The intersection traffic light has realized the four corners vehicle control, this curriculum designed has mainly realized through 8255, 8259, 74ls240, 74ls273, 75452 combination matching, realized the information transmission, the diode extinguished the control and the countdown interrupt brightly,

Vehicle control for the intersection traffic lights at the crossroads, the course design is mainly achieved through 8,255,, 74ls240, 74ls273, 75,452 combination match, realizing information transfer, diode lights out control, and countdown timer interrupt, eventually LED tube changes once per second

Crossroad traffic lights to achieve the intersection vehicle control, this curriculum design achieved through, 8,255, 74ls240, 74ls273, 75,452 mix and match, realizing information transfer, diode light countdown to fight control and interrupt, eventually LED tube changes once per second, ability to
