Information on the Design of Failure Complex Detection House

Lack of attention to the developers of housing complexes in the matter of light,causing less terawatnya this facility. Thus we sometimes see in a housing complexthere are some lighting that is not functioning or damaged. If there are no complaintsfrom the residents, will require a long time to fix it or may not be completelyrepaired.Given the problems above, required a lighting failure detection system that canmonitor all the existing lighting at a housing complex. In this case, the authors use the8255 Programmable Peripheral Interface as an interface (interface) as a lightcontroller that uses the Turbo C as software that provides information to the operatortentrang housing complex lighting conditions

Circuit Design House Door Controller Interface Using Programmableperipheral (Ppi)-based 8255 Personal Computer (Pc)

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 option

Application as a Stepper Motor Driving Force on the Ladder Walking

Series of "Application For Power Drive stepper motor Staircase Walk On" which iscontrolled by a PC this is one of the efficient use of PC applications that can manageother peripherals.In Combination the 8255 PPI is controlled by a PC was applied to describe anexample of computerization with particular reference to give a value. Addresses areunique on the PC, meaning that each one addresses only owned by a location

Design Tool Room Door Alarm on At89c51 Microcontroller

In general, this door design tool can be applied easily. Optocoupler sensor responsetowards the open door can be detected properly. So also with the performance of LEDand buzzer as a timely warning when the sensor was detected.Specifically, the program for running the door alarm was spelled out successfully,because the microcontroller program commands can be processed and properlyinstructed
