The purpose of this study was to automatically track an Unmanned Aerial Vehicle (UAV), with an electronically steered antenna. To make it possible to track the UAV during flights, a 2.4 GHz transmitter was mounted on Continue reading
In order to accurately determine the growth of greenhouse crops, the system based on AVR Single Chip microcontroller and wireless sensor networks is developed, it transfers data through the wireless transceiver devices without setting up electric wiring, the system structure is Continue reading
India is world’s largest democracy. Fundamental right to vote or simply voting in elections forms the basis of Indian democracy. In India all earlier elections a voter used to cast his vote by using ballot paper. This is a long, time-consuming process and very much Continue reading
Direct current (DC) motor has already become an important drive configuration for many applications across a wide range of powers and speeds. The ease of control and excellent performance of the DC motors will ensure that the number of applications using them will Continue reading
This project shows how to replace a microcontroller unit (MCU) on a six legged robot,involving adapting hardware and developing software. The robot is based on the mechanics from Lynx motion’s Phoenix Hexapod Robot, which is a Continue reading
The line following robot, operates as the name specifies. It is programmed to follow a dark line on a white background and detect turns or deviations and modify the Continue reading
The present car alarm systems are still of no match to the well-equipped thieves. It is just a matter of seconds to break through the Continue reading
Permittivity is an important property of dielectric materials. By measuring the permittivity of a material, it is possible to obtain information about the material’s physical and chemical properties, which are of great importance to many applications.
In this study, a realtime control system for a frequency-response (FR) permittivity sensor was developed. The core of the hardware was Continue reading
The ECG circuitry unit on the wrist captures abnormal heart beat signal from the patient. The micro controller on the stick runs a heart attack algorithm. Warning is given out to the person about his heart condition. The Bluetooth emergency calling system calls for medical help at the moment of heart attack. This project aims to shorten the time between the moment of heart attack and the Continue reading
The following document details the research and evelopment of an Automatic Solar radiation tracker. Fossil fuels are a relatively short-term energy source; consequently, the uses of alternative sources such as solar energy are becoming more wide spread. To make solar energy more viable, the efficiency of solar array systems must be maximized. A feasible approach to maximizing the efficiency of solar array systems is sun tracking. Proposed in this report is a system that Continue reading
THE MENTIONED PROJECT IS BASED ON THE WORLD,S MOST POWERFUL INTEL CONTROLLER 8051. MOST OF THE SERVICES PROVIDED IN TODAYS WORLD ARE VOICE INTERACTIVE, YOU CALL UP YOUR BANK AND COMPUTRISED VOICE WILL SPEAK TO YOU,AND GUIDE YOU TO ENTER A PARTICULAR NUMBER FROM YOUR PHONE TO GET THE DESIRED SERVICE.THIS SERVICE IS ONLY Continue reading
The C8051F411 offers a versatile, small (5 x 5 mm), highly integrated, low-power solution for voice applications. The 12-bit ADC and DAC allow for reasonable quality sound at a 8 kHz sampling rate, and the hardware Accumulation and Burst Mode features of the ADC provide for further improvements with small processing tradeoffs. Continue reading
In this modern world people are forced to use electronic devices in their daily life. Nowaday’s electronic voting machines are used for election. So we introduced a cellular voting machine based on microcontroller.
In this system there are two units, a master unit and a voting unit. The voting unit can be placed anywhere and the master unit is placed in a control room. The voting unit contains a DTMF coyer, which generates a DTMF tone and is transmitted to the master unit through the FM transmitter. The master contains a FM receiver, DTMF decoder, Micro controller and Display units. The tone from the voting unit is received by the receiver and is decoded and specific functions are carried out by micro controller and then it is displayed.
Create a voice recorder using a PIC or a microcontroller and ADC. Use some conditioning circuits to condition the microphone output and feed it to the ADC. The converted values can be stored in some kind of memory. Samsung has some nice memory chips that can be easily interfaced. Most modern MP3 players use this kind of memory. Continue reading
In the modern digital age which belongs to the fast and competitive ones time became one of the expensive things to spend with. Everyone tries to minimize the amount of time they spend for every deal. So technologies are emerging to satisfy this desire of people. This project aims at the point of developing an electronic system which helps people to control any process or devices from a remote location using Continue reading
