I want to see working video kindly tell me how i can get its video? Frank Donald March 18, at am. I have used IDE to code this program so dont get confused.

Later the traffic lights were developed in the year by an American Traffic Signal Company, which fixed green and red lights at corners of the th street and Euclid Avenue in Cleveland, Ohio. During this period traffic lights were controlled either by timing or by switching manually. Traffic lights are also named as stoplights, road traffic lamps, traffic signals, stop-and-go lights which are signaling devices placed at road crossings, everyday pedestrian crossings and other locations to control competing flows of traffic.

Traffic lights have been fixed allover the world in many cities. Traffic light control system uses a worldwide color code a specific color order to enable color recognition for those who are color blind.

Typically traffic lights consist of three types of colored lights such as red, orange and green. In a typical cycle, turning on of a green light allows traffic to continue in the way indicated. So far we have given the introduction about traffic signals, and therefore a control system is necessary to control these lights in a specific manner. This traffic light control system can be achieved by using a microcontroller to make simple and low-cost system.

Now connect the red from the controller to the upper left terminal on the large black terminal block so as to connect with the red wire of the red light. Connect the yellow wire from the controller to the second from the left upper terminal to connect with the yellow light wire.

Connect the green from the controller to the upper terminal of the green light. Lastly connect the white from the controller to the upper right terminal to connect with the three white wires from the lights. Before turning on the power check to make sure all connections are to the proper terminals and are tight.

Also make sure there is nothing touching the bottom of the controller circuit board that can cause a short circuit. Now, when the power is applied a small LED light located in the middle of the circuit board should start to blink, if running sequence one, the green light should turn on go thru the green yellow and red sequence.

Set the ON times for each light by turning the three trim pots located on the top right corner of the controller board. You are done. Close up and enjoy. Located above the transformer and to the left of the relays is the six pole dip switch used to enter the sequences to your controller. The illustration on the right is one example of forty five others shown in your instructions for setting up your controller. This illustration is sequence number one which is the standard US sequence and preset to US customers.

Bring your none functioning traffic light back to the glorious life it had when it hung over a busy street or on a corner post controlling thousands of cars and trucks day and night, year after year. Installing our basic SL volt traffic light controller will restore full sequence operation to your light.

Some of the other popular programs to choose from are alternating flashing RR crossings, and cross walk signals. This is the controller of choice in the US and around the world for reliability, versatility, design and service. The use of energy saving voltage reducing transformers for maximum power efficiency, low cost operation and cool operation, no wasted power in heat generated by other voltage reducing methods and helps in the protection against damage from line surges.

Yes they click, but allow the use of power saving LED lights as low as 4 watts with no glow in the OFF state which can be a problem with solid state switching. All sequences and wiring diagrams are illustrated in very easy to follow picture style instructions shipped with each unit including photos of mounting and wiring. Purchase with confidence with nearly 16, controllers sold so far worldwide.

Longer times of 3, 4, and 5 minutes available on request, state on order. Average life for incandescent to hours. Three circuit controller for non-flashing "don't walk", and four circuit for flashing Don't Walk.

There are seven sequences programed in for this unit, from full intersection, Grand Prix style staging tree and other multiple light and arrow sequences.

With the old style traffic lights getting harder to find, the LED traffic lights are becoming more prevalent. The good news is LED's draw very little current and have a life span of several years. The down side is, they are very bright, and in most cases to bright for inside use.

The design of these lights prevents using a dimmer control at the line input. To keep a uniform light output when in use, there is an internal control which keeps the light constant as the line voltage fluctuates up and down, so a normal hardware store dimmer will not work. Our dimmer is specifically designed for this application. Shipped complete with dimmer circuit board, dimming control, LED wire connections and termination for input power. Also included is a flash drive with complete instructions on the disassembly, installation and reassembly.

Dimmer package includes three dimmers, one for each light. Not available thru Ebay, must order direct. For any inquiries, questions or commendations, please call: or email.
