Liquid Crystal Display

A thin, flat electronic visual display that uses the light modulating properties of liquid crystals is known as a liquid crystal display. Direct light is not emitted by LCDs. Displaced cathode ray tube (CRT) displays of LCDs are used in most applications. Two sheets of polarizing material, are used in LCD displays, with a liquid crystal solution between them. The crystals align as a result of an electric current, so that light cannot pass through them. Each crystal, therefore, is like a shutter, either blocking the light or allowing light to pass through. Some of the technologies behind liquid crystal display are as follows Illumination-A cold cathode fluorescent lamp that is situated behind the LCD panel is used as an…

Staff boards will be in the staff-room to display events in schools, important messages, whereabouts of staff and playground duties rota etc. In individual classrooms you will find that the pupils work is displayed or they…

Digital voltmeter using 8051 microcontroller

Voltmeter using 8051 microcontroller. Automatic railway gate control 8051 microcontroller use  adminOctober – 4 – 20127 CommentsVoltmeter using 8051. A simple 0-5V voltmeter using 8051 is shown in this article. This digital voltmeter has a sensitivity of 200mV which is a bit low but this project is meant for demonstrating how an ADC and seven segment display can be interfaced to 8051 to obtain a digital readout of the input voltage. A 31/2 digit high end voltmeter will be added soon. ADC0804 is the ADC and AT89S51 is the controller used in this project. Before attempting this project, go through these projects Interfacing ADC to 8051 and Interfacing seven segment display to 8051 which will give you a good idea on the…

Bulletin Board with Wireless Digital Display

This project aims to create a wireless transmission of data to a bulletin board for announcements, advertisements and posting of any kinds of informative statements that will be useful for readers, employees and students. 2.1 Problem Statement Electronic bulletin board cannot update information time by time. Our system can provide ready-made templates so that time by time, we can change the appearance base on the activity to be posted. Especially the proponent’s device can provide a wireless transmission of data to bulletin board with different displays. To achieve the goal, the proponents will be addressing the following problems. 2.1.1 General Problem How to create a PC based Bulletin Board with Wireless Digital Display System? 2.1.2 Specific Problems 2.1.3.1 How to…

Case No.2 : Lois Quam

Speech emotion analysis refers to the use of various methods to analyze vocal behavior as a marker of affect (e.g., emotions, moods, and stress), focusing on the nonverbal aspects of speech. The basic assumption is that there is a set of objectively measurable voice parameters that reflect the affective state a person is currently experiencing (or expressing for strategic purposes in social interaction). This assumption appears reasonable given that most affective states involve physiological reactions (e.g., changes in the autonomic and somatic nervous systems), which in turn modify different aspects of the voice production process. For example, the sympathetic arousal associated with an anger state often produce changes in respiration and an increase in muscle tension, which influence the vibration…
