Microcontroller Based Cellular Voting Machine
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. Continue reading
Microprocessor based railway system
The aim of this project is to demonstrate the incorporation of computer method in railway traffic control to improve, safety, speed of handling the traffic and also reliability. Here we employ the microprocessor (Intel 8085) to handle the signaling, track changing and Continue reading
Blood Pressure Monitor Block Diagram and Design Considerations
Design Considerations:
Blood pressure monitors can use Korotkoff, Oscillometry, or Pulse Transit Time methods to measure blood pressure. They employ a pressure cuff, pump, and transducer to measure the Continue reading
Embedded Internet for Pulse Oximeters
In recent years there has been many investigations into sleeping disorders. Many studies are carried out in specially equipped units in which a patient is monitored whilst sleeping. Measurements that are taken are in the form of Continue reading
Novel Application of Diffractive Optical Elements in Optical Systems
Dammann proposed the special type of diffraction grating which is periodic in nature together with binary phase for achieving a high splitting ratio. Later on, researchers proposed different kinds of methods for improving the performances. Dammann Gratings can be used in many areas, and in this project, we aim to Continue reading
Voice recorder using ADC and Microcontroller
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
