摘要：Scientific writing is about the design and analysis of automatic light controldevices using the interface that is connected to a computer system as thecontroller of the system that will be used to control objects such as lightingcontrol. Currently most of the hotels to turn off and turn on the lights are doneby manually via the switch. The author makes an automatic lamp with DB25connector interface for ease of die and turn on the lights first floor hotel roomuntil the third floor. In this study, the authors illustrated using a model createdand implemented using Borland Delphi program, especially for lighting in everycorridor. The author analyzes the performance of automated lighting equipment,illustrated and translated into 5 (five), block diagrams, among others: (a) Parallelport as input, (b) Program to activate the switch, (c) inhibitors, (d) Regulatory,(e) displayed light as output to a flame or turn off the LED. The circuit is madeusing a voltage of 5V and the source of the LED voltage of 2.5 V. This toolworks by using algorithms and data presentation tool trials. The author suggeststwo points better on the placement of each LED using a voltage floor of 4V,because if the voltage obtained from the LED is less than 2.5 V, the LED will bedim. This automatic lighting circuit from a computer is using a voltage ofapproximately 5V so that the mock making use of the LED can work optimall. key words: db25 performance, automatic lights control
