Traffic lights design based on 51 single-chip micr
no vote
Based on Keil c, and joint development of the Proteus platform to achieve a two-way design and simulation system of traffic lights at the crossroads, in the system, the microcontroller is used to simulate an intersection traffic lights running, represented by red, green, yellow LED lights, 4 groups (North, East), with digital display timer. First of all, turning on the lights, the North-South crossing the green light, 25s timing at the same time, 5s timer after the end, North-South crossing the green light flashing, timings and then when 2s North-South crossing the yellow light. 30s timer after the North-South crossing the lights, turning on the lights, and countdown to the 30s, one cycle.
