As the name suggests “Automatic Night Lamp with Morning Alarm” was developed using Microprocessor. 8085 is the Heart of the system. The sensors are made with help of LDR which are Light Dependent Resistors, whose Resistance is inversely proportional to the Light falling on it. The LDR converts the light energy into electrical energy and this variable electrical energy was converted into digital signal (0 or 1) by using the timer IC555. The Timer IC output goes low when light falls on the LDR and the timer IC output goes high when the LDR was placed in dark circuit is as shown in below figure: circuit the flow chart for Automatic Night Lamp with Morning Alarm using 8085 Microprocessor is as shown in following fig. flow chart the program for Automatic Night Lamp with Morning Alarm using 8085 Microprocessor this is as shown below make sure that the Power supply pins & Port number before you connect the Hardware to the Trainer Kit. 0001   0000 0002   0000 ...

AUTOMATIC NIGHT LAMP WITH MORNING ALARM USING MICROPROCESSOR INTRODUCTION: This Project "Automatic Night Lamp with Morning Alarm" was developed using Microprocessor. It is the Heart of the system. The sensors are made with help of LDR which are Light  Dependent  Resistors,  whose  Resistance  is  inversely proportional to the Light falling on it. The LDR converts the light energy into electrical energy and this variable electrical energy was converted into digital signal (0 or 1) by using the timer IC555. The Timer IC output goes low when light falls on the LDR and the timer IC output goes high when the LDR was placed in dark. OBJECTIVE: 1) Tolearn and develop knowledge in designing the application by using the microprocessor. 2) Tolearn how to write an assembly language and combining with the hardware. 3) Tolearn how make a full report of project Microprocessor Also check our small business blog startuphq.in SYSTEM DESCRIPTION: In  thi...

Remote-Controlled Home Automation System via Bluetooth Home Network Recently the idea of a home automation has been an important issue in many publications and home appliances companies. Home automation is a house or living environment that contains the technology to allow devices and systems to be controlled automatically. Remote and local control are useful to keep home comfortable and to support the elderly and the disabled people. In this paper, we discuss possible developments of Bluetooth wireless technologies and describe the hardware for devices and software for the considerations of a home automation system. Finally, we have validated the testbed by simulating in the Bluetooth home network. Introduction: Bluetooth technology is capable of transmitting data and voice at half-duplex rates of up to 1 Mbps without the use of cables between portable and fixed electronic devices. Home automation is one of the major applications of Bluetooth technology. The core tech...

Power Generation Using Speed Breaker with Auto Street Light In day today life, power is a major need for human life. There is a need to develop non-conventional sources for power generation due to the reason that our conventional sources of power are getting scarcer by the day. This paper emphasises on the idea that the kinetic energy getting wasted while vehicles move can be utilized to generate power by using a special arrangement called “power hump”. This generated power can be used for general purpose applications like streetlights, traffic signals. In addition, we could also have solar panels, which would satisfy our power needs, when there is no vehicular movement. Introduction: In the present day scenario power has become the major need for human life. Energy is an important input in all the sectors of any countries economy. The day-to-day increasing population and decreasing conventional sources for power generation, provides a need to think on non-conventional e...

Lemon Battery The lemon battery is a simple type of electrical battery that is commonly made for school science projects because it illustrates a battery's main components. Typically, a piece of zinc metal and a piece of copper metal are inserted into a lemon. Everyday objects such as galvanized nails and copper pennies can be used for the zinc and for the copper. A single lemon is usually studied using an electrical meter. Several lemons can be wired together to form a more powerful battery that will power a light-emitting diode, a buzzer, or a digital clock. The lemon battery is similar to the first electrical battery invented in 1800 by Alessandro Volta in Italy. Volta used brine (salt water) instead of lemon juice. The lemon battery is described in some textbooks in order to illustrate the chemical reactions that occur in batteries. The zinc and copper are called the electrodes of the battery, and the juice inside the lemon is called the electrolyte. There are many variat...
