Thanks for making this so straight forward! I'm a mechanical engineer student and electrical things terrify me(because they can get expensive quick when you eff up). I was wiring in a new foot pedal for my TIG welder and I couldn't find a simple reason for why my current was at its lowest when the pedal was to the floor. This explained everything! Thanks again.
Thanks so much for this dude. I'm really wanting to get into electronics so now Im gonna get a 9v, a breadboard, wires, potentiometer, and an old pc fan and have some fun.
You are amazing. I dont know if it was you or not but something just clicked in my mind while watching this video. I will just go ahead and give you the benefit of the doubt. You earned your like.
Simple but clearly understandable .. I better go on this kind of tutorial rather than those who have many discussion which misleads the viewer to what he/she is trying to come up with. keep on making such kind of videos.. from the schematic/wiring diagram, to the actual wiring .. THUMBS UP>>
Thank you so much!!! You have no idea how simple you have made this for me. Well I suppose you do considering that was the point of the video. Again thanks a bunch
thanks a lot for making this video iv been wondering how to properly use a potentiometer and how to hook it up and this video really helped me out. you just earned another subscriber
Thank you. You did a good job of explaining for first time user. there are lots of clips with no explanation and lots of music. I must say they should change...
I would use a 100k ohm linear taper. Here's a link for them on eBay. www.ebay.com/itm/5-x-B100K-100K-OHM-Linear-Taper-Rotary-Potentiometers-USA-Seller-Get-It-Fast-/221769445455?hash=item33a27d304f:g:rcIAAOSw6BtVT9tU
Do you hook up a speaker the same way as you did the fan? I'm still a little confused on how it would work in this manner. Audio output from an amp board; has + - How would I hook it up to a potentiometer then speaker? I'm thinking + - from the audio board to the outer pins on the pot. Then the center wiper blade to the + on the speaker and the - from the speaker back to the neg on the pot? It worked with my LED
omfg you are a god.. google has been crap lately and i have been looking for that simple answer for so long! i just got a case with a constant 12V fan controller so its super loud! now i can tone it down!
Hi, I'm building a hovercraft for a school event using a 9 volt battery and some motors. One motor is used as a fan pushing downwards, while the other pushes backward to move the hovercraft forward. How can I use a potentiometer to control acceleration of the vehicle?
If you're talking about scioly, I wouldn't bother using a potentiometer for the lift fan, since the more of an air cushion you have the better it floats~ Just do this for the thrust fan
Good video if I was just hooking up a pot to a led light with the dimmer leads coming out of it . It has 5 wires I think for a bluetooth capability, how do I figure out what three . I have a 50k pot
what is the impedance between the two outer terminals when you turn the fan down?? aren't you effectively creating a short in your power supply? not sure if i would want to do that to a $150 PSU for a computer. that's why they use transistors and end up bleeding off heat in the other "simple fan controller" setup.
Would that wire diagram work to wire speakers to a radio? The radio volume control is stuck on high. So I figured it's easier to just wire it with an auxiliary potentiometer outside between the speakers and car output speaker wire. What do u think?
omg this is what i needed. im learning electronics at home fun fun as a passion . the pages i went to online a few said different things. this straight to the poiny.
Can I use a momentary linear potentiometer in conjunction with an Arduino, AVR, PIC microcontroller, or Raspberry Pi to light (6) 12 volt LEDs simultaneously? (IE: lights the first LED and maintains it, then the second, third etc. The LEDs would then turn off simultaneously as the potentiometer returns to rest.)
Hello, is there a resistor or something to restringe the voltage like 18v to 9v or 12v to 7v etc; without going under 7v ? Tks. And what potentiometer value Tks.
perfect, just what i was looking for, thanks. I've done this for 12 volts and worked just fine,but what size resistor would i need for a 100k pot with 24v and a max of 18 amps? and where should it be placed? Any help would be appreciated, thanks
M a little confused by your question. You shouldn't need a resistor with a pot as the pot is simply an adjustable resistor. You don't need to limit your Device at 18 amps as the device will only use the current needed. It's not like voltage.
Oh ok so a 100K pot would work just fine for adjusting my 24v power supply then? Sorry, I'm just starting out here with a little knowledge of electronics. Everywhere I see people are screaming lm317 to regulate voltage. Thanks in advance for the reply
pls help my pot has 5 legs,it said that it is audio/video pot in description,i followed what u said,but it did not work,is it the problem with pot or my 9volt battery.can we use 9volt battery as well?
You can't really use a pot with an AC motor. Because of the way a fan/blower motor (shaded pole induction), the fan wants to run at a certain speed as it chases the polarity/waveform of the input voltage. You can buy a fan controller switch at a hardware store but it generally gives you 4 settings off, low,medium and hi.
how can we use the potentio metre to control something inside pc like games????like i am trying to make a throttle quadrant of a flight simulator for a game which is installed in my pc.and i saw in vedios that we need a potentio metre for that but it doesnt show how to connect it to pc.so o can you please teach me how to use it controlling something in pc games?
I have a question if some one could help me. c: What potentiometer do I need for a 6 volts 800 milliampere power supply that's going to control a 6 volt motor? :I
thanks, beginner in electronics, hard to find diy for beginners, thank you for your help :) do you know how to adjust amps, can i use it like variable resistor or something?
hello sir... im so amazed but just a follow up question, how about try to use the direct outlet "wallpowered" does this project possible a with a CPU fan and a POT............(newbie)
Has anyone done a video about (How to wire two potentiometers in series?) I have a situation where there is a 1Meg single turn potentiometer. It is TOO difficult to set it with accuracy because it is single turn. I was told that I could increase the accuracy or make it much easier to fine tune if I add a 10k ohm potentiometer that is 10 turn but I need to hook it up in series.. Is anyone up for the challenge? Thank you in advance for your help.
Hi Ana! Actually no. If you want to wire it as a variable resistor, you would only wire two legs of the potentiometer. So let's say you had a small motor, a battery and a potentiometer. From the positive of the battery, run a wire to one of the outside legs of the potentiometer (doesn't matter which one). Run a wire from the negative of the battery directly to the negative of the motor....then run a wire from the center leg of the potentiometer to the positive of the motor. That's it! Hope this helps.
If it has three leads, one is ground, one is for low speed and one is for high speed. Just omit the low speed wire since the potentiometer will adjust it from off to high
yes i did thank u sir i searched for this video and found a lot of crap explanning the physics AND bla bla but not explaining easy and short how to freaking connect this shit and wiring it up thanks again i finished and got all i need at 3:50 xD
Sorry for noob question... But what is difference between varying resistance and voltage...? I thought when u varying resistance its varies voltage? Sorry I'm new to all this stuff :)
+John Smith Varied resistance varies the current. Here, you are varying the voltage by using the voltage reference for the third leg. If you wire all three legs, the voltage of the center tap will be the minmum of the left leg, max of the right leg, 'left' and 'right' is totally subjective here. If you wire only two legs, which requires the center leg plus one of the left or right legs, then it will just function as a variable resistor, which will limit the current output. The voltage can also reduce in this case, but the amount of voltage reduction will be relative to the load, and to the original voltage.
Hello , I really liked your video sir ! 💜💜 Sir , actually I need your help ! sir , I am working on a project where I have to use a suitable potentiometer that can oppose 2 Amperes of D.C current !!! I have 6 A of D.C current and I want to use 4 A of D.C current by stopping 2 Amperes using a potentiometer or anyhow possible ! 6-2 = 4 ( 4 Amperes I want to achieve). Can you please tell me which potentiometer should I use or how can I do that anyway ?
I can't get my simple LED to come on with this setup. but the way i set it up, i can... Setup on bread board: Power source+>jumper>center pole of pot>out through right pole of pot>220ohM>+LED leg>out through -LED leg>jumper to comm of (-)power source. if i vary the comm leg, left/right, i can clockwise increase/decrease resistance depending which side comm is in relation to LED/resistor. i took everything except pot off, set up circuit just like you did (exchanging fan for simple 2 pole little LED and 220 ohm resistor)and triple checked breadboard placement. OR is the low voltage of the LED preventing dimming or even lighting up. VERY new to e-, sorry. i'm trying to build a bench power supply with adjustable volt and amp, thought i had the pot figured out and this video threw a wrinkle wrench in my monkey gears(purposeful misquote).
+patrick holcomb Patrick, the reason your led wouldnt work is because my example used a dc powered fan where polarity is not important. LED's are polarity sensitive.
Hey great job on the video! Could you do a video on how to wire a transformer 120v to 24v with a digital volt and amp gauge with a potentiometer? Or just give me a drawing. I want it to be small like you video. Thanks
Do you need a special potentiometer to use in a 12v 10A to 25A power supply circuit? The sellers rarely give amperage specs on the potentiometer listings. I have a power supply made from a computer PS. I want to make it variable. Seems simple enough. But I do not want to fry my potentiometers or damage other components in the process. I have a bunch of 10k linear pots but I am guessing they might be rated around 3 to 5 A?
OH MY FUCKING GOD THANK YOU SO VERY FUCKING MUCH!!!! i have watched and been reading for 3 hours.....and everyone CONVOLUTES THE HOLY FUCK OUT OF SOMETHING SO SIMPLE THAT IT CONFUSED ME! all i wanted was to turn my xbox power supply into a variable voltage bench Power supply from 0-12v but everyone gose blah blah blah blah blah blah blah theroy theroy ohms ohms turn turn turn..and do little to no real explaining on the wiring process.
I stopped watching when I heard the second beep from the smoke alarm. Please change the battery! You probably did or it died completely and beeps no more. hahah
Best video iv seen so far gets straight to the point.

Great! I'm glad it helped. We've all been there. : )
Thank you for showing the diagram and video of the breadboard. This helped me today to add a potentiometer to the heater fan in my car.

This video works for me. Thanks, I like the idea that you chose to draw a diagram.
Thank you so much for such a basic tutorial. I am a beginner and needed such a video. I now have mastered the potentiometer. Yah!!!
Great Nick! Glad I could help :)
Thank you so much!! You actually made it simple. Every other video says "simple" but it is actually not. This is going to help me alot.
That's great! Glad it helped : )

finally a smarter ans simple tutorial..Thanks my friend..
finally someone made a good tutorial!! thx
At last! This acctually corresponds the search words i entered. It took me 2 hours! Al lthat other channells nonsense got me hatin!
Very good demonstration sir very clear. 😀
Excellent video and explanation 10/10
this is sooo good !!! i was looking for a simple video like you were and you done it !! well done. ha cheers to simple explanations for everyone ! : )
Thank you. You did a good job of explaining for first time user.
there are lots of clips with no explanation and lots of music. I must say they should change...
Great and simple tutorial, keep posting more.

Just what I was after. Many thanks. 👍🇬🇧
Very helpful. Might I ask how do you know what size ohm potentiometer to use? Thanks!!!
Good video if I was just hooking up a pot to a led light with the dimmer leads coming out of it . It has 5 wires I think for a bluetooth capability, how do I figure out what three . I have a 50k pot
how would you go about wiring a potentiometer to an LDR. The LDR has 2 normal wires from it but plugs into a Control PCB board.
Great very simple to understand but can you do a video on using a potentiometer controlling load with variable Amp . Thank you

@Budzilla Thanks for your clear explanation; Also Super important, what kind of marker are you using?? Thanks!!
Great video.
since the negatives are touching... why would it just by pass the pot and if it does then why now just connect the two blacks directly
Thanks a lot....this video helped me alot. thank u so much..
what type of pen ?????????????
I hope you changed the battery in your smoke detector.
I'd rather just rip the piezo buzzer out of it.
was probably using the batt for the tutorial hh
Thought it was one of minw! 😀
how much current can a pot handle
This offended me
too simple

A bread board is simply a quick connect board used for prototyping and temporary circuits :)

Budzilla Sohoski Which setup do you recommend for a CPU fan, and also do you recommend a 10k or 100k? I have access to both so cost isn't an issue!
The way I wired it in the video is how you want to wire a couple fan. A 10k pot will be fine.
Budzilla Sohoski okay thanks
Budzilla Sohoski What if the fan has three leads? (red black yellow)
If it has three leads, one is ground, one is for low speed and one is for high speed. Just omit the low speed wire since the potentiometer will adjust it from off to high

i think i found my video before even watching
wrong. there is a constant drain of power thro' the pot.
I blew mine up and my room smells like smoke
I had the put to much voltage into it
god is that you?
Ha ha! Hope it helped you out. Simplicity is always a great start : )
I stopped watching when I heard the second beep from the smoke alarm. Please change the battery! You probably did or it died completely and beeps no more. hahah
next time do video in something better than 240P
nope smoke detector caught fire and burned to the ground!.
