Abstract

This paper tries to introduce something a tool designed to counter Number of people who aim to be able to monitor the number of people in a room and show it on a seven segment display. This instrument is equipped with an alarm. Alarm Buzzer be useful to know if anyone who came into the room. This instrument is based on AT89C51 microcontroller, in which programs written in Assembler programming language. The sensor used is the Light Sensor (LDR), display using two seven segment, and a Buzzer alarm. This instrument is designed to be able to count the number of people within range of 00 to 99 people.

Abstract

The design of the door controller series is a tool that serves to open and close the doorby automatically, without having moved by human power with the desired degrees (inmultiples of 7.2). This tool is very useful especially in the Jakarta metropolitan arealike this because it can minimize the occurrence of theft in the home or the usualdifficulties encountered daily in the open or close the door of the house.This tool uses a stepper motor controlled by the controlling circuit (stepper motordriver). With PPI 8255 as a controller that can be programmed, these devices can beconnected to personal computers or PC so that its operation becomes very easy justby pressing one button on the menu of available options

Abstract

USB Flash Drive is a type of NAND-type flash memory combined with a USB 1.1 or 2.0 and used as data storage devices smaller and lighter. Because of the sophistication that has made USB Flash Drive becoming increasingly popular as an alternative replacement disk that has been used to store data.Today USB Flash Drive measures less in length between 4-7 cm and a thickness of only 0.5 -1 cm. The user can put pocket pants or shirt. No wonder if now is a USB Flash Drive is not only popular among the IT course, Device this one was very, very popular until the elementary school level was already familiar with the USB Flash Drive as a storage medium.

Abstract

In writing that I make with the title "The Determinants of Distance Series Four Wheels For Vehicles Using an optocoupler-based Microcontroller AT89S51" is intended to reduce the numberof accidents, especially for four-wheeled vehicle that almost happen every day either street or highway within the highway. This happens because not all vehicles have a range of security system that functions as a determinant of the distance if the distance a vehicle warner they are too close to another vehicle. Equipment will be placed on the front bumper that will alert you if the distance is too close.
