outside procedure inside the electric circuit, slice to cut over a control and shows

electric circuit. Take single slice the machine IntelAT89 C51 of the serieses MSC-51s

as a center spare part to design transportation light controller, carried out the AT89

C51's P's 0 people's constitution of the chips red, the function in bright time of green

light, Huang2 Deng Ran2;For the sake of system stability the credibility adopted a 74

LS14 airtight trigger eliminate of machine chip to tremble electric circuit especially,

avoided system because of importation the signal tremble movable property to living

a mistake operation; The P 2 people who shows that time directly passes the AT89

C51 output, is driven LED figures a tube by the CD4511 to show red-light Ran bright

time.
