Interconnection creates linkages of data amongsystems and people. High degrees of interconnectivity enable smart systems to become reality. The linkage and integration among people, objects, and systems are enabling new ways to gather, share, and act on information. Intelligence in the form of new computing models, algorithms, and advanced analytics will enable better decisions and outcomes for business, government, non-profits, and individual users, as well as reactions of complex systems to emergent demands. The brain behind these intelligent devices are microcontrollers. These little chips with the integration of other peripheral devices such as ram serial ports and others analyse input data and decide on which action will be most suitable in a given situation to some extent. The actuality of this project is to ensure that damages to sensitive parts of a laptop are prevented and to preserve the efficiency of the laptop by automatically cooling the laptop when it reaches it’s thresh hold temperature. So it was decided to create a prototype basic smart system that cools down overheating laptops.

АКТУАЛЬНІ ПИТАННЯ" 162  The aim of this project is to liberate an individual from experiencing error complications pertaining to heat while using his or her laptop. The prototype is a 34Ч24.5Ч4 cmmeasured as length width and height respectively. The main devices embedded in this prototype are an Arduino microcontroller, two2 watt fans running at a 12 v DC with a rotation speed of 3000 rpm, a 16 2 LCD display and a circuit board with basic elements such as resistors, capacitors, transistors and others.   Fig. 2 Electric circuit scheme of the prototype The schematic above shows how the electrical part of the prototype was designed. 12 volt 1 amp adapter was used to power the entire system. Current at 12volts is first transferred to the thermal fans through a 430-ohm resistor and a transistor before it’s connected to a digital pin. Then,a LM317 voltage regulator steps down the voltage from 12 to 5v this is then used to supply current to the Arduino microcontroller and the LCD display through a potentiometer.  Arduino microcontroller is fed with programmable instructions in sets of code using the Arduino IDE and C++ programming language. The temperature sensor DS18B20 collects temperature data from the heat vents of the laptop and then it’s sent to the microprocessor for analysis every 50 milliseconds. The thresh hold temperature to trip the fans is 40ºC so at any moment the temperature sensor detects this condition, the fans begin to rotate at maximum speed this occurs for until the temperature in the laptop decreases to 20ºC then the fans shut down and the process starts again. An electrical scheme for the project was developed by a fritzing software Program for the project was written using C++ on Arduino IDE  This is a basic description of how our smart systemworks although more features are yet to be added such as speed variation of the fans and an interrupt in the system for manual use. What we have displayed in this thesis is one of the few upcoming smart system prototypes by many electronic hobbyists. This shows enough proof that the in the next 20 to 30 years about 70 to 80 % of the world’s population will be integrated with smart systems.
