For this type of traffic light controller, a FAB intelligent micro controller unit is utilise to program the desired traffic light sequence that includes the ambulance safe pass sequence.The building blocks inside Johnson decennium counters, astable multi-vibrator timers and the FAB micro controller such as logic circuits, flip flops, Karnaugh maps, truth tables and Boolean expressions ar also presented in the Appendix section of the report.Traffic lights ar an essential part of modern life, particularly with the increasing number of vehicles that coincides with the increasing number of population. Traffic lights not only regulate traffic die hard in the streets but more importantly prevent the occurrence of vehicular accidents. Roads without traffic lights are unimaginable. The traffic light controller is a sequential device that needs to be designed and programmed finished with(predicate) multiple step procedures. A proper traffic light requires accurate timing, correct cycling through the states, and responds to outs ide outputs such as walk signals or ambulance safe passage.The objective of this report is to design and employ traffic light controllers for a simple North/ South and East/ West road crossing as shown in figure below.
