Arithmetic circuits
An arithmetic circuit is a set of gates with a separate set of inputs for each number that has to be processed. The gates are connected so as to carry out an arithmetic action and the outputs of the gate circuit are the digits of the result

Asynchronous counter
Asynchronous counters are those whose output is free from the clock signal. Because the flip flops in asynchronous counters are supplied with different clock signals, there may be delay in producing output. The required number of logic gates to design asynchronous counters is very less
Sequential circuits
digital circuit theory, sequential logic is a type of logic circuit whose output depends not only on the present value of its input signals but on the sequence of past inputs, the input history as well. This is in contrast to combinational logic, whose output is a function of only the present input.
Latches and flip flops
In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs
AUTOMATIC VEHICLE LOCATION
A GPS receiver placed in a car can receive signals from these satellites and will calculate the exact location of the car in terms of latitude and longitude. This data can be sent to owner’s computer that can monitor the location. A GSM modem can be integrated into this project for providing security and remote control. The current location of the car can be found out by sending an SMS. The car can also be disabled by sending an SMS.

PROGRAMMABLE LOGIC CONTROLLER (PLC)
Automation devices such as controllers and data systems and or services. Systems and methods are provided that receive statements or other unit of data interaction from an automation device, provide the statements to an appropriate system or service for processing, and optionally return a response such as a result set. Furthermore, in accordance with an aspect of the invention native controller code, variables, or tags can be mapped to stored data, procedures or combinations of data and/or procedures and updated automatically or semi automatically. A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or lighting fixtures. PLCs are used in many industries and machines. Unlike general-purpose The subject invention pertains to facilitating communication between industrial computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed or non-volatile memory. A PLC is an example of a real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result.
