Here we have explained a dark detector circuit by using 555 timer IC and a LDR (Light Dependent Resistor) which senses the light in surroundings and if it does not find the light, it triggers the IC and glows an LED attached with the circuit. In place of LED we can also use a buzzer or speaker to use it as dark detector alarm. The concept of this circuit is quite simple and based on the working of LDR. So lets first understand more about LDRs.
LDRs are a type resistors made from semiconductor materials to enable them to have their light sensit ....etc

System Interfaced with Mobile (SIM) is the concept of using Wi-Fi to control the activities of the computer system. Now the most common usage of giving input to the system is through a optical mouse and a QWERTY keyboard. Though these have been used for many years for now, it has resulted in repetitive stress injuries to fingers along with restriction of blood circulation due to the same posture for many hours. here introducing a concept to reduce these problems as much as possible through the use of mobile phones. The suggested method for mini ....etc

arm 7 based CAN for accident avoidance in automobiles circuit diagram & flowchart

Based on requirements of modern vehicle, in-vehicle Controller Area Network (CAN) architecture has been implemented. In order to reduce point to point wiring harness in vehicle automation, CAN is suggested as a means for data communication within the vehicle environment. The benefits of CAN bus based network over traditional point to point schemes will offer increased flexibility and expandability for future technology insertions. This paper describes system whic ....etc

A practical method of modeling wind generator control systems for network simulation using Matlab-Simulink is presented. The interface developed between PSS/E and Matlab-Simulink allows the models generated to be used directly in PSS/E dynamic simulation. Fundamentally, modeling involves understanding the dynamics of equipments to be modeled and deriving the differential and algebraic equations which are coded using a high level computing language. For network elements resilient to change, the latter remains the method.
However, wind generator ....etc

WSAZ uses its low-power translator in Charleston to provide viewers with a split newscast. Weeknights at 6 and 11, the two anchors appear together on screen until a certain point (usually 10-15 minutes into the newscast) when the show will split. For the last 20 minutes of the newscast, viewers in the 28 counties of the Kanawha Valley who watch channel 16 and Suddenlink will see a newscast targeted specifically to them while viewers in the other 33 counties (as well as satellite viewers) will see a newscast featuring coverage from Kentucky ....etc
