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...
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.
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.
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.
@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
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.
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".
