Does this work with a 9v battery? Because mine doesn't want to work. Am I using too low voltage? I am trying to make a 3v dvd motor run. If I can get that working, I can build my ev longboard
+boowonder888 motors draw quite a bit of current. assuming your motor is OK and properly connected it might be a regular 9v battery is not enough. have you tried with a external power supply?
Great video thanks... nicely paced, clear, understandable, just what I needed. While I was watching it the courier delivered two L298N modules I was waiting for! Guess why I was watching!! :o)
I just watched your video again. Definitely worth while. Very imformative. Im a newbie at this. I'm so so with Electronics..I know the basics but programming and the Arduino are totally new to me. Im going to visit your website to get the details. Thanks for sharing your time and knowledge.
+William Williams Thank you. When I am looking for things like this, I would rather simple to get started learning, than complex and comprehensive. Comprehensive can come later.
With a stepper you will be using digital 4 wires per motor(assuming a 4 wire stepper) so an uno could control 3 and a mega could control 13. But for that many motors there are other options depending upon the size of your motor. There is a A4988 module which only uses 2 pins for each motor. One is for direction and one for steps. These boards can also do 1/6th microsteps so very nice feature there. The A4988 is pretty much equally rated capacity-wise if you put a little heatsink on it along with paying attention to cooling. So with the A4988 you would halve the wires used and in theory double the number of motors under control.
I'm testing this module which I bought last week...its unable to turn even the smallest motor (thumb size)...it just changes its hum. I don't know...Solution it needs a 12 volt power supply and a 5 volt at the same time.
very good explanation , clear voice , nice graphic quality ! thank you for all of that ! :) can you just explain more the idea about the capacitor , i'm trying to make a 12 V motor work on Low RPM ... thank you again :)
Thank you very much bro! Your videos are great and very clean, thank you for sharing. I have a question. What is the formula or method to determine the capacitor to smooth the modulation as you said at the end of the video? Thankkk youuuu!
Thank you very much for this video..nice explanation! I would like to ask you: why do we need to connect the common ground from the L298N to Arduino GRD pin since you are powering arduino with USB? I tried it with no common ground and the motor doesn't work...why? This would really help me to clear a few things in my mind..
I like the simple way that you explain this, May I ask you, I have seen lots of people feeding the power output of a motor "Out of a cheap servo.. on to the H-Bridge.. so my question is, Can one feed the signal directly out of the receiver on to the H-Bridge and bypass the servo pc board?
Great video! I have a question. Can you use pwm on two motors connected to the L298N simultaneously. Could i have one motor doing it's thing and another doing it's thing, or will they both rely on the same pwm?
Awesome tutorial. Totally understood. Thank you. How can I revise the code if I want to control the dc motor for only 3 seconds forward as I supply the required voltage and as soon as I stop supplying that voltage, this time 3 seconds reverse? Just like a park assist of a side mirror of a car. With reverse gear side mirros will move down for 3 seconds and with forward gear it will move back 3 seconds to its starting position. Maybe the scenario might be enriched.
Can you address, this issue that usually you need some sensing to start the motor in a specific direction (I am thinking of the 3 phase coil setups in for example ex electric bikes, aka "push to start when you do not have the hall sensors). Any comment on this ?, thanks in advance
Can I connect four dc motors if I want them to spin only forwards? and one at the time. I mean each OUT from the driver to one wire of the motor, and just wiring all the gnd's together.
Thanks you for such a nice video. If you had some time to spare I'd like to ask: How would I design a controller that does the following to a 2.5 to 3 rpm D.C. Motor, 4W, 11V: run clockwise for 2 minutes, pause for 2 minutes, run counter clock wise for 2 minute, pause and repeat. The other modes of operation would be clockwise only - as in, 2 minutes rotate clockwise, pause 2 minutes, repeat. Same thing for the counterclockwise scenario. Thanks in advance!
Hi can you help explain how I would go about choosing the capacitor mentioned at the end of the video to smooth out the PWM voltage? I am trying to make my DC motor operate at a very low RPM, but when I decrease the pulse width, it whines and wont turn (as shown in your video).
I have not done this but I can put you near the answer. RC = Time in seconds. Therefore C = T/R where R is in ohms and C is in Farads, not microfarads. Plug in the time length of the ON pulse width and probably divide that by 2 or 3 so as to not flatten the entire width, and calculate R to be the voltage divided by the current drain through the motor. That R=volts/amps is not actually the DC resistance because motors are inductive, not resistors, but also measure the DC resistance of the winding anyway to approximate R in a second way and see if those two Rs are close. That will give you a starting idea of farads (example: 0.1s/2 divided by 50 ohms = 0.001 farads = 1000mF). You see capacitor size depends on how much current the motor draws and the pulse width; the smaller motor and smaller pulse width means the smaller the capacitor. I would experiment with values around that kind of calculation. To be more precise maybe you can measure inductance of your motor winding and plug that in for R using a reactance and frequency equation. But I think instead do this by experimentation after you get close with the easier estimate. You need diodes to flatten the flyback current of a motor; L298N spec sheet shows them. What about the polarity of a capacitor? AC capacitor, not DC electrolytic.
Thank you so much! Here with a new robot project for beginners, so it helped a lot! Just wondering how to do it with the arduino not connected to the PC. Thank's!
+Albert Borràs Pons Sorry for the delay. I suspect you figured this one out. There are a huge variety of ways to get power to the arduino once you have programmed it but one of the easiest is to buy a 5v USB battery pack and just plug the Arduino into that. One of those tiny cigarette lighter sized packs will power an arduino for pretty much forever. If you are using this LN298N then you can tap the 5v and the GND on this module to run into the VIN and GND to send power to the arduino. This module is excellent for robotics projects.
+3D Printwiz With a DC motor, holding position is tricky. With a servo motor is is very easy, and with a stepper mostly easier. The key is that if you are putting power into a DC motor it will usually move. Thus to hold it in position would require that you are only putting enough power into the motor to prevent it from being forced in a different direction or to rapidly move it back to the desired position so rapidly that it appears still. Thus the first step is to identify that your motor is being moved. The easiest (but not only way) would be some kind of sensor that detects either movement or position of the DC motor. So effectively what you would end up doing is creating some kind of feedback to compensate for the movement of the motor. What you would be doing is to recreating a servo motor; which is a DC motor with a sensor and positional feedback. Thus the answer is probably to use a servo motor. There are servo motors that can rotate 360 degrees although most commodity servos are limited to around 180 degrees of motion.
Dear great teacher, I really need a help from you,I'm trying to figure out if it's possible to make some servo motors by using some Rotary encoders from an old ball mouse or from an old printer and a car wiper motor to use in a cnc project. I've seen homefaciens doing it but i really really don't understand a thing he is saying. Due to your charisma of explaining everything so well I beg you to help me in this matter.
I have 2 motors coming out of each set of outputs of the chip (4 motors total). One side doesn't seem to accelerate as quickly as the other using the PWM. One side of the vehicle starts at the correct speed while the other side takes a while to get up to that speed. Do you know what could be causing this issue?
thank you sir, i find it very useful. i can understand the concept, im still new with these stuffs. you explained this well but sir, for the codes, why did you use "analogwrite" meanwhile its in digital pin? i still cant get it
Do you know is it possible to control not speed but position (angle) with this driver from arduino? Lets say i would like to turn 10 degrees from current position clock wise or 15 counter clock wise? If so, could you do the demo please? Thanks
Help, how can I synchronise two dc motors. I am building a biped and each leg is a windscreen motor, I want to make sure the left motor does not get out of step position with the right leg. Any ideas gratefully received.
do i have to upload the code after making the connections or can i make the connections later?.. and can you please do a video on how to control 2 motors with bluetooth using arduino uno?
How would you modify the code to make the motor spin in one direction at a controlled speed? My son has a science project of Mars and I would like to make it rotate at a slow rate.
I always fold the exposed metal over the cable and clamp them both in. Then I don't need to worry about it coming loose later because it's not gripping that very thin cable.
thanks for the video but i have a problem my motors run without the the l298n driver but i connect them to the driver they don't rub anymore and yet my code is very ok what could be the problem
Thanks for making this helpful tutorial. I got one question; what is the point of having a common ground with the arduino since the arduino has its own power supply from the USB?
+brusk qadir A common ground is generally how electronic work. The main occasion where you isolate things is when those things might be naughty and feed current back through the ground. This common ground is so standard that you will find many circuit diagrams that don't actually show the entirety of the wiring style circuit but every time something goes to the common ground there will be a line terminating at the GND symbol even though all of those grounds are actually connected. Check out many circuit boards. They will do all kinds of things such as a ground plane and whatnot where the ground sort of makes up a huge proportion of the board's copper. When looking at a circuit board that is usually the giveaway that you are looking at the ground, it connects to pretty much everything.
Is it possible to have your computer USB connected to the arduino to read from the serial monitor While the L298N is hooked up to the arduino and the motors actively running.
My motor driver l298n is burning when connecting 12v 1.3 ah lead acid battery directly..! How to fix? Will using a mt3608 dc dc step up will work? So that I can reduce the current from battery.! Please help.!
hi Im using this driver to control cd rom microstepper motor with arduino. motor indicates 4-9v and 500mA current. Even though the code works correctly and motor is functioning, motor is heating very much in few seconds. can you tell me what could be the reason?
Hi, thank you so much for the tutorial, it really clears things up in terms of what goes where on a motor controler. Just one question, since the L298N can be powered by a 12 volt power supply can it have an output voltage of 12 volts right to a motor or is there a limited voltage it can output. Sorry if the answer is really obvious I'm new to the whole motor control and arduino world.
+TangoBravoCheesecake It can actually take in about 35v at two amps per motor. But those numbers are the theoretical maximum. Generally you don't want to run right up against the maximum. With motors I like to stay as low as 50% of rated maximum and start getting uncomfortable if it is going to sustain anything over 80% of rated maximum. Also there are slight losses which you can check the charts for but experimentation is usually easier. These losses mean that if you put in 15 volts that you won't quite get 15volts going to the motor; maybe 13.5? The same goes with the part that can feed back 5volts to your arduino. If you don't put in around at least 7 volts into the controller then it can't put 5volts back out. I have never tried it but I suspect at very low voltages much below 5volts that the L298N would just not work properly. At those low voltages there are alternatives that would probably be cheaper and work better. If you need to go beyond the specs of this module there are other modules that pretty much work identically yet can handle far larger loads. For about $10 you can start to crack 50 amps. The key to this module is that it generally can control most motors that people are using for homebrew robotics type projects and is really cheap for what you get. Good luck.
Very nice video. could you explain how to add trigger and countdown timer in this dc motor controller. I want to make a motor work by trigger (water level sensor) and will be stop after lets say 10 second. Can we only add some code? thanks
Thank you so much for the video! It clearly explains what the L298N module does. Could I quickly ask, what is the benefit you get over using this L298N module as oppose to just using a L298 chip and wiring everything manually? Does this module simply offer convenience or is there something more? Again, thanks for being so informative and clear! Regards.
the ln298n controls higher current/voltage. you shouldnt be able to ffeed 12v into the motor directly from arduino with higher current. So this module is required.
Perfect. Learned in 10 minutes what I've been trying to figure out all week(plus I smoked one L298n). Thanks.
this was so incredibly helpful.
I'm a super beginner and you explain things very plainly.
thank you hahah
You can use this circuit as well, this is a powerful 30A design: th-cam.com/video/9UVxvpHyqMI/w-d-xo.html

Can I control motor direction with a pot as position sensor, I think the wiper would go to an analogue pin on Arduino. Can you advise, please.

is it possible to use this setup to control a micro dc motor in a way that it would only turn 180 degrees then go back in a loop?
How do you calculate the proper-size capacitor to attach to the circuit to allow the motor to run at small PWM signals?
Nice 👍. Can you make a video for larger motors pl ?! I mean of the motors with stepper or servo with drives . Thx for this video 🙏
Do you know is it possible to control not speed but position (angle) with this driver from arduino? Lets say i would like to turn 10 degrees from current position clock wise or 15 counter clock wise? If so, could you do the demo please?

what wires are you connecting to the L298N? are they female connectors on the wire end?
Where should I place the capacitor? I have two dc motors .. should it by o the line from H bridge to the motor? One capacitor for each motor?

Very nice video. could you explain how to add trigger and countdown timer in this dc motor controller. I want to make a motor work by trigger (water level sensor) and will be stop after lets say 10 second. Can we only add some code? thanks
hi can we control the motor, if arduino is connected to a ultrasonic sensor that is motor has to stop if obstacle is below 15cms
I have a question how to use mq 9 sensor detect the gas,then the dc motor moves. Do you know how to coding like that? Pls Help Me
could this also work for changing the polarity on an electromagnet?
Thank you so much for the video! It clearly explains what the L298N module does. Could I quickly ask, what is the benefit you get over using this L298N module as oppose to just using a L298 chip and wiring everything manually? Does this module simply offer convenience or is there something more? Again, thanks for being so informative and clear! Regards.
the ln298n controls higher current/voltage. you shouldnt be able to ffeed 12v into the motor directly from arduino with higher current. So this module is required.
Now Controll anything in adrunio via keyboard{makeAnyprojects}

what is the name of the wire you used to connect to ENB? Please let me know as soon as you can! I have a deadline next week. Thank you
hello .. i want to use 6 motors of 12 volt and 60 rpm so it is possible to run 6 motors using this motor controller ?
