这是一个简的电子屏幕，用于小型车间，能显示年，月，日。计划产量，实际产量都可以显示在板上。我用protus实现硬件仿真，并最终有实际成品出来。-This is a simple electronic screen for the small workshop, to show the year, month, day. Program output, actual output can be displayed on the board. I realize protus hardware simulation, and ultimately have the actual finished product out.
