Description: AT89C2051 only then 15 IO mouths, must demonstrate that 8 nixietubes are a little strenuous, essential expansion, therefore looks for the 74HC595 string to transfer and the shift register, makes section obviously one to make the position to elect, only used three IO mouths to solve 8+8 demonstrations, if must many not fear again, but 2051 only then 2K storage space, also has limited the demonstration figure. DS1302 takes 3 IO, this kind of P1 has only used 6 IO, but also two are emptying, prepares to establish LED to induce the autoswitch and DS18B20, if the procedure size permission joins again infrared swings controls, does big some LED demonstration, is a model of practical electron clock.
