Disc-shaped displays are used to display analog clock. Cylindrical displays are capable of displaying digits and text. The rotating light emitting diode display can be disc shaped or cylindrical shaped. In this project we rotates a set of LEDs for displaying characters, numbers and symbols in a rotating manner, that is the reason to call the system as a propeller LED display. This “illusion” is based on inertia of human eye. Propeller display is a linear array of LEDs, rotating at high angular velocity to generate a circular screen.

In this system a set of 4 wires which are placed at different water levels can be used to sense the water levels. In this project water level of the overhead tank is indicated on a 16*2 LCD. The main principle used in this project is “water conducts electricity”. The motor is switched off automatically when container or overhead tank is full. This project monitors the water level of the tank and automatically switches on the pump motor when ever tank is empty. Water Level Controller using Microcontroller: Let us see a brief explanation about the above mentioned projects. For their purpose, we have listed here some of the best embedded systems projects ideas which are all very helpful to get an idea about what type of projects that they can choose in engineering level. This list includes many 8051 Microcontroller Projects, PIC Projects and AVR Microcontroller projects. Some of the examples of microcontroller based projects are water level controller using 8051, Propeller LED display, Automatic Railway Gate Controller with High Speed Alerting System, Metal detector robot, Biometric attendance system, etc. Many engineering students show lot of interest to do the projects based on embedded systems in their final year. We use these embedded systems in our real life for many devices and applications such as Calculators, microwave, television remote control, home security and neighborhood traffic control systems, etc. So, we often use these embedded systems in simple and complicated devices too. These embedded systems help to make the work more convenient and accurate. One of its most important characteristic is gives the output within the time constraints or you can say they are time bound systems. Basically embedded systems are task specific devices. RAILWAY TRACK CRACK DETECTION SYSTEM PROJECT REPORT PDF SOFTWAREIn embedded systems, software commonly known as firmware is hidden inside the same hardware rather than in some other hardware. Water Level Controller using Microcontroller:Īn embedded system is nothing but a computer system which is designed to perform many operations such as to access the data, process the data, store the data and also control the data in electronics based systems.
