    Thank you for showing the wiring of the mosfet clearly on the breadboard, and the details of the shared grounding. I wasn't sharing the ground properly, but now I have got the temperature control working, thanks to this video (and it is the fourth that I have watched looking for enlightenment). I am using a k-thermocouple and an LCD display but the mosfet circuit is the same.

    Bro this worked like a charm. Using this to pull in cool air into my electrical enclosure for my mobile solar panel kit to prevent a greenhouse affect. This is super useful because it will only use power when necessary to cool the enclosure what with the PWM and being able to set the desired temp. Thanks so much for this great video. This was basically the first time I was able to successfully make something work with the Arduino other than turn on an LED lol.

    Thank you, exactly what I needed.
    Also interesting you used a voltage divider on the A0 pin, that is a nice touch with the R1, cheaper than the TMPs used in many other applications.
    Additionally, 12V is probably better than Mains, so this is a relatively safe project.

    Thank you much. Great video, clear and clean. Much simpler than I expected. I need to choose a mosfet that will handle a 2 amp 200cfm 12vdc fan. My only trick now is how to mount the thermistor to my RF amp heatsink. I think I will give this a try. I was just going to switch the fan on using a relay and some op amp temp circuit, but the pwm capability of the Arduino is just too cool not to try. Take care :)

    What the heck is up dude! (I laughed alot of your intro! Lol)
    Would it be possible to replace the temp sensor with a potentiometer? So i can control the speed up and down how i want?
    And i guess its possible to read the RPM, and "print" it to a display or something?
    Im figuring out how i can make a fan controller that shows fan rpm and can control pwm fans (for testing only, not to use in a computer or such things)
    I just want to be able to turn it up to full blast etc.

  • @carlch8907
    @carlch8907 11 หลายเดือนก่อน +2

    There's an observation about that gate drive...
    Whenever you are PWM switching an inductive load (i.e. like that fan), without a gate resistor, there's a good chance that gate is going to ring (oscillate), that might cause electrical noise issues that could interfere with other circuits, including parts of the microprocessor, especially if you are making that microprocessor to multitask. It happened to me with some serial data I was using, it looked all erratic and did not know where it came from until I hooked up a scope to the power supply line, you could see all kind of noise along...
    At first I thought the freewheel diode alone and the decoupling capacitor would eliminate good part of the noise, but it did not. The gate resistor was the saver here...

    Genuine question: would it not be easier to simply use a 4-wire PWM fan and control it directly via your PWM output pin, rather than driving a Non-PWM fan via a MOSFET?

  • @grinerpolevault
    @grinerpolevault 4 ปีที่แล้ว

    This was an very helpful video, thanks so much!
    Question that you or perhaps another viewer could answer - Can I control the fan speed using a PWM signal sent to a MOSFET (such as a IRFLZ44n) or does the MOSFET only act as an "On/Off" switch that is controled by the PWM? Thanks.

    • @lamjeri
      @lamjeri 4 ปีที่แล้ว +1

      In short, yes, you can use the IRFLZ44n to PWM controll a fan.
      Both of your questions together are a bit puzzling though. You can control the fan speed by using the MOSFET you said and the MOSFET does only act as an On/Off switch.
      PWM signal has a duty cycle and a frequency. Frequency of 1Hz (unreal, only for demonstration purposes) says that the signal repeats every second ( Time period = 1/frequency ). And duty cycle of 75% says that during this 1s time interval, the device will be on for 0,75s and off for 0,25s. You can make a PWM signal by simply switching power on and off by hand (nice way to test it). It works ok for a fan, but light sources, need much greater frequency.

  • @Kntryhart
    @Kntryhart 5 ปีที่แล้ว

    The Arduino Uno specs are 40 mA per pin other than 5V and GND, 200 mA total (other than 5V and DNG), 1 A max through 5V and GND. So if the motor draw more than 1A, the ground, of the Arduino, may be unable to sink that current?

    what am i missing here... i can get the thing to work with a transistor and 12v fan and a separate power supply for the fan. but i want to run the entire thing from a bank of 12v batteries that run my beehouse/hives etc. this is to turn on small fans to extract humidity from each hive in the winter when they're all insulated up. obviously i already have the stepdowns to go from 12 to 5vdc, but i just can't noodle the wiring for the 5vdc fan... it should be easier right? just set the value of the fan speed based on the output of the sensor pin, and.... and... that's the part i don't seem to get. if i just make two spliced wires so the 5vdc goes to the sensor and the fan, clearly it will run forever without the logic. so it has to go in and out of either the nano (want to keep everything small and cheap - multiple hives)

    Hi, can I use the same 5V pin from Arduino (the one that goes to MOSFETs gate) for fan powering (instead +12V in diagram, see scheme at 0:44 in video)? In other words, the 5V Arduino pin will be connected to MOSFET gate, MOSFET drain will be connected to negative fan wire, positive fan wire will be connected to 5V Arduino pin. Could this work or (i) should I include 10k resistor between 5V pin and MOSFET or (ii) should I use lower voltage 3.3V pin of Arduino to connect positive fan wire and sacrifice a bit of small 5V fan speed..??

    Jacob - I am totally new to Arduino but something struck me and I am curious to ask you. Why do you use the PWM output of the Arduino rather than an analogue out to provide you with the 0-5v into the MOSFET? Would the fan be better controlled with an analogue 0-5v signal to control the 0-12v supply circuit?

    • @jacobdykstra8499
      @jacobdykstra8499  7 ปีที่แล้ว +1

      John Burns analog out on arduino is not true analog, it is pwm. It can be filtered into analog voltages but mosfets are really good with all the way on or off states and not in between. most likely the mosfet will latch into the full on state once the threshold voltage is reached.

    • @jacobdykstra8499
      @jacobdykstra8499  6 ปีที่แล้ว

      Rodney Yrureta according to the datasheet the maximum gate threshold voltage for a 2n7000 is 3v so yes 3.3 should trigger the gate but it is pretty close, however, 3v is the max so it should be fine. The transistor does not heat up much under normal operation. It is a switching transistor so the voltage drop across it is pretty low. It should remain cool switching any current less than its 500mA pulsed rating.

    • @jacobdykstra8499
      @jacobdykstra8499  7 ปีที่แล้ว

      It's good practice yes but the benefit in this particular case would not be there because brushless dc fans already have them built in their driver circuitry. Also it is very common for mosfets to have some sort of reversed biased diode there for back emf. If the fan was not a brushless fan with its own driver circuitry then yes a diode should be used. It won't hurt to add the diode but with these fans there is no benefit.

    I have few questions:
    1) if you are to use 5V fan, do you need to modify resistor values and if yes, what values should they be?
    2) as I understand it, the type of transistor depends upon the voltage that I use to speed up the fan, and which one would I use for my case of 5V-fan?
    I would be really thankfull if someone answered me because I'm having this as my project and I can't find this information anywhere.

      1) no.
      The resistors are only used to read a sensor value.
      But when using a 12V Fan you might need a bigger Mosfet or transistor
      2)you can use almost any type of Mosfet e.g. the IRLB8743PBF but the Gate Threshold Voltage shouldnt be too big (2-4V)

    Would the temperature sensor drain a 12 volt battery?

    Hey brother can you tell me the code for my project . ds18b20 temperature sensor , LCD 16×2 , arduino UNO & fan , all connected .
    As the temperature rises , fan goes fast or Start rotating and if temperature goes low , fan slows or stops down...

    My fan only works well when the PWM signal is at 255 and at every value below that it rattles and gets really slow. Below 200 it barely even moves anymore. Does anybody have a solution for that?

    Hi there
    I would interested in buying a project like this! It's possible to buy from where?
    I have a garage and I will use a car battery ans 2 computer fans and I woudl like to connect with this board because I have a damp effect inside 😦
    Thank you

    Intel's PWM fan startup limit was, I think ~30%

    is it possible to set 3 points in pwm?
    i would like to set my fan in low med and high speed. Is there anyone who knows how? thank you in advance
