ABSTRACT

This project deals with the design and construction of an automatic traffic light controller. It uses complimentary metal oxide silicon (CMOS) integrated circuit(IC) (4017) as IC counters which sequences the light emitting diode. 555 timers are used to achieve the a stable multivibrator which drives the circuit. The power supply of this automatic traffic light was achieved using 240 V/12V step-down transformer, bridge rectifier and a positive 9V voltage regulator IC (7809) Electronics work bench (student circuit maker was used for the design and simulation of the work.
