Get Started in Electronics #2 - How To Control LED Brightness with Resistors

[@lizk6007]

Thanks for these! I'm completely new to electronics, and I love how you explain things from the basics up. It's so helpful to read the instructions for the lesson, try to understand it as best as I can first, and then watch your video to fill in the gaps and get the context. Plus, the dad jokes make me smile! :) Thanks, and I look forward to progressing through the rest of the kit with your videos!

[@pewpew1645]

I just bought this starter kit and was struggling with the tutorials. This explains a lot more to me. Thanks :)

[@BV3D]

Glad I could help!

[@Sum_Wun]

After watching numerous videos about getting started w/ electronics this is the first that really made alot of the terms and concepts make sense. Great job explaining all this. I had seen alot of your videos when researching 3D printing topics in the past but was surprised to see you pop up on my screen when looking up electronics kits. Keep up the good work!

[@mikehallvideos]

I really needed a much more thorough explanation of how electricity flows through the bread board. This was so helpful!!

[@christopher958]

Ive just bought the Super starter kit and have been following your Get started series. You explain things so well and eloquently flow between things you are explaining and similar things in the project, really helpful and the pacing is just right! Thank you and keep up the good content!

[@stevegrande1698]

This was an excellent way to display the basics of the way an LED illuminates. I was also impressed with the way you explained polarity with the diode. You are exactly right in explaining that the current flows from negative to positive. Last, your explanation of the breadboard was great. Today, if you are going to build circuits you must understand the organization of the board and where to place the wires and also, as you mentioned, it is equally important to follow a standard wire coloring (i.e. Red + Black Power , Blue Control, Orange or yellow data).

[@astrolabium88]

Another great lesson! I love these . I was lost when I first opened this kit but you are really helping me find my way . Thank you

[@BV3D]

There's another one coming out in a couple of days! 😀

[@johnfoster3895]

FINALLY - someone that teaches ELECTRON FLOW correctly and not the 'cornfusing' Hole Flow. Holes do nothing. Electrons do the work. I have taught electronics since 1984, either in the Navy or at college level. I've had many students that had attended classes that taught hole flow. A very good lesson! ET1(SW) MTS US NAVY (RET)

[@esh6767]

Really appreciate these lessons. I'm a computer science major looking to mess around with electronics, and this sure does help!

[@mason-rl3331]

I just got the Complete Starter set for Christmas and these videos have been so helpful with getting started. Keep making them!!!

[@BV3D]

Thanks, Mason!

how u doing with it

[@mason-rl3331]

Kley - Nice man! I love how much stuff is in there and am super excited to use it all, the only problem is I’m by no means an experienced programmer in Java so writing code can be difficult. But hey, that’s why I got the set, hope to improve. How about you?

[@KyleHA]

@@mason-rl3331 I'm doing pretty good with it too I like putting it all together and seeing if it works and trying to fix it if it doesn't and I got it to learn how to code hopefully enough to write my own someday

[@TheOtherGuy-04]

Just started in 2024. Love the tray, I used the hollow one. Thanks for the model and the series.

[@TD3DMakes]

Great video Bryan. Every electrician apprentice's nightmare, memorizing "Billy Brown Raced Our Young Girls But Violet Grey Won" (though there are several crass versions to choose from 😂). Looking forward to trying this out later. Thanks for sharing!!

[@BV3D]

Thanks, Thierry! Yeah there were a handful of not-family-friendly color code mnemonics when I learned it in the 1980s. Next up in the series, we get to play with an RGB LED. 👍

[@dmac6443]

You do a great job at explaining things in a way its easy to understand. Ive always struggled to understand electrical components and so far you are able to make sense of it for me! I look forward to more videos like this and Arduino stuff from you!

[@BV3D]

Hi D Mac! Thanks -- there are more coming, but Christmas is kind of getting in the way temporarily!

[@KowaiPoltergeist]

My girlfriend and I are following your tutorials. You're making this kit so much fun to work with. Thank you!

[@BV3D]

I'm glad you're both having fun! 😃

[@Rob-kr2ir]

My 10 year old son and I have just watched your video and really enjoyed it, we are going to follow all your lessons, thanks for the great lesson !

[@kamrunnazu8223]

Thank you,Bryan uncle. This kit was a gift from my mother's brother. I could't use the dvd. Because of your tutorial I've learned many things about this kit. Thank you,once again.

[@curly-hairedassassin5233]

Thank you for the the informative videos for these projects! I am new to computational electronics and so this new world can be overwhelming., but the way you explain the conceptions really helps. Your videos has helped to assure me that I made the correct choice to pursue a Computer Hardware Engineer degree.

[@rafaelacraizer6]

I have jusr started with the kit and am reeeeally enjoying your explanation! Thanks a lot!

[@mikej8745]

You do a really great job explaining how everything works. Thank you for making these. Love the series!

[@noneofyourbusiness2726]

I’m learning so much, thank you for doing these videos!

[@christophergrove4876]

Again... I appreciate how thorough yet succinct you are. And yet I STILL learned about the flat spot on an LED! ;-)

[@calcarr4955]

Thanks for the videos! Its great that you explain the "why" and not just the "how" of the project. I am very new to coding & electronics and do have a newbie question. In the schematic for this project why is the resistor between the positive side (5V) and the LED instead of between the ground and the LED? I heard you mention (and understand the principle) that current flows from negative to positive.

[@browndog171063]

THanks very much, I just bought this kit and these are fantastic walkthroughs.

[@eccentricnut3566]

I like the delivery & the content. I'm looking forward to seeing where all this will ultimately lead :-)

Never learned electronics. Interesting. Explained in a way that my pea brain can grasp. Thanks.

[@Connor-Colyer]

Thank you so much for these videos, they are so useful as I was so confused when I started out with the kit. Thanks for making it so clear to understand :)

[@jessesmit2907]

Thanks for these! These are great and have a much greater educational value than the included Tutorials do. Had to troubleshoot because I managed to connect the LED the wrong way around. So cool to see the LED light up after connecting the last jumper! Of course, being the idiot that I am I wanted to make a video to send to some friends and managed to connect the jumper to a non-resistor'd connection point on the breadboard. Result: Just a whiff osf something burning, an LED that wouldn't burn anymore and my complete astonishment. That's the story of my first burnt up LED.

[@hail2287]

you never fail to help

[@amiryolo2209]

Amazing video! Subbed and liked! I have a question though, I copied and used the same exact wires as you did but for some reason my led wont light up. Now I can only seem to find 2 reasons why. The red wire which is connected to the breadboard and the 5v port isnt fully connected to the 5v port. There is like half a centimeter of the metallic port part of the red wire which didn't fully go inside the 5v port. The other reason for why I can see it wont work is the yellow led flashing from your first tutorial. I remember you saying that whenever you use the Uno R3, the yellow light should always do its "factory" flash but my UNO R3 is still flashing differently from the time I coded from last lesson. I tried to reset the Uno R3 twice with the small red button but it is still flashing the same way that it did from when I coded it. Do you have any ideas? Edit: Nevermind I just realized how to fix it. I was using the wrong side for the led port. Thanks for the video anyway!

[@omarsantiago6979]

Fantastic tutorials and information!

[@3dmedicvince449]

And if you are subscribed just double click so you stay subscribed.... and to think how much money I spent on college for an associate's degree and all I had to do was wait 30 years and watch your tutorials.... great video and put in an easy to understand way.

[@BV3D]

Haha! Thanks! I did the associate's degree 30 years ago too. I did electronics stuff, built a tiny ROM out of diodes, and wrote assembler on a Heathkit trainer with a 6800 CPU on board. 😉

[@revolutionaryfrog]

Thanks for this series. I'm at the advanced level of Java and OOP but the beginner rundown of arduino C code surely helps. Thankfully a lot of logic operations like for loops are the same as java! Also I checked your Spring store for t-shirts and I wish I had that cool Taco Nasa t-shirt haha.

[@ComplexVariables]

Walking through with my kit. So far, so clear!

[@0nem1leh1gh]

I'm an Arduino owner and i will try it these days.

Brian did you print your blue breadboard box or did it come with the kit, mine just came in a cardboard box

[@BV3D]

Hi Andrew. I printed it. I have a link to the printable file in the description. 👍🏻

[@tonycstech]

How low of a resistance can the board hold ? Can it survive short circuit on a 5v line ?

[@matthewwilson7687]

Do you have a 3D print for the mega 2560 starter kit? I like your set up so it doesn't short out. Right now I am putting the MEGA2560 on plastic it came with. Also, enjoying these lessons! Keep em coming and I hope they all work the same way!

[@apeterson23]

best tutorial for the newbie! Thank You!

[@jshook]

hello, what programming language is used by the IDE, specifically?

[@BV3D]

Hi! This is from flaviocopes.com/arduino-programming-language/: The Arduino Programming Language is basically a framework built on top of C++...The main difference from “normal” C or C++ is that you wrap all your code into 2 main functions. You can have more than 2, of course, but any Arduino program must provide at least those 2. One is called setup(), the other is called loop(). The first is called once, when the program starts, the second is repeatedly called while your program is running. We don’t have a main() function like you are used to in C/C++ as the entry point for a program. Once you compile your sketch, the IDE will make sure the end result is a correct C++ program and will basically add the missing glue by preprocessing it. Everything else is normal C++ code, and as C++ is a superset of C, any valid C is also valid Arduino code.

[@sjappliance]

Thanks, just recently added a led light bar on my van and added a lighted switch that can be lit all the time or only lit when the bar in on. Want to add a resistor to the wiring as it has a spdt switch to the led so it's on and dim at night but fully bright when it's lighting the bar light. Making the switch visible at night and knowing the light bar is on or off.

[@VinciWare]

your videos are amazing. thank you!

[@mortimerq-pencil2513]

thank you these videos. I just recently got one of these kits.

[@antonioluiz3057]

Great lessons! Greetings from Brazil.

[@sn2477]

Hello Brian. Awesome lesson. One question i do have is that you explain the flow of electricity at 11:40. The flow of electrons are from Negative to positive, so shouldnt current flow from positive to negative or in this case pointing towards the direction of the arrow against the wall?

[@70defpure]

Great video, if you were my teacher in highschool I would have learned so much more!

[@SteveH-TN]

Thanks for sharing this video. Back in the 1950’s my mom was happy to have me as excuse to get a new breadboard to use in the kitchen 😀 I’m glad you included the origin of term Breadboard. I have explained it many times over the years. Much of your lessons are review for me , there always something you explain “refreshs” ⚡️⏱️⏱️my memory. I appreciate your time🌞⚡️Update received my Elegoo Super Erduino Uno Starter kit a couple of days ago! Successfully using the IDE, enjoying modifying Sketches and watching the results. My years of experience working with hardware & software developers is really helping as I explore 😅😅

[@jesusfranco5198]

This great.....!!!! I was struggling with this, but you made so clear and understandable. thank you for the lesson. =D

[@Old_SDC]

I’m sorry if I’m being dumb but does anyone know how to tell the ohm of a resistor (without a multimeter) by looking at it? For some reason mine weren’t labelled Edit: forgot to mention, great tutorials man! Just got my kit and I really appreciate it. Edit 2: I’ve figured it out! I just watched the video and noted it down as I tested and watched

[@doujaunlester5196]

Same did you find out

[@jeff2788]

Do you sell the trays - right now no 3-d printer - just getting into electronics.

[@whydoiexist3896]

Hey i like your tutorial, but what code is for the led, what library do i need?

[@aiymankhan7222]

So when you say DC electricity flows from negative to positive, does it mean the 5v terminal on the Arduino is considered a negative and the ground is considered positive?

[@techtrain2996]

It seems the elegoo website is down any idea when it might come back up?

[@BV3D]

It seems to be up now. I was able to go to www.elegoo.com/pages/arduino-kits-support-files and in the *UNO R3 Starter Kits* section, I was able to download the *ELEGOO Arduino Uno Project Super Starter Kit* files. Elegoo seems to update their site all the time, which is both good and bad. It's good because they're keeping things updated, but it's bad because it makes it hard to link directly to a specific page in their site. 😁

Thank you for this video series. I printed out your 3D stand for 12 dollars at the local library. It works pretty well though I don't know exactly what to do with hole parts. The hole closest to the 9v connector didn't line up exactly but I still really appreciate you sharing it. The stand has been really useful so thank you for sharing that. I wish I knew what to do with the hole closest to the 9v connector and what to do with the hole closest to the "ON" led which is diagonal from the previously mentioned hole. I assume there is some kind of screw that goes on both of those but a video would be really nice... is there a way to redeem the mismatch? Thank you so much again.

[@markmorgan1116]

[@oldgamer1330]

Hi,I have a little problem where I converted my dash lights on my car to Blue LED's but the way I had to mount them meant one is further down the tube making it closer to the dash text so this one appears a bit brighter than the other one, could you suggest what resisters I could try to reduce this one to get them to match. They are 12 volt 5w T10 plug LED'S. Thanks.

I love and hate how he talks to us like idiots because there is some stuff I think we know and he is explaining to no one and there is stuff I should know but don't so I am thankful that he explained it

[@Kevin-ig7qr]

Great Video, but he said that electricity flows from negative to positive, NO, thats the flow of elections but the flow of conventional current which is electricity, actually goes opposite, from positive to negative. He also said that in the diode, current can only flow from the barrier to the arrow, its actually the other way round, if you think about it its like a funnel. He probably knows this and just said it wrong by accident.

[@BV3D]

Hi Kevin! Cool! Today I learned the difference between Conventional Current and Electron Current. "In 1752, prior to electricity being identified with the electron, Ben Franklin chose a convention regarding the direction of current flow. Franklin assumed that positive charge carriers flowed from positive to negative terminals. We now know this is incorrect." source: web.engr.oregonstate.edu/~traylor/ece112/beamer_lectures/elect_flow_vs_conv_I.pdf For some reason, I've always thought in terms of electrons (and therefore electron current), and so that's what I'm referring to when I use the word "current" in the video. 👍
