The vehicle tracking systems are designed for tracking the movement of a vehicle from a location at any time. Such system is equipped with a GPS receiver which maintains the GPS location of the device. The GPS location of the device traced by the GPS sensor is sent to a cloud server or cloud service with the help of a controller. This project is a simple implementation of such system on one of the most popular prototyping boards - Arduino UNO.
The first thing that erupts in mind is how many? Yes, there are many in fact plenty to fulfill considerable part of global energy demands. But we will only be discussing the most important ones here. Since renewable energy is no longer a niche technology, almost all small and big nations around the world have embarked on a race to impress the world with most spectacular solar energy projects of all types and let everyone know about their true potential.
In a previous tutorial - Arithmetic Circuits, digital circuits for performing arithmetic operations were designed. Like Arithmetic operations, comparison of numbers is also an important mathematical operation. From computing perspective, the comparison of numbers plays vital role in decision making and logical operations. In digital systems, the numbers are in the form of binary numbers. The comparison of two numbers determines whether one number is greater than, equal, or less than the other number. 
In digital systems, any information is represented by binary codes. There are many binary code systems as mentioned in the first tutorial of this series. A binary code of n bits can represent 2n discrete symbols or elements of coded information. The digital circuits that perform encoding of digital information are called encoders while digital circuits that decode the coded digital information are called decoders. An encoder with enable pins is called multiplexer while a decoder with enable pins is called demultiplexer. 
In the previous tutorial - More Combinational Circuits, the basic concepts of encoder, decoder, multiplexer and demultiplexer were discussed. An encoder is used to code digital information according to a pre-defined code system (like BCD, Gray, etc). An encoder inputs data (like from a keypad or keyboard) representing familiar numbers or characters or symbols and output coded binary numbers. So, it inputs the alphabetic characters and decimal numbers from an input device via individual wire lines and produces the outputs as binary coded representation of the input symbols. 
Are Electric Vehicles really the future of the automotive industry? Some battery-powered cars are already running quite successfully on the roads, breaking the prejudices and presumptions about the electric vehicles that were voiced in the early years of 21st century. 
The present day automotive world is overwhelmed with adoption of better convenience on a mass level. The range of these new luxury features range from Advanced Driver Assistance Systems (ADAS) to infotainment systems and other similar things. Needless to say, these have pulled up the overall travel experience to a complete new level. But these new systems have also increased our vulnerability. Hackers can now more easily enter into our lives, our systems and exploit us to a great level. 
Wayne Allen, the Intel data storage pathfinding team leader, likes to describe his work in simplest words, “I make it so you can save endless selfies.” It is true that all our laptops and smartphones are getting slimmer and more efficient with every passing day, the data centers are evolving at a much slower pace than that. There are a few aspects that are moving ahead in leaps and bounds but most are slogging.
