| Abstract: | In this paper, the design of LED lattice clock uses 5 lattice to display the time in the 24-hour respectively, with a 74LS138 decoder to scan for column , and adding the 74LS245 chip as the driver for lattice screen, according to make a simu-lation with Proteus and finally make the circuit board. The experimental results show that the principle of the system is easy to understand,and the circuit is simple with good stability. |
