. This diagram shows how electricity flows through the circuit using yellow arrows.. This is called a closed circuit or a complete path for electricity to flow.. Remember that on each separate half of the breadboard, the holes in row 5 are electrically connected to each other.. This means, for example, that I can take the leads of the LED and move them to different holes in row 5, and it will still light up.. However, if I take the LED and move it to a different row entirely like row 4 or row 6, it does not light up, because there is no path for the electricity to flow.. It has to be in row 5 to have that complete path.. You can also reconfigure the entire circuit., For example. Here I am going to move the LED and the resistor over to the right side of the breadboard and then connect the battery pack’s negative lead to the ground bus on this side.. While this looks different electrically, it is the same circuit, so the LED still lights. Up.. You can see that in this diagram by tracing the yellow, arrows and noticing that there is still a closed path for the electricity to flow through the LED.. Now, let’s take a look at some of the most common mistakes that students make when learning to use a breadboard.. Here we have the demonstration circuit from the previous part of the video with a battery a resistor and an LED.

. This is because the leads aren’t pushed in all the way so to make sure it stays on. You have to make sure the LED is pushed firmly into the breadboard, along with the rest of the components.. The next common mistake will depend on the individual components in the project. You’Re doing.. Some components have polarity, meaning the direction they are facing. Matters. LEDs are a great and very common example. Notice. How if I grab the LED and flip it around it, doesn’t stay lit.. If you look closely at an LED you’ll see that the two legs are actually slightly different lengths.. The longer leg is the positive side and has to be connected to the battery pack’s red lead.. The shorter leg is the negative side and needs to be connected to the black lead.. The resistor, on the other hand, does not have a polarity associated with it. So I can flip the resistor around and the circuit will still work just fine. When using a breadboard you’ll have to decide what type of jumper wires you want to use and there are several different types. Available. First are these long, flexible, wires that come in many different colors and are usually sold in packs of at least 10.. The wires themselves are very flexible, but they have metal pins attached to their ends that make them easy to press into the breadboard.. While these wires can be very convenient for simple circuits, they can get very messy for complicated circuits and, as you add, more and more to a breadboard, you’ll eventually get a tangled nest of wires.

. This works great because now the pins on each side of the chip are each connected to their own row.. What you don’t want to do is put the entire chip just on one side of the breadboard, so it’s not straddling the gap.. Remember that the pins in each row on either side of the breadboard are electrically connected to each other. So if you put a chip in like this, you are shorting out the two pins in each row., Integrated circuits come in many different sizes and they all serve a special purpose. However, all of them will fit directly into a breadboard straddling this middle gap..

Awesome thanks!!

this is trash

5:32 Bullshit; Electricity flows from the negative to the positive terminal since electrons in our half of the universe are negativity charged. It’s basic circuit knowledge and that picture is misleading.

shut up man, jesus

2. Science Buddies says:

Copying our reply to someone else who posted a similar comment: the arrows in this case indicate the flow of “conventional current,” which is defined as the direction of positive current flow. As you pointed out, in a metal conductor, this is opposite the actual direction of electron flow. However, in general there are cases when the charge carriers can be protons or positive ions (e.g. a particle accelerator, a chemical reaction). I think which convention you use largely depends on what textbook you learned from or what classes you took. In my case, the physics and electrical engineering classes I took all used conventional current, not electron flow. You can read more about it here: https://www.mi.mun.ca/users/cchaulk/eltk1100/ivse/ivse.htm

3. roland van der Vegt says:

You might want to tone it down a bit when you lack knowledge of a particular subject. Drawing the current flow in the manner as shown in the video is according to the convention.

Your use of the word “bullshit” is rude and indicates that you question this man’s credibility which is preposterous…

4. vedic varma says:

@roland van der Vegt agreed @Badr Yasuo is misleading and saying a bunch of bullshit

5. ... says:

Lol u got owned kid.

6. Valentin Ojeda Villegas says:

Thanks for the vid!

7. Sartaj Jamal Chowdhury says:

Amazing tutorial! Thanks!

8. Xavnaruto M says:

u r very quiet today

9. Brandon Hatton says:

Dude!!! I cannot believe what I was doing wrong was so easy to fix the whole time! Thank you so much! Now I know better.

1. Science Buddies says:

We’re glad the video helped, Brandon!

10. Liamwantsfood says:

I know how to use these but im just bored

11. Ze Push says:

Not the kind of bread i was looking for , but i am intrigued.

12. Kiyeme Dy says:

Thank youu. I want deeper lessons

13. Charmine Taganile says:

Thank u..

14. Hassan Agha says:

Thanks for the video and sharing your knowledge. I am beginner and your videos are very useful for me.
Any information about the mini board robot shown at 0:28 ~ 0:33 ?

15. Kris says:

I’m not sure how I got here but this video was really insightful and easy to understand! Thanks for the knowledge.

16. BLAIR M Schirmer says:

@Science Buddies. Strange. wrt 6:25 I had always learned that within a circuit you put the resistor in front of the LED in order to keep the LED from burning out; yet here you have the resistor placed AFTER the LED, where it doesn’t seem to serve any real purpose. Can you explain? Thanks in advance.

1. Science Buddies says:

We get this question so often that we made another video just to explain it! The resistor can go before or after the LED, watch this video for the full explanation: https://youtu.be/NUKD9qESO58

17. Arneé Campos says:

Finally I understand how to built a circuit!! I’m on Electricity B class . I was struggling on understand about this. Thank you!!!

18. retepttebroc says:

Just the job for an old man. THANK YOU

19. Nick Chambers says:

As tutorial videos go, this is among the highest tier. Thank you
