Schemaplic Schemaplic is a software used in Designing and simulation of electrical diagrams It is used in the field of electrical systems(Electrotechnical, Electromechanical, Energetics) and also pneumatic systems. This software has diverse features of component libraries having all essential components included. It also gives the characteristics of Each component. Due to its flexibility, the properties of components can be modified and customized to suit your design. It also contains a picture mode which displays the picture of each selected component. This picture mode can be activated or deactivated. The simulations can be saved, printed, or exported. It displays Faulty connections warnings. It also has Application exercises which are included in exercise libraries. This is one of the best softwares used in simulating electrical diagrams. There is the free version and the paid version.

Traffic Light Control System Design Project Traffic lights, also known as traffic signals, traffic lamps, traffic semaphore, signal lights, stop lights and robots, and also known technically as traffic control signals are signaling devices positioned at road intersections, pedestrian crossings and other locations to control competing flows of traffic. The first manually operated gas lit traffic light was installed in 1868 in London, though it was short-lived due to explosion. The first safe, automatic electric traffic lights were installed in the United States starting in the late 1890s Traffic lights alternate the right of way accorded to road users by displaying lights of a standard colour (red, yellow, and green) following a universal colour code. In the typical sequence of colour phases: the green light allows traffic to proceed in the direction denoted, the yellow light provides warning that the signal will be changing from green to red.

What is relay? It is switch that provides the safety to an electrical circuits from the abnormal conditions. Relay has two parts which is NO ( normally open ) and NC ( normally close ).  NO means the circuit are normally open, In this conditions the electric supply does not passes through the circuit due to the open circuit conditions. This type of relays are use in mechanical devices like hoist and manipulator for controlling. NC means the circuit is normally close, In this conditions the electric current can flow through the circuit due to the circuit is close And this relay coil is use as On switches in mechanical devices like hoist and manipulators.

Interfacing LM35 temperature sensor with PIC microcontroller An LM35 temperature sensor senses the temperature and produces Analog signals which is fed to a microcontroller which interprets the result. The microcontroller used here contains an Analog to Digital Converter (ADC) which receives the signals from the LM35 and produces a corresponding digital signal and the value of the temperature displayed on an LCD. Application: Room temperature control Egg incubator Dryers e.g. cocoa dryers, Green agriculture, etc. Materials: An LM35 A PIC 16F877A Two relays 2 transistors BC549 2 protective diodes (fly-back diodes) A Fan A heater A 16x2 LCD Supply DC 5/12V, AC 230V Circuit diagram of LM35 temperature sensor interface with microcontroller The circuitry is shown below Operation Lets control the temperature such that if the temperature is less than 25 degree Celsius, the heater is put ON and the fan OFF. If the temperature is about 25 degree Celsius, the
