I am moving a project from breadboard and jumper cables. It light a bunch of LEDs with different sets running of many almost every pin. I need a few meters of cables. I will a resistor on each led. I have no idea what kinda cable/wire to use and googling cable gets me nowhere. What kinda wire do people use?

  • I don't quite understand your question, but would ribbon cable fit the bill?

  • Otherwise, describe what sort of cable you're looking for (presumably you have some sort of idea) and someone may know what it's called.

When choosing wire for your project the main consideration is the amount of current. Second would be the distance.

For LEDs the current is generally low (milliamps) so something like a 20 or 22 gauge wire would be fine. You should be able to get it at a local hobby electronics shop or Amazon of course.

FYI, Wire gauge numbering is such that the lower the number the thicker wire. Thus 20 is thicker than 22.

You may find this AWG (American Wire Gauge) table helpful: http://www.powerstream.com/Wire_Size.htm

  • With careful choice of wire thickness and length paying close attention to the resistance-per-meter it may be possible to do away with the LED resistors entirely and use the resistance of the wire instead.
