182 PIC107 Street light that glows showing the road ahead for ½ km only on
sensing vehicles or any movement (Using PIC Microcontroller): Light
Emitting Diode (LED) replaces HID lamps by engaging a programmable
microcontroller that controls intensity by pulse width modulation which
enables energy saving during late nights considering low traffic density.
The pulse width becomes very narrow on sensing no movement of
vehicles. As the vehicle forwards, the intensity goes on increasing for few
lights ahead and as it passes away the intensity goes on falling.
