM in the display system will receive the message and update

behavior of the system is based on sensor. Based on sensing information the microcontroller will respond. This system works on 5V power supply. Here Microcontroller plays a major role which takes inputs from sensor‚ process the information and give outputs to LCD. There is only one sensor i.e‚ Temperature sensor is embedded in the system thereby the microcontroller will respond to input sensors information. Microcontroller works only digital data‚ but temperature sensor gives analog data‚ so we need

Definition of a Microcontroller Microcontroller‚ as the name suggests‚ are small controllers. They are like single chip computersthat are often embedded into other systems to function as processing/controlling unit. For example‚ the remote control you are using probably has microcontrollers inside that do decodingand other controlling functions. They are also used in automobiles‚ washing machines‚microwave ovens‚ toys ... etc‚ where automation is needed.The key features of microcontrollers include: ➢
