@@judo-rob5197 When I was getting my Computer Science degree, we had a book called Programming Proverbs. It was a small about 6x9 inch paperback loaded with good advice. One of the proverbs that I always remembered was "Re-read the manual". The point made was that there is a lot of stuff that goes over your head the first time around. In a lot of cases that is because you haven't a clue how to use a particular feature. After you have been at it for a while, the feature in question may be applicable to something that you are trying to do. Case in point: I had not been aware of how to calculate the current limiting resistor value before I saw it here. I just always used what I picked up a long time ago which was the rule of thumb to use something around 270-330 ohms. That, I now understand to be because everything was 5V TTL back then and those values worked out for the LEDs that we were using.
Thank you, thank you. UA-cam is full of these explanations, but your video is by far the best. Simple to understand without any presumptions from the viewer watching. Awesome video. 👍😎
I like to say “if I haven’t seen it, it’s new to me!” I’m other words, I’m going to watch because I know I will learn something. Love your vids! Keep up the great work. Peace!
Really appreciate the patient explanation and demo. Thankyou. My reason for looking up electronic tutorials is because I wanted to understand what might go into modifying a radio to add back lighting for tuner dials and to add mp3/ Bluetooth modules to enhance radios. Lots of good stuff in these videos to show why I shouldn't bother buying a solder kit. Better to find that out before investing!
Hi Paul: Finally a explination in laymans terms. I'm going to make up a chart from you drawings as a reference for future LED wiring. Thank you so much. Chuck
It may be basic but this was VERY good. A lot of things work, but this was a huge help to really understand the correct way to use LEDs. Thank you for your efforts.
I’m glad you did this video. I know there are a lot of people out there that will need it. I enjoy all of your videos even if I think I’m very familiar with the topic… You still teach me something every time!
I think like a lot of people, I have somehow managed to fudge my way through life without ever learning the true basics of LEDs... thank you for putting this right.
Great video, I happened to learn a thing or two about LEDs that I somehow never seem to come across. Thank you, and for all the videos you put out which have tons of knowledge for beginners to your Big Clive's 😂👏🏼
I think you accidentally mis-stated Ohm's law as V=I/R at around the 10 minute mark, and at least once later. V= I x R, of course. You still get a thumbs up, though.
Nice video. Really helpful. Only criticism would be the way you state Ohm's law. V DOESN'T equal I over R. When you did the calculation you used it correctly: V= IR
As someone who hadn't thought about annodes and cathodes in 5+ years (GCSE chemistry) and is trying to learn electronics, this is so useful! especially as i don't understand your other vids as I have no clue what's being said, but I'm learning!!
Good job on this. I am retired electric lineman and now wondering what kind of projects I can do to keep my little brain working. Thank you for the good lesson on LEDs. Do you have any suggestions on power supplies? Thanks again,
Thank you so much for this video, I've got an LED project I'm going to work on and gathering as much information as I can on it before I start and this was very good for setting some ground rules for me.
Thanks, my white led was shutting down my orange and green in a parallel circuit. I didn't know the advanced voltage was even a consideration with LEDs. awesome thanks.
Thanks for anther great educational video.. there is always something to learn from you eg the internals of a diode. I know the basisc of electronics but i often dive into the beginners titled vids to see what knowledge pple pass on. Cheers from Down Under..
Blowman...in your demonstration...you've blown more discrete LEDs than l've been able to come across as a diy enthusiast, liking Texas Instruments, Forrest Mims Project books. You have a interesting and informative method. Don't take the "blowman" comment as a insult...it's just something we workers would say to each other in a battery plant. Congratulations...l subscribed!
Great video Mr. !! You killed 3 innocent LEDs for imparting your knowledge to the world ! I'm subscribing to your channel right away. Love from Singapore.
Something I learned from AvE (I think) years ago that lets you instantly remember which lead is positive on LEDs or electrolytics: you can create a + sign with the longer lead by cutting the extra length off and turning it sideways. Physical memory tricks like that have really helped me along the way. Another one I just remembered is how to remember which wire is live and which wire is neutral in US home wiring: put the two wires out in the sun, the black one gets hot and the white one stays neutral.
In the real world component leads are often trimmed so you cannot count on one being longer than the other. So you're better off looking inside the LED to see what polarity it is. There you just remember the bigger bit is the ground. I also equate the bigger bit to being the "land". I've heard of anvil and post but that has no meaning to me. Land on the other hand is earth or ground.
Fantastic video, very concise and informative. You answer one of the most basic questions for enthusiast looking for a simple answer regarding LED's. I subscribed and going to go through your other videos, little refresher never hurt anyone, even someone whos been into electronics for 30 some years.
Thank you for this information. how do I calculate the power needed to make a sign like great Scott. I want to make three signs. Man cave, she shed and war room. Is it better to run them parallel or series? How do I figure out what voltage I'll be needing?
Interesting,. Looking to find a video to explain the resistor size needed to drive some 0.5W LEDs I just got off of allyexpress. Sadly only information I've been given on them is that they are 1/2Watt, and voltage. How do I convert Watts to amps
My 'UV' leds I harvested from a nail polish curing thing have a forward voltage of 7.3 volts. measured on a keithly dmm-6500 cause that seemed high lol
What’s the difference between common cathode versus common anode LEDs please? I take it one works the way you show and the other is reverse of that? Am I correct in thinking this?
You are listing the voltages for each color, are we to assume the the amperage is @.20ma? If this is true why do your voltages not match the voltages listed on the 5mm case chart that you showed us? As well as looking at the manufacturer standards sheet, I noticed your voltages do not match. I like my LED intensities to match and voltage is important for that to happen.
great video.ez to learn the way you do it. can you do or explain to me how this would work if youre powering a clock LED bulb under AC power 120V? i calculated a resistor like 11,450. is that possible. did I do it right?
Thanks for this video. Could you do the next stage ,that is , lets say, running 4 of the same Led's in the circuit. Daisy chained.. against running the 4 in parallel?? I would find that very helpful. Best regards Don Codman
i got two kinds of red led's one is 800mcd 1.7v 20ma the other is 5000mcd 2.3v but does not mention ma? i will assume 20ma, so anyways i use these in a light in the dark floater i made for night fishing and usually hook them directly to a 3v cr2032 battery is this ok? because that is the lightest battery at the closest voltage i can find besides i calculated one needs 65 ohm resistor and the other 35 ohm so is this negligible enough to say maybe the battery has enough internal resistance to proximate those amounts? anyways it's been working fine so far
Indium gallium nitride (InGaN): blue, green and ultraviolet high-brightness LEDs Aluminum gallium indium phosphide (AlGaInP): yellow, orange and red high-brightness LEDs Aluminum gallium arsenide (AlGaAs): red and infrared LEDs Gallium phosphide (GaP): yellow and green LEDs
@@learnelectronics That's what is inside the divot in the anvil die is Indium gallium Nitride for blue and green? I'm not sure what the Bonding wire does that is bonding the post to the anvil, what is that bonding wire doing?
tell the truth, you were looking for an excuse to ope n that new box of LED's. ; ) "I love back to basic's," I think your the only one who do them! IN FACT IM SURE OF IT. never stop doing them!! i think you can guess what comes next "COOL VIDEO PAUL" : )
great video, nice to be refreshed on ohms law .. may i ask a question .... if i was using 9 led's, in series .. do i need a resistor for each led? or does 1 resistor work the same and what wire needed for a 9v current .... any help would be appreciated , thanks.
This was basic, This was cool, The way electronics should be Next .. probably a good idea to teach them connecting LED's in Series with calculations then Connecting LED's in Parallel with calculations Maybe go into LED strips for them with IC so they understand how to test them I recently had people asking me how to test LED strips that they thought were faulty but didn't realize it had a built in IC
Is the flow NOT that of electrons, flowing from ground to Vcc? ... The USN taught me that this flow contradicts the schematic arrows which are depicted in diodes and transistors (etc.).
I always watch the beginner videos because I always learn something that I missed before.
Me too. Never over estimate your knowledge on a subject. I learned several things from this beginner video.

Got to love LED's my favourite component
This is more informative then them other vids. Thank you

What is it inside the LED that glows? Is it the die? or the jump of current from the post to the anvil? of the bond wire?
these are awesome. now do capacitors. thanks Paul

Keep up the good work
My 'UV' leds I harvested from a nail polish curing thing have a forward voltage of 7.3 volts. measured on a keithly dmm-6500 cause that seemed high lol
so what would happen if you was running a few leds say 6 in series surly that would lower the voltage on say a 9v batt how long would the batt last ?
Thanks for the info, very helpful
why do some ppl use transistor to run these from a 9v battery instead of just using resistor(s)? is the trans really necessary?
cool but can you give me the link to where to find those tiny leds
