The course design is the use of Microcomputer Principle test chamber to simulate the light-emitting diode streetlights control. A chip from the 8255 population of diode switching data collection to simulate day and night, by the flip-flop through the 8259 chip to control the street lamp light out. When bad weather conditions during the day in case of rain, snow or fog, through the control can be part of street lamps lit, the weather conditions improved extinguished When night comes, all street lamps lit, if late at night to reduce traffic flow, the can put out some street lights to reduce power load, reduce energy consumption.
