Many years ago, I had an idea which I implemented and ended up inventing a reversible motor-controller using bipolar transistors. Later on, I found out it was already a thing called an H-bridge and that using MOSFETs would have fixed the problems I had with my version. Sometimes reinventing the wheel is a learning opportunity. 🤷

Hey can you help me with my H bridge l298n motor, it outputs 1v (maximum) though it’s connected to a 11.1v power supply source through the 12v vin. I need 6v at least to run my motor at its perfect speed

Thank you for bringing the module in the picture. Very well done !

I really think you channel is one of the best out there. Thank you for all that you do. Much respect from Vegas.

Thank you very much... Your videos are really helping us

Just starting out with arduino and I'm really thankful for your videos! So informative, easy to understand and pleasant to listen to! Thanks a lot!

Once again, a perfect video. You gave us all the specs up front and a side-by-side comparison between the H-bridges, and went all the way through coding and building a "Pretty Ghetto Robot Car"! You had me ROFL with that line! Should have made that the title! Liked and subscribed!

Many thanks for yet another wonderful video!

Great content! Very informative and easy to understand.

Thnxs Bill. As usual, very well explained !

An excellent motor driver replacement for my mobot. Thanks!

This was really useful. Many thanks.

awesome. I was able to utilize this build to control an automatic herb watering pot for my mom. I was attempting to use transistors because I didn't have any MOSFETs but it wasn't enough power. I had a couple of TB6612FNGs sitting around for a car project I planned a while back so I used it for this. Thanks again for the comprehensive tutorials. Cheers!

Well done Bill.. what a car! you must add a picture to the Drone bot hall of fame! Have a Merry Christmas my friend!carry on and thanks..

You sir are a gentlemen and a scholar. The amount of effort you put into these videos is just amazing and I cannot thank you enough for all the help I find on this channel and your website. You contribute so much to the make community and are such an awesome teacher, make that Professor.

Nice little replacement for certain projects...thanks for sharing...

Very helpful information.

amazingly good explanation!! thanks

Thanks for bringing this new board to my attention. I still have my Original project that I made from your first demo. I've kept it as a reminder from when I started working on DIY electronic projects. So I’m ordering in a few of them for testing. I have a small track robot kit sill sitting in its shipping’s box. About a 1/4 the size of the first car. The new board is a perfect size for this little bot! I am planning to have this one setup to be driven by a smartphone app using Bluetooth. I believe your back east and winter is taking hold , for me I’m going out to mow my lawn (I’m in Vancouver ) lol Thanks for sharing your knowledge and have a wonderful Christmas

Cool. Fun. I enjoyed your project. It's very nicely done. Appreciated. Thank you.

After I watched this video I bought the emakefun ps2x motor driver shield .. it has the tb6612fng controller, plus a few other bells and whistles. What I found that was kinda cool is the playstation 2 controller port on the board. It works, I used it with a cheap knockoff Ps2 wireless controller.

THANKS!

Thank you. Very well explained and illustrated. Just one question, can the TB6612 be used for a 4 wheel drive project?

Very informative video. Are there any module similar to the TB6612 which is in a smaller form factor but can withstand higher voltage and current?

Great video.... learned alot...... one thing i'd like you to go through would be your workshop setup.. looks like you make alot of good design decisions ... might help us organise ours or rebuild using soem of your tricks !! maybe you might have done things different .... things you fins very handy .. like sound controls in front of desktop etc... just an idea !

Thank you very much for very precise and descriptive explanations about this module. I have a problem to solve regarding the stepper motor driver controller module 36820. This module can only drive motors having less than 800mA. Can I use this TB6612FNG module along with the 36820 module to increase the current per phase of a stepper motor? If possible how to connect them each other?

If I recall, the maximum voltage for the chip was 6.5 V. Some fresh alkaline batteries I have checked come with as much as 1.6 V actual and lithium batteries may be even 1.7 V. Those numbers of course are unloaded readings, but in any case 4 of them seem to exceed the maximum specified voltage for the chip.

once again a very well prepared and informative session, many thanks. I have a question if anyone can help me with it, I need to manage 6 stepper motors on a small project, is there a driver that you can suggest which does not consume huge amounts of my battery cheers

As with the L298N, the TB6612 can drive a single motor with double the current rating by parallel wiring the inputs and outputs. For two motors at double current use two controllers.

Thank you , DroneBot Workshop is great, I need do a sketch to drive a larger motor 24V and would like to use a Hbridge using mosfets but i also must be able to do speed controle . Im using a garagedoor motor. would like some help please

Thanks

Great Video! Keep up the great work, you are really good at this, plus I need your help all the time to learn these controllers. I just and M.E.

What software did you use when you showed how the Arduino connects to the motor driver and potentiometers? It looks vaguely like Fritzing, however it has animation that shows how everything connects together.

This is a terrific channel you have going here! Thank you! I am working on a similar project as the one in this video but I need to know how to detect sudden dc motor stall current so I can stop the motors. I was thinking maybe I need to determine how to trigger stop based on rate of rise of motor current? A follow up video on achieving this would be phenomenal. Thanks again.

A hall effect sensor maybe would work. At stall, the current is at max and so is the magnetic field which is what the hall sensor detects. It is also non-contact.

Also, I found another model of H-Bridge that has a voltage output proportional to current output for over current detection I think.

how are current capabilities similar when one is 1.2A while the other is 2A ? or are you comparing 3.2A peak current to 3.0A ?

When a module only has pinout markings on the bottom and if it has no buttons or displays on the top, simply mount the pins upside down making the bottom of the module the top. Now you can use the module and read the pinout.

Are there any informations about responce time? It is important too.

In order to reach the smallest size of driver it is better to take a look at the DRV8839. It is powered from 1.8Volts.

size is not everything 😂, did not expect that from you🎉🎉❤

If you're breadboarding, and don't have heatsinks or indicator lights sticking up, just solder the pins on the other side, and put the module in the breadboard chip-down.

Coming from the l298n, ehat would be the most minimal connection to a Xiao for just speeding up a small DC motor ? ( no brakes, no nothing, just speeding up or slowing down the analog way from 0 to 255 value ? ) ? Could I simply connect the standby to VCC and all the other inputs NOT connected ? Thank you

does pin AI1 have to be connected to a pwm pin? Im trying to drive 4 motors but only have 5 pwm availible. Was hoping to use 2 of these boards. Many thanks.

What if you Sauter it upside down? That might fix the bread board problem

Does this controller handle the current after the motor shuts off or do you need a diode to handle the transient current. I want to use this on a 12v rs555 mabuchi motor.also does the stall aperage need to be considered when choosing a controller?

You inspired me to design the circuit as smallest as possible to run a single or 2 motors via wifi. Till now, I found ESP 01, AT328P chip with L293D chip. Another Idea is thinking about using ESP 01 directly to control motors.. Can you please let me know if any other possibility of reducing is size further. Great work.

Great

Hey! How can I use a mini L298 N H brigde? It does not have a enA entry

What if you were using a linear actuator and needed reverse polarity?

There are quite a number of motor drivers. 298 is still a good choice if you have a high voltage motor. Other than that there are better choices than the 298. The tb6612 generally needs more control pins (3-4) than others such as the mx1508 or L9110 (2)

Can we use this in drone with 8x20mm coreless motors? Will this be too heavy design wise? I am planning to use arduino nano with 2S battery.

Can you do a video about the mcp4725?

Is there any way to analize the ODrive motor driver and probably show us an alternative way to DIY the same or similar with arduino modules e.g. ATtiny85 or Nano + H-Bridge MOSFET drive incl. closeloop encoder with CAN bus connection in a much cheaper way for DC motors e.g. 24 V / 50 Amps ? I would appresiate that much !!

I have been trying to figure out the right way to use 2 hoverboard motors controlled independently with remote control. Would i need two esc and can I use them together with arduino or should I use rasberry pi? Would 1 arduino and 1 esc allow independent usage through code?

Interesting video :-) I intend to convert one of my son's RC car to use Arduino and wireless that can be controlled with the smart phone.

Bill, like to see this project with the HC-R04 to control this.

Thanks a lot for this really useful video! I have one question about the standby function: how can I make use of this? Is this simply a digital HIGH or LOW in order to let the module know that it has to be active or not? In other words, if STBY = digital.Write LOW, will the module be placed into standby mode?

@beanapprentice1687

2 жыл бұрын

You are correct. You can use a digital output pin to control the state of the chip. If the standby pin is being signalled HIGH by the Arduino, the motor driver turns on. If it is being signalled LOW, the motor driver will turn off.

Can it do 1 coil, 2 coils half stepping via the microcontroller?

Cool module could power a tiny robot an oversize nano bot .👍

If your module has the silk screened connection labels on the bottom, simply solder the header pins to the top of the PCB and plug it into your breadboard 'upside down'!

L298n motor driver can give an output voltage of 5 volts... Is this same applicable for TB6612 module ?

How not to brake with what function or with what pwm?

At 2:41 States the output current of 1.2 Amps is that per motor?

Im having a real hard time with the TB6612FNG standby pin. Where/what should I connect it to? I am using a Raspberry Pi Pico for my board. I have no trouble with the L298N, but this TB6612FNG is making me want to crawl the walls.

Sir... Can i use tb6612fng for analog input?

For batterie powered toys or 3.3V 1.2A devices at all use the TB6612FNG but for long run devices like 3D printers or CNC use the L298N 5-24V 2A per motor ist a must.

There are other motor drivers in the world besides the TB6612FNG and the L298N, you know. I doubt that printers use either of these motor drivers. Instead, they use high-power MOSFET drivers. Same kind of transistor technology as the TB66, but more powerful.

Nice tutorial. But from where is that noise coming when the bot is moving slowly? That beep sound?

Well, I came here atlast hope to find my solution on using this TB6612 controller. I am using this controller on a toy car, from the start it behaves different like two motors don't running same speed at a time, one motors runs fast, and the other runs 3/4th of a speed of motor 1, even though I gave same speed as 200. What is the reason for this? I already asked this question on most platforms, but doesn't get a sourceful reply.

I'd recommend the TC78H660FTG from Toshiba. You can get breakout boards for it for as little as $5 AUD.

Hi, I tried to work with the L298N board, but for some reason, after a while, it makes my 200v breaker trip :/ I have no idea what's wrong, I'm using a 12v power supply with 3A max. Any thoughts? maybe I'm missing something in the code? , maybe it draws too many amps after a period of time? Thanks!

@beanapprentice1687

3 жыл бұрын

there is no way the l298n could draw enough current to make a mains breaker trip. The motor driver would explode and stop drawing power long before that, if you could somehow load it enough and override its built-in thermal protection. The problem is most likely a fault within your 12v power supply which is connected to mains power.

Not quite sure why I need a pot to control motor speed. Shouldn't the environmental feedback from hardwired switches or Lidar input manage that?

Did you ever try the dvr8833? It is a little less efficient but it only uses 4 gpio pin instead of 6. I love how you explain everything as detailed as you do so I'm really hoping for a video on this driver! I'm working on a project that has 8 independent motors(small n20 with encoders) so 2 less gpio a driver would save alot

You do realize that you can control the TB6612FNG with only 4 pins? Just attach the pwmA and pwmB pins to 5V so they are always on, and instead is the in pins for PWM and ground. Same thing applies to the L298n.

Sure, but in this case there is no point in using the motor driver at all. Just connect the gate of the mosfet directly to the Arduino.

It's as if the module manufacturers just recently discovered something called MOSFET. Why did they mass-produce inefficient, bulky motor controllers based on BJTs for so long can only be chalked up to a sales tactics that has in mind that down the road they would release the mosfet-based version and expect a mass-replacement of motor controller modules..

I think it's mainly that all the hobbyists know about the old, bipolar devices and all the tutorials use them. I've been using a similar H-bridge, the MX1508, and those modules are often mis-advertised as L298N modules. For most hobbyist applications they're probably a better option than an actual L298N.

the L298N module has an on-board 5v voltage regulator which is what allows you to power your arduino from it. The TB6612FNG module however does not have an on-board voltage regulator, so you need a separate one connected to the main battery to power your arduino.
