Development Of Microcontroller Based Identification Card Features Identifier

As automation is the next leading step in changing the traditional techniques, the means of making these changes possible is currently in trend. Automating the whole system not only reduces time, but it also saves a lot of resources and man-power. Just assume if a company has a worker employed only for counting the finished products and if this worker is replaced by a digital automatic system, then the chances of false counting, errors […]

Due to the advancement in science and technology all over the world, there is a significant increase in the rate of crime and sophistication in crimes; as a result, it is necessary to ensure the security of one’s self and one’s valuable belongings. The main goal of this paper is aimed at creating an electronic security system capable of detecting an intruder and reporting to security personnel. The design of the microcontroller based e […]

LPG gas is commonly used in our home for cooking purpose. LPG is used in school and college canteens; also it is used in various industries. Accidents never happen with a prior intimation. There are chances of gas leakage due to some negligence or as a result of faulty cylinder. In such cases, if leakage is not detected at an early stage, then it can create huge damages. Arduino microcontroller based LPG gas leakage detector can be use […]

Monitoring of fuel going inside the tank during fuel filling process is a difficult task. With the help of this system fuel going inside the tank when the fuel is being filled can be monitored. This type of system can be used to measure the amount of petrol, diesel or some other type of liquid. The purpose of this device is to prevent fraud in petrol pumps where in some cases the quantity of fuel displayed in the filling machine is not […]

Now a day’s many school/college bells are manually operated. Hence there is a huge demand of accuracy. In market there are many digital clocks available with bells but rings only at specific time and cannot stop after specific time. Here a new and inexpensive design is being presented. The benefit of this design is that the bell rings at the start of each period without any human intervention to a great degree of accuracy and hence tak […]

Speed control of a machine is the most vital and important part in any industrial organization. This paper is designed to develop a four quadrant speed control system for a DC motor using microcontroller. The motor is operated in four quadrants i.e. clockwise, counter clock-wise, forward brake and reverse brake. It also has a feature of speed control. The four quadrant operation of the dc motor is best suited for industries where motor […]

T-junction traffic light controller is such a device that will play a significant role in controlling traffic at junctions, to ease the expected increased rush at such junctions and reduce to minimum disorderliness that may arise, as well as allowing the pedestrians a right of the way at intervals rather than being struck down when in a hurry to cross the roads. Such an electrical system with a touch of electronics that control the flo […]
