On behalf of all mechanical engineering students, thank you so much for breaking this process down into something we can understand!
I really love your enthusiasm. You're getting better and better. As a viewer right from your first few videos it's amazing to see your progress. Keep on!
The heating element can be represented by a first-order transfer function if you apply a step input (e.g 5 V or 12 V or whatever the supply voltage is). Plot the transient behaviour as the temperature raises and settles about a value (sample at regular intervals though). This will fit the equation K/(s(tau)+1). K is the gain so that will be the maximum temperature of the plot. Tau is the time constant and this will be the time it takes for the element to reach about 63% of its maximum temperature. You can either simulate this in Simulink and play with the PID values (make sure you use the z-domain rather than the s-domain though.
If you don't want to use simulink then just use a tuning method like ziegler nichols
One of the best PID explanations I've seen. You are an excellent educator. Thanks!
Going to make some rosin with this info? lol

cant wait to see the recycling extruder project. Thank you! Amazing project!
Thanks for all the time and effort you put in to this video, very well explained!
This might be the basis for a new barbecue controller project. Thanks for the effort in making such a clear and complete tutorial.
man you have one of the best electronics projects channel on TH-cam!!!
good job!
Siento que la calidad de los vídeos es cada vez mejor, felicitaciones, como siempre increíble.
Great explanation! I'm what you could call a beginner in grade 10 at school but I've picked up on the basics really quickly and have decided to do a project for in the house. I am going to use a PID to control the temperature for an espresso machine. This explanation was really useful, but still alot of research to do!
This is incredible. I am an MD doing research in neuroscience trying to make an in-line heater for live-cell imaging. This video is exactly what I needed. absolutely stunning!!! :D :D
How did it work out?
Great job. Everyone else is launching rockets and having us use PID for telemetry. Thanks for simplifying it and making it accessible.
SO HELPFUL! Learning so much from your explanations through the code and each piece of electronic, thank you so much
This is what I have been looking for my pastry proofer. Thank you very much Sir.
Thank you so much for sharing Sir . I am trying to make my own soldering station by myself recently.
Really nice, man! Great job! 😊
I've been trying to do a PID with Arduino for Sous Vide cooking. The tuning of the PID is the most difficult process for me. The key is to have the patience and good data collection to adjust the various parameters correctly. I tried to doo it with a Crock Pot but there isn't any circulation in a crock pot and I couldn't get the temp deviations down to an acceptable level..
Very good video with good starter information.
Can you share your thoughts about how you brought the temperature deviations down to an acceptable level?
Ahh... How nice with a video without JLC commercials! ;)
I made my machine learning pid iron station and i made pid code by helping your videos great man
And mad pid line follower 🙂❤👌pidth-cam.com/video/NwuY7qbs2Dkl/w-d-xo.htmlinefollowerpid
Great video. You inspired me to build a fan for my smoker to control temps for long cooks.
this is litterely what i needed for a school project and this helped a lot
I haven't even watched the video and I gave you a Thumbs Up. I hope this is exactly what I need to control my burnout oven.
Very nice and clear! You set a high standard.Thanks!
Great informative video, very nicely and deeply explained about each and every aspect of PID controller's functionality using Arduino. You are great explainer, this skill of yours will educate needy learners.
It's excelent! Best explanation I've seen as well. Thank you so much!!!
Amazing work !!!!! thank you for your effort and passion !!!
Guys why is it that there is a diode on the protoboard for the part that controls the heater ? i dont see it in schematic (min 6:52). Truly one the greatest PID explanations on youtube! Thanks you guys! Keep at it!! :D
Exelente control pid lo usaré para modificar un horno para soldar smd ojalá lo hubieras hecho en español
Brilliant this is what I was looking for
Thank you very much
well done, I like the way you did not use libs but wrote the code yourself, it is easier to see what you are doing.
Nice explanation of how PID works. Keep up the good work! - Btw. is that soldering iron only 24 Watts? I would think it would be 40 or 50 watts by looking at the size.
the best explanations ever, thank you for the detail
Appreciate you efforts. much easy for students . Thank you
A great presentation. congratulations on a real contribution to education.
On process control
Thanks to you because those subject to handle to you.I am using hakko 907 temperature control iron (clone).your nest video very useful for me and my temperature control iron 907.Thanks
eres genial. gracias por tu aporte, estuve buscando esto durante mucho tiempo.
Exactly what I was looking for! A+ Teacher!!!!
Thank you for sharing! I learned a lot.
I can easily understand your english, it’s very good
Thinx for your amazing video
Great explanation, easy to understand..
No PID filtering this time ha..... Am just kidding.I really enjoy your tutorials.Thanks a lot.
May need elaboration for more advanced engineers on the thermocouple. They DO NOT put out a voltage based on temperature. They work on a difference in temperature between a hot junction and a cold junction. The example video is OK for an elevated temperature in a temperature stable room, but would not work to control the temperature of the room because the cold and hot junctions would be at the same temperature. Great introduction, and a good place for more advanced students to learn about the hot and cold junctions and temperature measurement of the cold junction to get accurate values for the hot junction. The more advanced students and engineers can locate the cold junction in this example.
Very good video...easy and concise
Very useful and understable video .. Thank you very much for your effort
really helpful for Mechatronics engineers
Super awesome presentation thanks!
Awesome work, thank you for sharing the code! I have numerous arduino projects I have waned to complete involving PID control but could not find any PID code.
Thank you for your good explanation !
Nice work! Just saying.. most of those industrial PID has also option to control solid state relay with PWM, so it will work flawlessly with any resistive heating element...
hi..
thank you for the good explanation about the PID .... it seems there is a 2 degree difference ( higher ) then the set temp...
now im analyse where this offset comes from.
Hi dear sir please kindly share which model nano Oscilloscope you use ... if its possible please share the link of that Oscilloscope which you use
Amazing quality!
You never disappoint.
Liked and subscribed! Great job
gracias por tu video, quisiera preguntarte, necesito controlar la temperatura de una resistencia industrial para un proyecto ¿que pwm puedo usar? ya que la resistencia va conectada a AC!
excellent videos!!! more of it please!!
Great tutorial Man....!
Im Waiting other great video...
excellent explanation man!
Hey dude!
I have a question, I a want to use a timer of 15 minutes for hold the temperature of 121 C°, after these time I want put the element heating off, how can do it?
nice nice nice, youre a real maker and im a fan:D
hey one question, is mosfet or triac the best control signal amplifier ?
or do you have a list of another choices?
may i ask why did you use -3 and +3 range in the integral part?
Andwhat would happen if we use bigger range or smaller range?
Thank you very much dude, I really appreciate this video ♥ please can you make a video about a line follower with PID
Nice video, thanks for sharing :)
If I am using two of the same heaters in this videos could I used the average of the the two for the PID portion of the code? Essentially I am try to heat up one item in a sandwich style configuration with one heater on top and the other on the bottom.
With such explanations,
Please make tutorials on controlling a stepper motor using arduino, as I want to open/ close a box's window depending on the temperature inside a box.

Good Video. Is there a way to calculate accurate P,I & D variables instead of hit and trial method?
I like this video.
From many years of experience i will advise you to have a function on your coming
soldering station controller, where it enters sleep mode, reducing temperature when not being active
soldering.
This is due to the fact that soldering tips are " burning out ", when standing idle with high temperature.
Also the nickel layer is thin, especially on the chinese iron tips you are going to use as per your video..
Kind rgds.
niels larsen.
A lot of the burning of tips is due to the fact these soldering irons do *not* have a temperature controller.
In order to not be too cold when they are working (touching new cold wire and melting tin) they are getting slightly too much power.
Basically, in rest the temperature goes up because nothing cools it down.
I agree it is a nice feature to add.
good job, congrats
Thank you!!! This is really great!!!!!!!!!!
excellent video.
Hi, Excellent study, clear explanation. thanks for sharing. I have a question. I wanted to control the 220V AC heater with SSR. I tried to do but I couldn't drive SSR with PWM. and Is banana required for the circuit? :)
Great video. About how long would it take to boil 4 cups of water using this?
Hi There. Do you know if its possible to use a thermometer that communicates over I2C with the standard PID libraries?
Hello! Excellent video. What accuracy can we attain using this given room temperature conditions? Is 0.1 degree C doable?
Hi there, in your code what's the meaning of PCMSK0 scan? and is there significance of the PWM frequency being roughly 1000 Hz? thanks
I need to do this exact thing but it must be much smaller, can you recommend smaller products to create this same type of PID heater control?
Hi for building soldering iron + hot air gun do i need the MAX6675 or can i build it without it ?
My understanding is that the PWM should vary the voltage going to the ceramic heater? Is that right? Or does it just switch it on and off quickly using the PWM duty cycle to vary it? I'm finding my heater is always getting full voltage and doesn't shut off. Your circuit diagram is different to what you show in the vid as there is an extra component there - is this what I am missing? Any idea why my heater isn't shutting off, even when the PID value says it should be. I'm replicating this on a raspberry pi but other than that the heating circuit is the same as your diagram as far as I can tell. I'm assuming the red lines you have marked 12V are the positive 12V supply and the rest go to ground. I'm driving the BJT with a PWM signal and using the PID_value to change the duty cycle of the PWM.
Excellent video, one thing I haven't grasped clearly is the conversion between units in the code: if I read a temperature value in say celcius from the sensor feedback, and output a current value (0-2.5 A) to the hardware that drives the process; how do I convert between the two units?
if I use that encoader module then those 10k resistor won't required which showed in schematic right?
What did you use for the 12V power supply for the heaters?
@Electronoobs can you explain why you decided to use a BJT to activate the MOSFET? I'm a novice when it comes to electronics, so I'm not saying you're wrong, I'm just curious what purpose it serves.
can you other video that controlls the blower that gives wind to the fire on the burner with this application?
Wohooo, I predicted it! ;)
is it possible to use two inputs for setting PID for example temperature and humidity as inputs?
Could you explain how you adjust each parameter? Do you simply adjust the P constant until the desired ramp up speed to temperature is reached for example? Once you have that determined, the D value then becomes the error constant and need to find the happy medium for that (i.e it lands on the right value and doesn't take too long to reach final value)?
Thanks man.
So PID control(er) stablized something, in this case it's temp(heat...)
Interestin' probably now I know the concept behind STAC
Very nice Video! I've got one question. Is it possible to use a Mosfet Modul (D4184) instead of the Mosfet in your Video?
Estoy llevando un curso de control clásico y me gustaría saber como hiciste el análisis en lazo cerrado del sistema para que pudieras generar el controlador digital, saludos.
Well done, thank you.
Hi Mate, I was wondering if it would be possible to modify the code and schematic to include an output when the heater gets up to the required temp. Sadly I am not clever enough to be able to modify the the code. I plan on using this to control the heater temperature in a scrap 3D printer filament recycler..
dear.... you are a treasure....keep it up..
think very much , very useful video for prctice project
Hi Electronoobs, Thanks for this excellent tutorial/demo. I have a question though - At 7:46 in your video there are several parts of the wiring that are not in your final schematic. It looks like you've added a diode on the "source" side of the Mosfet (is this connecting source to gate??, but I also see you have a negative (black) jumper looped behind the mosfet - what is that connecting to? I can't see what pin you've connected this to because the mosfet is in the way.
I would also love to know this. Have you figured it out?? Would appreciate some info if you had! :D
WOW!! Really nice !! Hmmm, what other heating element i can used? my project is to heat water and maintain its temperature.
Its very helpfull...
do you have any idea if the heater used is operating with AC current and controlled by arduino ?
Is it okay to use a motor driver like l298n for the heating element or the mosfet is better?, I tried with l298n but it seems to get pretty hot so I stopped it because it may burn out
