Controlling DC Motors with the L298N H Bridge and Arduino

@@Dronebotworkshop hi sorry for sudden ask but what is the required(max and minimum if there is such) for L298N H Dual Bridge? i tried to use my laptop/USB Port to connect in arduino but its not running. so far i dont have battery to test it. my code seems correct anyway but it is still not running so i figured the source power is at fault...i might also fry my arduino if i just randomly run voltages which is risky to replace + we are in pandemic and i cant easily go outside.

I liked this project. I'm working as an English teacher in Moscow and some 12 to 16 y.os have no interest in learning English. Then neither did I at that age. Some of them are very bright and they start getting physics in school at about 13 So I want to teach them how to build a whole series of simple electric motors. This will be the perfect way to introduce them to the Arduino!!!

[@Dronebotworkshop]

Hi Robert, I think that's wonderful! Teenagers can be so creative if they are just given the opportunity. Best of luck with your teaching!

[@TexasStatesman]

Your videos are outstanding and greatly appreciated, especially to a newbie like me. My original intent was to build the robot following your “Build a Robot” series but up to video #5 I realized it was somewhat more than I could do, so I’ve opted to learn and build from your individual robot videos (baby steps). I am familiar with ac electrical power which helps when working with dc. I’ve built a few of your examples, following the instructions, including all on this video, using the Arduino and motor controller and none of them functioned initially. Reading the comments from your other followers made me believe it was something I was doing wrong. I purchased all the same equipment and followed your instructions (I think). But this actually turned out to be a blessing. I was forced to read and learn about Arduinos, motors, motor controllers, etc. and not just piece pieces of equipment together and copy code. For instance, in this video with regards to using a joystick. Following your instructions, I was able to get motor B to turn in one direction, nothing else. Moving the enable pin for motor A to #2 on the Arduino and the data pins to #6 and 7, then updating the code, everything is functioning fine. Having to make these adjustments I hope is not a result of me doing something incorrectly as far as your instructions. (Maybe the equipment is not created equal?)

[@dollynhoseuamiguinho5030]

Sorry for any mistakes in my English, it's currently 3:20 am, insomnia hitting hard... It's funny to say that in this project I was reaching the maximum memory size of the ESP32, and as I couldn't find any Bluetooth library that didn't use so much memory, I ended up using another ESP32 with UART communication between the microcontrollers, one of the ESP32 contained the Bluetooth commands and the other read the commands and sent them to the Dashboards using the MQTT protocol. It is important to say that, in the end, I found the NimBLE library with a great Professor and IOT Wizard and corrected this, leaving only 1 ESP32. I'm happy to share this experience with anyone reading here.

[@sandro6691]

This is my favorite Arduino channel. Thank you from Australia.

[@RegisMichelLeclerc]

Personally, I prefer soldering my DIP components myself, but that's just a matter of taste. Sometimes I'm lazy and just plug a Nano. map() is overkill when converting a 1024 values range into a 256 values range, "div 4" is not as bad, but still excessive, and [0-1023] is definitely a multiple of [0-255]. The shortest way of dividing by 4 (integer division) is simply to shift the bits right by 2 positions (shr 2, or >>2). Also, you prefer using 511 as the middle of the interval [0-1023] because it's the end of the first half of the interval, not 512 which is the "0" of the second half. But as you say, the joystick's center is not that precise, you don't care too much. How about a "center" function? The test for the joystick position ("margin") is pointless, because you also have a test for minimum speed before sending the analogWrite() commands, so you're basically doing twice the same thing. The command from the joystick EITHER changes direction OR goes forward or backwards. Not very practical... Therefore, you only want shr 1 (a shorthand for div 2), and subtract 256 to it, giving you 2 values (H and V) in the interval [-256 ; +255]. A test on bit 15 (shr 15 gives 1 for negative numbers) gives the sign in each direction (the 10-bit [0-1023] value is converted into a 16 bit value when you store it into an int) so it's pretty easy to get the direction to send into the H-bridge without cascading the if()s. Anyway, if() is just a waste of resources when you can use a and(0xff) to force a [0;255] range. Also, on demo2(), a linear for() loop with a constant delay is definitely not right for an acceleration or deceleration, that's simple physics. You wouldn't do that in the real world. I know, on such a "project", you have used only a tiny part of the memory for code and variables, you don't care too much about code speed anyway, thus all of the above may sound excessive ranting, but the goal is to get proper techniques rather than trying to find the quickest way to build an example application, right?

[@shahidilhan3139]

why do you need a motor driver?

[@Dronebotworkshop]

Not sure I understand what you are asking here? Are you asking why I personally would need a motor driver board (answer - to build robots) or why one would need one in general (answer - to control two DC motors using the TTL logic level signals from a microcontroller or other logic device). Your avatar indicates that you are a programmer so I'm not sure what you don't understand here. Please let me know so I can assist you further.

[@AndersJackson]

You need one driver, as the Arduino output pins can't provide enough current to drive a motor. If you try get to much current from or into a port, you will destroy the port and maybe even the Arduino. You have to check, but the Arduino have a maximum output current on each board and a maximum sum of all ports. So you are not allowed to go over both limits. There are also problems driving a motot, which a driver also fix, like the motor can generat to much short spikes of higher voltage, which also will ruin you Arduino port, and posible the Arduino. A ruin Arduino can be fixed by changing the processor chip.

I think what genuinely matters is the knowledge to be understood, that is what is crucial, you can be bombarded with so much technical jargon, and end up having no real understanding of what you are involved in. I think that watching valuable videos, which have a concrete outcome are essential to draw skill and understanding from. But also being attentive, focused and taking important notes, when watching videos, and above all OBSERVATION of what is one doing when engaged in electronic arduino projects. And self taught commitment to grow/learn and become a competent builder of electronic arduino projects. By reading diagrams, books, practical experimentations.

Thanks for this video. I actually miss the PCB diagram. You can find the datasheet for the chip, L298N. Questions: 1) Do the PCB have free wheeling diodes for the outputs? 2) I am a bit confused regarding current sense of the module. If you like to measure current, do the jumpers connects to ground? Do you need to apply an external shunt resistor at the jumpers position? 3) If you got some other way of controlling the H-bridge, I guess it will be in order to use In1 and In2 with individual PWM signals and have EnA constantly high.

I don't get why this video only has 20000 views, this is extremely useful for beginners who want to build robots. It is very clear, you made the demo step by step so it is very easy to understand, I think even for people who have never done this before. Thank you so much!! I have a question. What if you have to use a power supply with let's say 300 Watts to power stronger motors?

[@Dronebotworkshop]

Glad you enjoyed the video, thanks for your kind words. The L298N is rated to a maximum of 50 volts at 3 amps per channel (2.5 amps if you are using PWM), so 300 watts is about the maximum for two channels that it could handle. Of course the motor will only draw the current it requires. Personally though I would never un it that close to maximum specs, I like stuff to run relatively cool if it can. If I had to control a really big motor I'd look for other H-Bridges or even build one from scratch with power transistors. The L298N is great for most hobbyist applications but for industrial stuff you may need to look at other designs. The principles for motor control that that I outlined in the video will be the same.
