Schematic diagram of clock circuit composed of AT89C2051

Posted on Feb 6, 2014

The circuit composition determines that the LED adopts anodic Nixie tube. It can use LQ5101BS general luminous diode and the driving triode can use 2SA1015 or 2SC1815 types which is easy to gain. Of cause, the triode can also use low-power triode such as S9012, S9013, S9014, 2N5401, and 2N5555 etc. There are no special requirements for other componen

ts. To make the experiment easier, monolithic AT89C2051 can use DIP20P socket. The program need no debugging after written, and it can be copied to AT89C2051. What worth mentioning is that AT89C2051 is a flash program memorizer, and the program can be rewritten repeatedly, which makes it very easy to conduct experiments.
