Direct Traffic with Gloves

LED glove to direct traffic

Problem

Safety in the roads is a big concern for both pedestrians and drivers, in both developed and third world countries.

Pedestrians crossing the street in the dark. If they do not wear bright clothing or reflective clothing,there can be accidents. They can wear the glove with a white light in order to be seen by the drivers.

When a traffic light fails, police officers need to direct the traffic on their own. And they often put themselves in danger because cars may not be able to see them very well. However, if they use the glove, not only will they be see, they will also be able to direct the traffic much better.

 

 

Method

I designed a glove that could be used to direct traffic and increase safety and therefore decrease pedestrian accidents. This glove is more cost effective and could be a great solution for third world countries like India and Bhutan, where they don't have many traffic lights.

I soldered 5 LEDS together of each colour. On the LED, there is a negative terminal and a positive terminal. I connected a green wire to the negative terminal, and a red wire to the positive terminal. I did that to both colours, and then attached them to the glove. I connected both sets of LEDs together with a green wire, by the negative terminal. After that, I soldered together the black wire from the battery pack to a negative terminal of one of the LEDs. I  connected the red wire on the battery pack to a piece of copper tape attached to the glove. I did the same for both sets of LEDs on separate fingers of the glove. When I touch together my index finger and my middle finger, the green LEDs light up. When I touch together my thumb and my index finger, the red LEDs light up. The reason for that is because the LEDs all have a common ground, but the positive wire of the battery pack is not connected to any of the LEDS. When I touch together the copper wires, which act as a switch, the positive terminal of the battery is connected to the LEDs.

Analysis

When I was soldering my wires, i should've soldered two wires at the same time in the LED in order that i wouldn’t need to resolder it. I had to unsolder it using a different soldering iron, which was much hotter than the one before. The wires got ruined though, so I had to cut some more wire, but I had the LEDs saved.

The first glove I got was a rubber gardening glove which was not able to hold the design. I was looking around the house for other gloves that would work until I found the correct one.

One of my LEDs stopped working, so I had to figure out what had happened. I looked closer, and I saw that one part of the wire was touching the LED itself, so I had to tuck it back in.

To expand on my project, I can do three colours instead of two, on the glove. I can also do the same design on a vest or other clothing. I can also try to make it waterproof.

 

Conclusion

In conclusion, my experiment worked well. I tested it out in the dark, and you are able to see it from far. I think that if it becomes something that is used in everyday life, it will benefit society a lot. The glove can help direct traffic, as well as help pedestrians cross the street in low light. I had some problems with creating the glove, but I was able to overcome them using my resources to help me. All in all, my experiment was a success.
