These videos are great
please reply,, if we can use just a potentiometer to adjust voltage then why mosfet like lm317 is used with potentiometer to build adjustable voltage regulator?
@@ankitysabha2577 Remember Ohms law. If you adjust a pot for resistance then if Current changes, V changes and vice versa. Yes you can readjust the pot but a Voltage Regulator does this adjustment automatically. (A voltage Regulator like the LM317 is a little more complicated than a Mosfet)
Codnmore please don't stop these videos, I'm so pleased with your tutorials about the basics of electronics, I'm learning everything's from you! I would love to see the series continue. Thank you so much for the wonderful time you spend showing us something special to learn.
By far the best instructional videos I've seen so far for anyone starting out and just trying to understand certain gadgets. You should be a teacher in this field as you are truly great at it and have a warm approach. Great job!!! Thanks for your effort and young wisdom.
Basically I watched the whole series at once, I loved it and i look forward to the next videos! Congratulations for the great job!
I watched this whole playlist this morning, and it's exactly what I was looking for! Thanks for posting these, I sure hope you continue!
I'm so happy that I found this tutorial. I started playing around with Arduino recently, but I'm wanting to go further and build my own stuff. However, I'm a painter and have very little clue about electronics and how (and why) they work.
You've answered a ton of questions for me that I came with. And, you've also created a lot of questions for me as you go along. But you always answer those questions. And I greatly appreciate that!
Hey Bro I just want to say you are amazing and thank you so much. I have wanted to learn electronics but it is very confusing. But with you I finally started getting it. Something about the way you teach it. You don't bore me, you have tones in your voice that keep me alert. And I just wanted to tell you I bet you could teach anybody anything. Your a really good teacher and thank you for everything. God bless you
Adding to the thanks, I've recently become interested in electronics as a hobby and this series has been a great starting point to get me going. many thanks for taking the time, best wishes!
This is a superb series of videos I am learning from zero but you have a great form of teaching and I am getting a huge amount out of this course. Thank you for your hard work!
Good teaching - you don't rumble, you keep the point in focus. Well done.
I have a brand new interest in electronics, so I've been watching a lot of videos on the subject. This series of 18 is super informative and your style of teaching is the perfect mix of knowledgeable and humble. Thank you so much!
Awesome about how potentiometers work based on varying resistance and the "wiper" and the schematic too. Thanks again for the info!
You have done a tremendous job for d people who want to learn basic electronics in an easy way.
Hello. I have bin watching your videos, as they are the best beginners guide to circuitry on RUclips. Got to this point really excited to continue to see this was the last video :-( and it was May since you last uploaded to this series. Big thanks hope to see more :-)
Cheers mate. Just caught up with your series, looking good so far! Nice resource.
I am racing through these tutorials, they are great!!! I am so looking forward to making the 8 bit computer at the end of the course!! Exciting :)
I know you don't know me but I appreciate you taking the time to explain these tutorials. I'm glad I ran across this because I just wanted to dive in but obviously I needed this.
I'm right there with you :D I haven't touched any of this stuff in quite some time, and it's great to have a refresher.
Guys btw, just a little reminder but before using a potentiometer anywhere just remember potentiometers can burn out just like LEDs, but not the way LEDs do. When a potentiometer is burning out smoke literally starts coming out of it. It can happen when you turn it too much to the far right (to the direction of the third terminal) and too much current is passing through it. So be careful because I learned this the hard way.
your tutorials are awesome. it really helps me. waiting for the next videos.
Also waiting for the next video! ToT :( I'll even take once a month! XD Just please don't stop this series, because it has helped me so much! Thank you! :)
PLEASE CONTINUE THIS SERIES
Wonderful videos. I could easily complete following videos in two days. Please post next videos.
You are great mate! Looking forward to more awesome and well-explained videos! Keep it up :D
So this is what a dimmer switch in my house basically is? A potentiometer! I learned something new
maybe the fan regulator too
The 'safer' thing to do here is to use the 240 Ohm (220 would do) Resistor and the potentiometer, in series, since the Pot can go from 0 ohms (short) up to the measured 1MOhms. This sill prevent the LED from burning up when the pot is wound down to 0 ohms.
Amazing tutorial, I have learned a lot, but still waiting for that 8-Bit computer tutorial which I was excited about since the begging of the series.
me too, im want to know where are the rest of the videos that leads into the 8-bit computer
Fernanado Ortiz I really now want to do the 8-Bit computer more to use a open-source API to create a FTP over TLS connection in C. The 8 Bit computer would be used to do simple things such as turning on and off a lightbulb.
@@JoseGonzalez-rt5fkhello it’s been 7 years have you built it?
12:02 - Best part of the video!
Hella helpful stuff, keep doing your job man!
If you're not dead, get back to work! Ep. 19 pls =(
u said it...😀
Lol I love this comment 😂the amount of worry is and hurry is perfect
very good explaination thanks
Everyone talking about 8 bit computers and we haven't gotten to ICs yet.
Was this the last video? All great videos! Thank you very much!
Amazing tutorial...waiting for the next one.make it possible soon...
You are doing the wonderful job. It is good if someone want to lean the Electronics. Well I have a request for you since I am following all of your videos of Electronic Learning and I could see in every video you will introduce a new electronic equipment. As you are going to make 8 bit computer so can you list down all the equipment accessories which we need to purchase it at once, so that we will be ready with all the stuffs also it will helps us to sync with all videos.
Thanks in advance!
You've cleared my all doubt regarding potentiometer
mayb its too fast too think this way, but im actually starting enjoy learnin electronics.
Im a mechanical engineer but im really not good when it comes to electronics...
cant wait for the next episode:)
Thanks for this video 💐🙏👍
Please make more videos of this 🙏🏻
Thank you very much
So an open push button is the same as a morse key. When it is pressed down it makes contact when you release it contact is broken. You can use a potentiometer like a volume dial to increase or decrease the resistance but I noticed you mentioned that they can come in two forms: linear or logarithmic scale.
Great Series just at 1m 51sec a tactile switch is only one switch as the legs are paired (continuity through them) which is useful too
surely you need a resistor in series with the pot in case you turn it past 240Ω to zero otherwise the LED will burn out?
Brilliant!
Hi, thanks for the potentiometer tutorial! If you wanted to avoid burning out your LED I was wondering if you could add another resistor to the circuit to first bring the current down to the maximum the led can handle, then if you set the potentiometer to max it wouldn't burn it out - would that work? Cheers
You are very good at this, a pity it can be years between episodes.☹️
So I might not have been paying attention but I think this is the first time you've used the term "ground"? Ground is the negative end of the battery? Does it even have to be the battery as long as it's something negative?
At the beginning of the video my immediate thought was, "how do you reverse the resistance of the potentiometer?"
By which I meant: "It seems to me that if you turn it clockwise, you should add resistance, so if we connect an LED to it, turning clockwise would actually dim the light, and that would be weird."
Then, with your diagram at 9:00 I realized that you would connect the circuit to the other side of the potentiometer, so that if you turn it clockwise, you're lowering the resistance on the side that holds the LED, thus making the clockwise turn allow the light to get brighter. As god intended. lmao
I was also wondering about using potentiometers in such a way that will prevent burning out a component. Then I realized that you should use a resistor first to ensure that it doesnt exceed the maximum voltage, and then use the potentiometer to safely control the voltage with a set upper limit.
Thank you😊
Super video
That sofa king cool thank you so much :') 🙏
so to be safe and not burn out the LED you would typically use a regular resistor to Get the LED at safe full bright how you want it then add the potentiometer as only additional resistance to the circuit?
Oh and by the way, anyone watching these videos out of the US (like me, from the UK) remember that the symbol for resistor is probably a rectangle instead of a squiggly line. Just a heads up!
Ur good teacher
I just spent the morning following along with your great beginners electronics series, I've reached this video and wanted to continue and noticed that there weren't any more videos left to continue to. This one was released may 9th, and it's already august 5th. Are you planning on releasing more of the series or is this an abandoned project?
Yay!
Hello, thank you so mucy!!!!
Why dont you put a resistor between the potentiometer and the led to avoid burning it out?
why do you add register after led and some times before led please tell me I'm confused
hey :). awesome tutorials dude. Are you releasing a new video soon? please do. Like they mentioned at the bottom of the comments, I'm excited to build that 8 bit computer.
The tactile button which has four leads is a double pole button?
can i swap a 6 leg pot with a 3 leg of the same resistance? My treble pot on my amp is getting real bad, and i have a great 3 leg to use if able.
it's a momentary switch !
I would say this is 66% of the true explanation because the variable resistor aspect is kind of incidental use of the potentiometer. There is a reason why it's called a "potentiometer", from the word "potential", electric "potential", i.e., voltage. The middle connector can be varied in position to give one a variable voltage, given the two end connectors are connected across a voltage source. This configuration is commonly called a voltage divider: the center voltage = V * R1 / (R1 + R2) where V is the voltage source connected to the high and low ends, R1 is the resistance between high and center, and R2 is the resistance between center and low. By moving the center tap, variation in voltage is achieved. This is the more prevalent and intended use of a potentiometer.
This is so amazing, really looking forward to the next one! This might be a very stupid question, but at the end when building the circuit, where is your power source? I don't see any battery plugged in or anything..
It's probably plugged in at the far left of the breadboard whcih is not shown on the screen
WHY your vids are getting less and less views.i feel bad about you. You work so hard and your work doesn't get enough attention. your tutorials worth more than a shitload of diamonds
because not everybody finishes what he or she started
@@shakhzodkhamidkhonov8164 thats a sad truth
Thank you. Out of appreciation I watch all adds so you can get some money.
When is the next part of this great tutorial series? Its been great up to now.
Wednesday this week! Then another the next week!
YES!!!!
Cool! 😊
where is your power source in the breadboard for the circuit at the end of the video?
please reply,, if we can use just a potentiometer to adjust voltage then why mosfet like lm317 is used with potentiometer to build adjustable voltage regulator?
Where do you buy your components?
thanks bro
But I used potentiometers to measure accurate voltage using the position of null point. Why this one is also called potentiometer, it should be something like variable resistance or rheostat... little confused
When you turn to the right and are increasing resistance, why does the LED light up more...isn't there less current going to the LED?
14:31 I have a question about this point in the video. Why do you call it "ground" and not negative? Thank you so much for the great video lessons, I'm learning a lot!
same thing
Actually the red wire is positive. Thats standard with wires btw. Black is negative (providing electrons/power for simplicity sake) and the red is positive (drawing the electrons to it and back to the power source). Grounding is another way of referring to a 'common return path' (unless you're talking about literal grounding to mother earth which neutralizes it to 0.
To clarify: What he means when he's "grounding the wire" (using the positive wire) is that the electricity is being provided by the (out of view) black wire coming from the battery. That wire is supplying the voltage through the component and the resistor/potentiometer. It is then traveling through the red wire/common return path/ground where the circuit will be completed and there wont be any openings in the circuit waiting for your finger to complete the circuit and shock your ass.
So when it is being "grounded" he simply means the circuit is being closed so to speak.
This is my rough understanding of it. I'm sure there is more to add on this subject but that's a good way to think about it. Don't overthink the details on this -- just know that whether it's the black or red wire ending the circuit, both can be thought of as "grounding it" once the return path has been finalized. Even though neither wire is REALLY referred to as a grounding wire. That's normally a 3rd copper wire that literally grounds it to the earth to protect from MAJOR spikes (such as from a lightning strike). Because mother earth can receive all of that power with no problems. Your little LED light or battery not so much.
These tutorials are great for learning electronics basics. I was wondering if you're planning on doing a video on making a circuit without a breadboard for something more permanent?
+Justin Keskel there are some great perfboard/soldering tutorials, but I may do some as well for permanent designs :)
+CodeNMore thank you very much for this course, i learned many things here and i am willing to learn more from you, but i have to ask whats your plan for this series? Once a month?
Wait are potentiometers used to measure volts? And aren’t rheostat variable resistance?
14:31 why did u say u connect to the ground when u connect to the negative? Does ground and negative the same ?
Do you guys also see Kenny from South Park in the potentiometer sketch? :D
PLEASE give us a link to your multimeter
how does led glows without power supply
does copper wire work with breadboards?
AT last part where is the battery , without it how does the LED glow ?
when will next video come?
Would it not be better to add a resistor to the circuit such that that resistor + the minimum resistance on the potentiometer add up to the minimum resistance needed for the LED? That way, there is no risk to turning the potentiometer to any setting.
Please sir come back
Is there a lesson 19?
MY ANSWER:current in each parrelel wire
1) 1/4 Amp
2)1/2 Amp
3)1 Amp
please upload more video about electronics .thanks you so much code and more for clear explanation. iam waiting for your new video about electronics
@CodeNMore Why did you stop making these tutorials? I am waiting for the 8 bit computer:(
magic!
One question that concerns me is, why is the LED connected before the resistor on the positive part of the circuit? I may be wrong, but wouldn't the jolt of currant burn out / damage the LED? Can a circuit work if you put the resistor first?
Sorry, I think I missed a big point, as the circuit is pretty much instantly complete when terminated to the power source
how did the led work without a power supply, and why is the middle terminal connected to ground? please explain
The power supply is offscreen to the left - the power rails run the entire length of the breadboard (the 5-hole groups are NOT separated). The middle terminal is the one which allows you to use the adjustable resistance of the potentiometer and it is connected to the ground/negative terminal of the power source in order to close the circuit.
Where’s the power source of the experiment at the end? How does LED light up without a power source?😕
Where's the voltage coming in the final circuit? I didn't see no battery! thx
Probably offscreen
We have not connected voltage source in this video then how led glows up??
4:23 Wouldn't that last one be a double throw? It has only one circuit connected at any state, but it has two positions.
Single pull double throw means one input leads to two outputs. Double pull single throw means two inputs where each input has 1 output. Aaand since that button has 2 inputs, with one output for each input, it is a double pull single throw(or just double pull for short).I hope I made sense.
i cannot send you a PM i need to ask you something about a project im working on
When do we get to Redstone :)
Do we have a double pole double push button???
make more videos as fast as you can I want to learn as much as I can so please make them all to 8 bit computer as soon as you can thanks
Does it matter what order the components in a schematic shows up in? Because the schematic you draw has a LED before the potentiometer....how does that work out
No it doesn't he already explained it, it's same as resistor
