AT89S51 Microcontroller based on Digital Clock


AT89S51 Microcontroller based on Digital Clock
Digital hours to create this not too tough. This series is not my original project, I trace the series of files and program from the internet, there is no chance the program listing. when I download the file to its hex-hour direct approach.
