have become an integral part of human’s day-to-day life. With
this motivation in the mind, this project aims at designing and
implementing, a running model of traffic light controller which
is controlled according to the density of vehicle on road. We
will use AT89s52 microcontroller and Infra red sensor for
performing all the computation and control related task. Crystal
Oscillator 12 Mhz. 12 V transformer. IR Tx-Rx Pair. 555 Timer .
Discrete components: Resistors, Capacitors . The most common
colors used in traffic lights are red, amber (yellow), and
green. Red typically means stop or high level of danger; amber
typically means caution; and green typically means proceed with
care. Usually, the red light contains some orange in its hue,
and the green light contains some blue, to provide some support
for people with red-green col
