Need help with powering a led

I am new to Arduino,and I have a 170 (points/holes) breadboard, which is small and white, I want to test an LED (small red LED) if it can get powered, and I can't figure out how to I make the breadboard with power using only male-to-female jumper wires...can somebody help me? If you can I would like a photo with a tutorial if you don't mind so I can understand better...


I attached a photo below to see more exactly what I want to do

First, you need a current limiting resistor in series with the LED. About 220 Ohms is good.

Without a current limiting resistor, the LED or Arduino can be damaged. (In reality, probably not, but it's a "bad design" and other "bad things" can potentially happen.)

In those breadboards each row of 5 holes is connected together. What you've shown, there is no connection between the wires and the LED.

How to use a breadboard

If the problem is the male to female wires, you can insert some short, solid wires (like a LED or resistor lead or better some header pins,) into the breadboard to provide places for the female ends of the jumpers.

yeah,i just showed the wires,yall to see the wires are f-to-m

and to understand better

Your topic does not indicate any problem with IDE 1.x and hence has been moved to a more suitable location on the forum.


I strongly suggest male-to-male cables. It makes life a lot easier.

If you don't have a couple of long-legged header pins around (beginners rarely do), then take a spare resistor and cut both wire ends off, use those to make your jumpers male-male, and away you go.
Or, connect one female end on a 220 ohm resistor, put the other end into the breadboard, connect one leg of the LED to the breadboard, and put the other female jumper on the other leg of the LED. Will work for the time necessary for learning.
Start by powering the LED by plugging your male jumper ends into 5V and GND, with the resistor and LED wired per above; once you have the LED working, move the jumper from GND, or the jumper from 5V, to one of the Digital pins, and learn to turn the LED on and off in code.

Forgetting the resistor in this phrase :smiley: You never know how literal OP might take this.

:frowning: dont really understand :sob:Dors anybody have a minu breadboard that can show me how can i do that?:frowning:

True enough. But It was in reference to the circuit I had already described, so I presumed intelligence and sequential thought. My bad!

Not right now, but if no one's chipped in by then, I'll cobble something when I get to the lab, probably an hour or so from now.

But if the power is an arduino board and i have only male to female wires?

See post #7 by @camsysca

@sterretje I edited post# 7 for clarity, since you've quoted it as reference material.
Thanks!
@9andreidevloper I can't be much more explicit than what we've already given you. "I don't understand" isn't enough clarity to help you understand something. Your lead issue I've addressed. What more is it?

Im at really beginning with arduino,and i dont have much materials,and i asked if u can show me with photos,how do i make a led light on a mini breadboard(170holes),and i only have male to female wires

And I described how to get past that. Good luck!

Learn to spell. The word is "you."

Many people have "shown you how" but you refuse to follow instructions. That is not a problem. Electricity, electronics and programming are not interesting to everyone. If you want to learn, follow instructions and enjoy what we enjoy. If you do not want to learn or follow any of this, there is the rest of the world for you to explore. Find what you like, and enjoy learning more about it.

Take two jumper wires and cut them in half.
Throw away the female ends.
Splice the two male ends together.
Now you have a male to male jumper

Back in the bad old days (The World Before Time) we didn't have these "dupont jumers" that people are so dependent on.
We used 22 gauge solid core wire for "everything".
