White Light Emitting Diode (LED) replaces HID lamps in street lighting system to include dimming feature. A microcontroller of 8051 family is used to control the intensity by developing pulse width modulated signals that drives a MOSFET to switch the LEDs accordingly to achieve desired operation.

In the present system, mostly the lighting up of highways is done through High Intensity Discharge lamps (HID), whose energy consumption is high. Its intensity cannot be controlled according to the requirement so there is a need to switch on to an alt ....etc

automatic headlight dimmer using ldr

The circuit described here can be built and used in your vehicle for an automatic dipping and dimming operation of the headlamps, in response to the intense lights coming from an opposite vehicle headlamps.You must have come across this irritating situation while driving at night when you find the headlight lamp focus from an opposite vehicle falling straight in your eyes, making things difficult to assess, giving rise to a situation of a collision or some kind of possible accident.Incidentally, the driver ....etc

Description.
In this cool integrated circuit to your auto headlight system, you can ride in the high beam.The cool chain headed will assume the duty of passing lamp shining against when vehicles approach lights and high beams when they pass over.
The chart is based on the photo transistor (Q1) to measure the oncoming vehicles and transistor Q2 (BC177) to switch the relay to control headlight.When the light from the opposite vehicle falls on Q2, the collector current of Q1 a ....etc

Project is based on the vanet created using zigbee. Vehicles mostly drive at high beam during night time which is uncomfortable for the car coming from opposite lane to pass away. Therefore we have introduced a device in which rather than switching the headlight to low beam, it automatically turns to low beam. The working is as follows.
Two circuits are made. Every circuit consists of a zigbee, an 89c51 atmega microcontroller, Max 232 IC, relay circuit and timmer ic's for connection to the headlight, RS 232 serial port. The zigbee creates a ve ....etc

White light on light-emitting diodes (LED) as a substitute for HID lamps in street lighting system, to include the dimming function. 8051 microcontroller family is used to control the intensity, developing a pulse-width modulated signals that triggers the MOSFET for switching LEDs accordingly to achieve the desired operation.

In this system, mainly covering roads is carried out through the discharge lamps (HID), the energy of which consumption is high. Its intensity may not be managed in accordance with the requirement there is therefore a nee ....etc

Ever wondered about how exciting the use of an Arduino board can be in your daily life? We present to you a very basic and a wonderful experiment. We often adjust the display brightness of our mobile phones to suit to our need. Haven t you felt the same need for your bedside lamps or any other lighting at home? Here we are going to teach you how to make an Arduino lamp dimmer. Using this project, you can control the brightness of your table lamp according to your need. And start building one of the best arduino projects.

What are the stuff ....etc
