【Abstract】 For the LED Dot matrix which is measured and graded,the key to the question is that the measurement and the resisted disturbance of the faint cold light are solved,we apply an intelligent device is devoted,which used to grade the LED Dot matrix according to its brightness.Based on MCS 51 series single chip microcomputer,and from the total plan to the hardware and software design of the where device,lots of analyses,proof and experiments are further carried out,so the described found a mental problem is well solved.更多还原
