Microcontroller › PIC › street light that glows for 1/2km only on detecting vehicle movement
LED replaces HID lamps by engaging a programmable mc 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 passses away the intensity goes on falling or goes off as detecting.
Can u Post the circuit diagram $ program for pic 16F877a????
