Can you convert a hd microsoft web cam to a tv with just the yellow and white wires please help single female and in need. Of a cam

I just did the connection but it not working, what could have been wrong

Thanks .... I was connecting two cables.... One: black, white, red, green. Other: Orange, blue, green, white...

I was just confused about how should I connect it. Your article helped...

PS. The comment MARK MANN post is right, as I am from China, BUT those info are for AC currents (he/she said that), NOT USB cables.

how do you hook up an antenna for Wi-Fi to your USB port the Wi-Fi only has two wires but it has two sets and those are the same

So, my roommate's cat chewed partly through the USB cable for my keyboard, so I had to cut off the damaged part of the wire, but am having trouble reconnecting the wires. There is a red wire, a black wire, a green wire, a white wire and a copper wire...

HELP...?

Hey, I have one usb cable with white, blue, orange, green and the other one is black, red, yellow, blue. So, how do join these 2. which cable to which? Please help. Thanks.

Hi, I'm trying to attach my phone charger to a battery made of pennies, and I got the battery to work (it made 6.5 volts), but I don't know how to attach it to the charger. The charger has four wires (red, green, black, and white), but I don't know how to attach them. Any ideas?

#Mark Mann: you make a few points of note but then make the same mistake you are trying to correct: China, as with any modern country does have standards for all these things but as far as I am aware, in their domestic market the standards are often honoured more in the breach than the observance.

The wire colours you have referred to, such as the green yellow for earth is actually required by a multitude of international standards to be reserved for the purposes of protective earth conductors. For the most part, there are no specific colours associated with an active or neutral for example in a permanent installation mains circuit. Any associations of colour to purpose in mains wiring is purely conventional rather than specified by a standard. Mains cables on the other hand are far too uniform to be accidental.

The whole world is converging (and has been for over 20 years) to world wide uniform standards which is why the USA is moving to 115/230 (and has been for a very long time) and here in Aus we are changing from 240 to 230 and parts of europe are changing from 220 to 230. Notice the 230 is the common theme. :-)

While American Wire Gauge is common place in many parts of the world and especially in certain industries (transformer manufacture for example) it is profoundly unpopular with engineers everywhere except perhaps the US. It is a totally useless wire specification for all but the wire manufacturers. Does it help you to know that a wire has the diameter of a wire drawn from 1oz of copper to 24ft in length? Or would you rather know the diameter or cross sectional area?

So I'm afraid where you say China likes yellow/green for earth, it is actually the vast bulk of the planet that demands yellow/green for earth and if you don't then that makes you the odd man out and it does not signify anything bad about China or any of Asia, Australasia, Europe, South America etc etc.

Your underspec'd wires are an artefact of the now crazy AWG standard which simply does not have proper near equivalents to many common wire sizes spec'd in mm2. That problem too has more to do with the US holding fast to AWG when the rest of the world went metric decades ago.

Sorry, but these are the facts about this, they are not evidence of a stupidity in the inhabitants of the rest of the planet.

Im hooking up a little solar panel witch only has 2 wires and i wont to hook up a phone charger to it but it has red hot black ground and the two data wires do i need to have the data wires hooked up to?

Can i use just the red for hot and the black for ground? I dont need the other two wire for data im trying to make a solar panel charger and the solar panel is only got two wires

I don't know a thing of this cable just that most red is possible and black is neg.i learned a lot

I cut the usb 4 wire cord one mine to wire up with a 2 wire.... now the 2 wire was white and green , I used the white and green on the 4 wire. Will this charge up my drone?

there is also a copper wire in my samsung data cable. what is the use of it... ?

Not working only red light work and my mouse has got damaged now.....................................................HELP

Thanks for the explanation. Most helpful

Please be careful with generalized comments as in the article, "Black has always been the ground wire in almost all electronic devices." Terms like "almost" are too subjective" and this is a technical article correct? Moreover, the statement is false! CHINA the worlds largest producer of consumer electronics uses BLANK and DARK BROWN for the POSITIVE (Non-Ground) side for AC Circuits. I understand USB is 5V DC typically around .5A with Smart Phones Fast Charging with as much as 2A, however never the less, CHINA is taking over, at least by the numbers, and they do NOT subscribe to our colors that were made popular by the American Automotive Industry. Incidentally CHINA likes BLUE for negative and YELLOW/GREEN for Earth Ground. CHINA also does not follow the AWG. In CHINA wires are ALWAYS "under specification" when an AWG is called out. They will commonly misstate raw materials particularly "copper" and "Oxygen Free Copper." Economically, FALSE STATEMENTS from CHINA "always" or let me say "Unequivocally" is in their Economic Favor (i.e. they benefit by the false statement in terms of universal value and exchange).

I am hardwiring a Garmin Dash Cam in my car. I want to use the normal Garmin micro USB connector since it has a 90 deg connector to the cam and looks better. I have a low profile mini fuse (5V) plugged into a non-used 12V keyed on fuse slot that is reduced to 5.4V where I want to splice in the Garmin USB cable. The problem is the line carrying 5V has 2 wires RED and BLACK (I presume are POS and NEG). The 2 wires to the USB plug are RED and GREEN ( I thought would be POS and NEG also). When I splice the BLACK to GREEN and RED to RED I get nothing at the USB plug andd the Dash Cam does NOT turn on. Any help would be appreciated!

USB doesnt connect to aux, without an active adaptor, at least not in the sense of transmitting audio directly, as AUX carries an analogue signal encoded completely different from USB's UART digital encoding.

So how do u make a USB to aux where does the green wire hook up to

I like the topic I need to learn more on USB cabling. I needed yo replace the usb socket / plug but failed because I needed to understand the color codes. Thanks. But I'm still having the same challenge.

Hi Mr Mark.

Hope you're doing well.

I have a small problem. Having read this post I thought you might help me.

I have a laptop table below which are fixed two 5-volt fans that receive power from the USB port in the laptop.

The problem is that the metallic piece of that USB cable that is inserted in the laptop is corroded. So I cut that corroded USB cable metallic piece and tried to attach another one. But I have failed in doing so when though I have connected the right type cords. i-e green with black and red with white and tried to test it with a battery as well. But that didn't work.

Please help

How to check positive and negative

Yes it is important to have positive and negative known wires ,but the ground is vital

I have a USB cable with pink light green and white. Very confused. Connecting to a new end with white red black and green?

I'm trying to connect a micro USB (female to female), in order to connect my bluetooth controller to my cellphone, because the bluetooth isn't working. Firstly, is this possible? My problem is, I have one female end with red, green, white and black wires. The other female end has red, green and white wires, but there is no black wire. But there are two exposes wires without a color coding. Do you have any idea as to which ones I should connect? Do the two uncolored wires matter? Thanks for the help.

Hey i wanted to know can i use normal wires if i'm making my own USB cable

thanks

i got a question. wiring a mouse from PS2 to USB. i manage to get power on butt he mouse doesn't receive data.

ps2 wires are Black, Green, Yellow, Red. The USb wires are Green, Blue, Orange and white.

the connections are Red-Blue, Black-orange, Green-Yellow, Green-white.

None of this is right.. Blue is usually ground, not data-, green is always data+ in any color scheme, and white is data-..

The correct scheme if you want to connect these 2 different colored wires together would be this:

Red or orange = 5 V

White or gold = Data−

Green = Data+

Black or blue = Ground

So in other words, orange to red, white to white, green to green and blue to black
