@tomx63 if he is using 12 volts there is a higher Mili Amps, in this case probably is Amps which is higher and that will make the circuit to heat up and make the resistor blow resistors to resist current ( amps) and thats why he need a resistor with higher watts or he can use two resistors to double the watts. believe me he will still have enough volts + hes LED only needs 20 mili amps.
@JeepOn94 if your Led is 3v on a 12v source one resistor won't gonna work voltage is to high you can try 2 resistors one on (+) and one on the (-) higher Watts ans tolerance
Hello i have a question so i have 20 red 3 watt led and 10 blue 3 watt led with a 100 watt led driver so how i can mount can i mount this without resistor in parralel ??
trying to wire a LED light into a 12v source and my resistor keeps blowing. I used the online calculator to figure out the size of the resistor but it doesn't seem to be the right one. Any ideas?
This was a very cool video. Thank you for making it. I'm interested in making a 300 LED light string to use on a Christmas tree. Where would I buy the LED's and resistors in bulk and has anyone tried this?
i have a 12 volt battery pack and using 12 v LEDS ......how should i set up my wiring scheme. i am guesssing i'll use about a 400 ohm resisitor for each bulb or connetc 3-4 bulbs in series with a 800+ resisitor
You need to use forceps to dissipate the heat from the soldering iron. You have to avoid burning the LED leads. They're susceptible to damage when that much heat is applied.
noobie here to electronics, im interested in making a 3 or 4 point led hat for free track, i got the led's / resisters and a 6V plug in power supply, so from your video would you recomend power + to resiter to + wire to + led than from the - led to the + of the 2nd - to + to the 3rd led than the - to the - part of the power supply and thats it right? or would it be better like you did in your video and solder the resister to the first led than that to the + wire to the power supply, does it mat?
Hi there, I am very very new to LED wiring. I am familiar with which resistor I need, but does it matter which type of solder I use? Does wire gauge matter? If I want to add a switch, can I use any small switch or do I need a specific one for the wattage? Sorry about these noob questions, but I can't find the answers anywhere online and I've been looking for hours. Thank you for the vid, it is quite helpful.
Great demo Q: How can I learn to replace a LED for a surge protector? I can't seem to find the right key words to help me find help. I have everything i need I just need to know how to correctly do it.
Radio Shack if you are willing to order, but they sometimes have basic stuff in store.
Also no joke check IKEA. They sell dirt cheap LED lamps and various LED lighting . Stuff with inline dimmers and switches you can use for easy stuff. Around eight months ago they had these Jansjo LED twisting neck lamps for $9. I removed the bases & re-wired 4 of them to light up my guitar amp head bright green.
They have solar ones too. I have been considering stuff using them.
Thanks man perfect little video to get me up to speed id like to put a full led tail light retro together in my car. I already did it using led strips but i would like to change it around a bit. Also i want to put some forward face leds in my kids power wheels escalade headlights
@Celiecinema1 Then what ever you have it connected to isnt too high voltage. I have some wired to my sub, which is higher voltage, anythin above live 5volts/9volts might burn out your LED. the resistor simply takes high voltage and makes it smaller to safely power small devices like LED's. Like an iPod charger, the 240volts coming from the socket in your wall gets knocked down to about 5volts by a resistor to safely charge you Pod :)

He had a hard time soldering because he put the solder on the tip then tried to put it on the connection.

hey thanks for showing ho to wire a led but, could you make a video on how to wire a 7-color blinking LED i got from radio shack on a continues changing mode? thanks.
Dude thank you for making this video. Lol I just got a 2000 Hyundai Tiburon and I have been trying to put LEDs in it. And this is the first thorough explanation video that I have seen. Thanx
There's a problem with the wiring; shouldn't the resistor be on the negative side of the battery, since the electricity is going from negative to positive through the LED? The electricity is going out of the negative terminal through the LED, then through the resistor and to the positive terminal.
there is no correct way in which electricity flows. Some may say from positive to negative others say from negative to positive. In my theory since positive is the "hot" side and which is where electricity is coming from in a sense (since you cannot receive power from a negative terminal) i put the resister on the positive lead...it seems to work well though im sure even on the negative side it would work as well.
@Famoussasdrummer182 Interesting, I actually heard somewhere that it's always negative to positive, but then again I've heard it the other way around as well.
@Famoussasdrummer182 the definitions are confusing i agree, but dc current flows in one direction..if you dont connect some more sophisticated device correctly you can burn it
For the record, on an atomic level electrons actually flow positive to negative although in most applications related to engineering the conventional positive to negative model is observed. In this case it makes no difference which side the resistor is soldered into because it still serves its purpose of impeding current flow. The electrons may arrive at the led faster but they must still depart at a slower rate, reducing the current observed at the led
The electricity is "going" from negative to positive, because current is the displacement of electrons (-). most of the time, we say that it goes from the positive side to the negatice side, but it's only a convention. It dosen't matter where you place the resistor because it has no polarity(it works in either way)
@Famoussasdrummer182 LOL, in theory, when you guys say Positive to the Negative is known as the conventional current. However, in reality, it's Negative to Positive. But because of it's long reliance on the Conventional current, it was still accepted.
You are correct; current does indeed flow from negative to positive. However, it doesn't matter where the resistor is placed. The current will be the same whether it's on the positive or negative 'leg' of the circuit because - and this is important to remember - current is the same at ALL POINTS in a series circuit.
@xaenon I actually built an LED circuit, but it was good without a resistor, believe it or not. The input voltage was only 4.5 volts. It hasn't blown yet and it's working fine!
Yes, some LEDs are made to handle specific voltages, typically 6V and 12V, because those are fairly 'universal' device voltages. The 6V models work well with computers (like the HDD indicator of your PC) while 12V LEDs are good for automotive applications. As a general rule, specific voltage LEDs used for 'indicators' have a resistor built into the 'capsule', while 'illumination' LEDs (flashlights and the like) have higher-voltage junctions and don't need a resistor.
@Celiecinema1 both the led and the resistor are resistances, so their ohmic values add up whey they are connected in series... this way the led+resistor work as a single resistance, and it doesn't matter which one comes first... most of the led schemes i see put the resistor after the led (related to the current directions), in the positive side... probably there is an explanation for that, but it has not to do with the direction of the current, since they act as a single resistance...
People. Stop disliking videos if they don't tell you exactly what you're looking for. He was clear and everything made sense. there is no reason to dislike this video. I'm sorry that he didn't tell you how to connect 40 leds in one strip.
Just saying, you should never put solder directly onto the soldering iron unless you're tinning it. You should first heat up the leads, then put a little bit of solder in the space between the soldering iron and the leads, then go to the side of the leads opposite of the side that has the soldering iron on it and put solder there. If you put solder onto the soldering iron and try and move it from the iron to the leads, you'll get a bad connection. Just saying.
Hey man, cool tut... say... when i want to build glowsticks, what powersource do i use, is a 1,5 V battery (AAA) enough), also, is it possible to add a on/off switch to it? if so whta shall i use?
soldering job: first.. dont solder on fabric, thats stupid. and you're not suppoesed to melt solder on the gun itself, also stupid. secondly, you can just but a 1.5 V battery also known as AA, AAA, C, D batteries. cause from what i can see that led is a 1.5 V LED.
First learn to solder, then make how-tos. You have to heat the part you want to solder, and then move the solder it self to it. Only that way you wil get nice soldering.
hey i just bought a multi colored led and i have some questions on the back in the information it has for values for the different colors and I'm not sure which value to use in the resistor calculator the led also has three legs coming off it and I'm not sure which on to use
@Famoussasdrummer182 I bought some LEDs on Eb@y from this guy in Hong Kong.Anyways Its 2pcs 24 LEDs strips and I was wanting to connect them to the inside of my car.Would I need some resistors for them?Also how would I connect them if one strip of LEDs has two wires coming out of it?
You did a spectacular job, but like the fellow said below where do i get a resistor? I've been paying a shit load on a side just to get leds wired.. this really helps.
dayum can anybody tell mehow to connect three led using a on and off switch and in one line good enough to fit into a glowstick it has to be three led's on and off switch and 12 volt camera battery anyone know????
@thesupahfly: Are you a Brit? Americans pronounce it just like in the vid: "sodder". The only time I pronounce the "L" is when I'm trying to piss someone off (I'm a Yank).
Okay so I put three LEDs together (positive to positive and negative to negative) and the middle LED won't light when connected to the others. Can you tell me what I did wrong ?
it sounds like you were trying to put the LEDs in a series circuit. Connect your LEDs like this (P for positive N for negative)
P N + P N + P N connect the negative leg to the next LEDs positive leg and so forth.. connect your resister to the first positive leg on your first LED
it sounds like you flipped the middle one around the other way
@97bosko You need to use a resistor with some LED's or they can burn out easily. It all depends how much voltage you are using and how many LED's. Look up Ledcalc on google and use their calculator it will tell you what kind of ohm resistors you need.
@besimr I ran 26 flashing LED'S with 3.5 using 1 9 volt battery. I use no ohm resistors because I realized it affected the lights when they flashed. You can run 5 LED's with a 9V for days.
you need to learn to solder, sand your connections, then use a tiny mount of solder on each connection before applying them together. thats the correct way. otherwise you end up with cold solder joints
If you want to know the technical way to find the correct resistor you use the formula r=v/I where r is your resistance (ohms), v is your voltage, I is your current (amps). For this project you get the voltage of the po

The electricity is "going" from negative to positive, because current is the displacement of electrons (-). most of the time, we say that it goes from the positive side to the negatice side, but it's only a convention. It dosen't matter where you place the resistor because it has no polarity(it works in either way)
sorry for my bad english

@Famoussasdrummer182 LOL, in theory, when you guys say Positive to the Negative is known as the conventional current. However, in reality, it's Negative to Positive. But because of it's long reliance on the Conventional current, it was still accepted.

You are correct; current does indeed flow from negative to positive. However, it doesn't matter where the resistor is placed. The current will be the same whether it's on the positive or negative 'leg' of the circuit because - and this is important to remember - current is the same at ALL POINTS in a series circuit.

@xaenon I actually built an LED circuit, but it was good without a resistor, believe it or not. The input voltage was only 4.5 volts. It hasn't blown yet and it's working fine!

@Celiecinema1
Yes, some LEDs are made to handle specific voltages, typically 6V and 12V, because those are fairly 'universal' device voltages. The 6V models work well with computers (like the HDD indicator of your PC) while 12V LEDs are good for automotive applications. As a general rule, specific voltage LEDs used for 'indicators' have a resistor built into the 'capsule', while 'illumination' LEDs (flashlights and the like) have higher-voltage junctions and don't need a resistor.

@Celiecinema1 both the led and the resistor are resistances, so their ohmic values add up whey they are connected in series... this way the led+resistor work as a single resistance, and it doesn't matter which one comes first... most of the led schemes i see put the resistor after the led (related to the current directions), in the positive side... probably there is an explanation for that, but it has not to do with the direction of the current, since they act as a single resistance...

Just saying, you should never put solder directly onto the soldering iron unless you're tinning it. You should first heat up the leads, then put a little bit of solder in the space between the soldering iron and the leads, then go to the side of the leads opposite of the side that has the soldering iron on it and put solder there. If you put solder onto the soldering iron and try and move it from the iron to the leads, you'll get a bad connection. Just saying.

Hey man, cool tut... say... when i want to build glowsticks, what powersource do i use, is a 1,5 V battery (AAA) enough), also, is it possible to add a on/off switch to it? if so whta shall i use?
Dynamitrios 10 months ago
soldering job: first.. dont solder on fabric, thats stupid. and you're not suppoesed to melt solder on the gun itself, also stupid. secondly, you can just but a 1.5 V battery also known as AA, AAA, C, D batteries. cause from what i can see that led is a 1.5 V LED.

First learn to solder, then make how-tos. You have to heat the part you want to solder, and then move the solder it self to it. Only that way you wil get nice soldering.

Okay so I put three LEDs together (positive to positive and negative to negative) and the middle LED won't light when connected to the others. Can you tell me what I did wrong ?
nugent923 1 year ago
@nugent923
hi
it sounds like you were trying to put the LEDs in a series circuit. Connect your LEDs like this (P for positive N for negative)
P N + P N + P N connect the negative leg to the next LEDs positive leg and so forth.. connect your resister to the first positive leg on your first LED
it sounds like you flipped the middle one around the other way
Famoussasdrummer182 1 year ago
@nugent923 u must have connected the middle one in the wrong direction or the led is burned. and btw this is called parallel circuit

97bosko 1 year ago
@97bosko You need to use a resistor with some LED's or they can burn out easily. It all depends how much voltage you are using and how many LED's. Look up Ledcalc on google and use their calculator it will tell you what kind of ohm resistors you need.

you need to learn to solder, sand your connections, then use a tiny mount of solder on each connection before applying them together. thats the correct way. otherwise you end up with cold solder joints

If you want to know the technical way to find the correct resistor you use the formula r=v/I where r is your resistance (ohms), v is your voltage, I is your current (amps). For this project you get the voltage of the po
