Hi everyone - It's come to my attention that there has been someone masquerading as myself, responding to some comments here with a link to a Telegram chat to win a prize from me. THIS IS A SCAM, I am not holding a contest, nor do I have a Telegram account. PLEASE DO NOT RESPOND TO THESE MESSAGES!! It's happening on a lot of my videos, I'm taking steps to remove them manually, but as I have 162 videos, it will take some time. If you do run across a suspicious comment, I would appreciate you letting me know at info@dronebotworkshop.com. Thanks! Bill (The real one!)
@Bill I was wondering if you have any info or videos on how to connect NEMA 23 steppers with Arduino Mega or Giga even a Uno. I have a few raspberry pies and I wanted to make a CNC controller but I can even install LinuxCNC so I thought I would try out Arduino excellent video by the way take care Bill
Just so you know the quality of the content here. This is waaaay better than the Automatization lab on my university at the Engineering faculty. Regards!
I am currently a junior majoring in Computer Engineering. I can spend hours looking for specific information out there, and it drives me crazy. You bring all the essential knowledge in one video and with excellent structure and explanations. I cannot thank you enough for these kind of videos!
As an aircraft mechanic, A/P, with an Inspectors Authorization, IA, I’m just getting into this world…but I find your videos VERY informative and helpful. Thank you and I really appreciate your help in understanding in a way that I can develop my own projects. Cheers, new sub here👍
Not to be ignored are the motor controller boards that communicate with the Arduino via I2C. They only require two of the precious IO pins to drive your robot’s motors, and the libraries available to control them take care of all the setup details. People new to the sport will be best off sticking with brands such as SparkFun or Adafruit, and picking motors from the same places that they indicate are compatible with the board you choose.
Great content as usual. Minor nit pick. Vbe is 0.7V for bipolar transistors; Vce(sat) is 0.3V. When using FETs, keep in mind that they cannot change from OFF to ON (or ON to OFF) instantaneously; there is a slew rate. When they are in this intermediate state, there is a voltage drop and a current flow; so they have to dissipate power as heat. It is nowhere near as bad as bipolar devices, but needs to be kept in mind when switching them very fast.
Although I have watched many of your videos I rarely but I wanted to stop and thank you for the excellent content that you provide. I am highly appreciative of your presentational style you're calm demeanor and your thorough and useful explanations. There have been multiple times where your videos have helped me understand concepts well enough to implement them in my experiments and projects and this has enriched the quality of my life. I sincerely appreciate your efforts. Thank you
H-Bridge devices have so many different applications. They can be looked at primarily as a motor controller but I also use a H Bridge to convert the digital signal out from an Arduino to DCC +-15V square wave for HO/OO scale model railways. Very versatile device.
This is a FANTASTIC treatise in motor control options!!! With some excellent tips and the 98% speed warning!!! I can't get enough of your instruction! Well done as always!!!
I am always amazed how DroneBot Workshop present each topic in a very comprehensive and yet concise manner. It's like I'm reading a book but everything makes so much sense. I hope you would consider presenting courses in EdX, coursera, etc.
Bill, I have watched many of your videos over the years. I have seen some of these motor drivers in those videos. But it is wonderful to have them all in one place compared to one another. It took me a few days to make it through this video. It is a great reference video that I am sure I will use over the years. Thank you for taking so much effort to create it. The quality is amazing. I really like those cytron boards. I especially liked the feature of it testing a motor without the microcontroller.
This is an amazing video, super comprehensive and offers multiple alternatives for different use-cases. Better yet... it comes with an attached article with source code and library links. BRILLIANT WORK
I just rceived my motors for my remote controlled lawnmower project yesterday... and today this video! Coincedence or Syncronicity? Either way... thanks Bill!
Im just a hobbyist when it comes to electronics and have been slowing learning an self teaching myself for a few years know and even though I may know how to use h bridge controllers I still feel you can learn more about things by listening to others especially ones who are well versed or educated on the topic I just found this channel and subbed after the linear ps video because of how well you did in making a high quality informative video an because you don't drag on one thing forever explaining it you condense the important points with enough detail to get the message across then move on and that's why these videos I feel are packed full of information in a decent run time and can be watched with ease.
Thank you so much for this video - I have been trying to wrap my head around the different microcontrollers for dc motors and always ended up confused! Such clear explanations-as always 🙏 Love your work! ❤
Kind of a long video, but a ton of info was presented, all in a very detailed format as usual. Thanks for taking the time to put these together, folks really appreciate your efforts!
You really know how to transfer knowledge! Great job, thanks for be so professional and provide excellent videos, very well explain and easy to follow.
Let me say, Your lisp DRIVES ME UP A WALL!!! BUT DAMNIT I cant quit watching your videos because they are so DAMN GOOD...... FU#@....... Great videos!.
Just to add ... if you try to 'roll our own' H-bridge, timing of the 'switches' is important! It is VERY easy to momentarily short out to ground and release the magic smoke!
Fantastic video, it's just what I've been looking for. I've been building a 3d printed tank and I got stuck trying to figure out the electronics side of things, this video has been incredibly helpful and should allow me to move forward with the project.
Great video! You can always expect the quality and information to be excellent when a new video pops up. Thanks for all the time and effort you put into these.
Very informative content. I enjoy it. lol, this guy is interesting. I don’t think I’ve ever heard someone pronounce the arbitrary names of any circuit board so many times. I don’t think he skipped a single time saying the entire name of board when talking about them. Very funny. Most people would shorten them or only refer to a small portion of the name. Interesting guy.
I've got to admit that at 70 I'm too impatient to actually learn to code. I usually try an find some online project that looks like what I want to do and give it a try. Sometimes it works and sometimes it doesn't. But from that effort I pick up enough clues to come here and choose your video that seems about right, pay attention and usually get the thing going the way I wanted. Thanks for doing what you do.
😲 You forgot to say "Wipers" @ 50:24. 😄 I so love your videos! Your illustrations, diagrams and tutorials are the BEST! And I mean that. I'm still keeping my L298Ns. I'll use a wall wart on a project with no wheels. A Pinball Machine!! 🤣 Thank You, Sir!
Love the effort you put in in your videos, I've come back to this video again and again as reference for the motor drivers. Appreciate your content a lot really helpful ❤️
Thank you for another Great video, to complement this, I would follow up by showing how we can do current sensing on all, and also how to use an different types of motor encoders to demonstrate feedback control loop concepts.
At 3:40 I think you are confusing the base-emitter voltage drop of a bipolar transistor (about 0.7V) with Vce(sat) which is often on the order of 0.1V, similar to a MOSFET. Otherwise, amazing video. I can't believe the work you put in here!
This video and tutorial is absolutely amazing! Thank you so much for putting together this clear, concise, tutorial. So much easier to understand! Looking forward to watching all of your other videos!
that was very revelling & did infect answer a questions or tow i have still have to get in to wring the set up. And loop for the ono but at lest now i may have a drivers to handle the job thank you a lot once has figured out how to put it together on my lath.
32:53 This is the diagram I was looking for. I was wondering why there was no separate gnd/voltage for the logic. I didn't know you could just tie the gnd to the motor negative for logic and use the arduino 3v. Thanks a ton, liked and subscribed.
Great work Bill. I'm using the TB6612FNG in my latest project but only driving one motor. But thanks to your vid I've just ordered a DRV8817 to replace it. Keep up the good work!
BTW: I see eBayers selling Wheel Chair motors without wheels. I found that Harbor Freight pneumatic wheels with 4 bolt holes line up perfectly, and cost around $5. You should knock out the inside bearing to fit the hub nut, and fill the tire with Fix a Flat or Slime since the valve stem will be on the inside mount side. I think they are the 4-5 in rim, white wheels. The IBT-2 45 amp motor controller works on a wheel chair motor. You can get the IBT-2 cheap 2 for $15. I bench tested my Wheel chair motor yesterday and it only pulled 10-12 amps under no load so there is plenty of amps left for a load. I believe DWS said the IBT-2 were 30 Amps continuous. 43 peak. I just looked on eBay Wheel Chair motor prices have skyrocketed They run from $130 to $200 each. It might be better to look on Craigslist and buy a whole chair for $100-300 from an estate sale. 5 years ago I got 2 eBay motors without wheels for $75. I also had 2 chairs given to me when a friend's mother passed away
This is a very well conceived and instructive tutorial. However, the most versatile motor controller I know of was left out. This is Basic Micro's ROBOCLAW. It comes in different sizes but the most common is the Roboclaw 2x7 capable of driving two motors drawing up to 7 Amp each. This controller has the ability of processing signal coming from motor encoders and controlling the motor's speed via a PID (Proportional, Integral, Derivative) feedback loop.
Great presentation as always! Cytron urc10 robot control board, which is UNO R3 and cytron 10/30 amp driver all on one board, is great project option. One power hookup and lots of pins.
That helped, considering I started in industrial when MG set's were still commonly in use. The current rating is amazing in some of these small packages.
excellent work!!! thanks for your outstanding presentation...your consistent, clear outline for your videos makes them superior to any other source. You were the first source for my arduino learning process and as my level of understanding grows...you seem to be there with a video on the topic. I am a noob trying to control 12v powerwheels toy with my 80v lawn mower battery...needing to get the voltage down to 12-18v...from your explanation, an h-bridge does not seem to work...or am I missing something...is there a standard way to control lower voltage, lower cost dc motors with a much bigger voltage source...thanks again
Great video, helped a TON with my project. Sadly I already ordered 5 of the L298N, but I got them super cheap so went ahead and ordered the ones I need, the TB6612FNG. Problem with the first one is that huge heatsink, and I only need 12v so 2nd one was perfect.
would you like to make a video in your channel how to build quadruped robot by using servo motor shield and arduino.? as i do not get anything clear explanation about it from other channels so far
I have this delay timer called YYC-2S it is a brand new timer but some the delay settings inside do not work as advertised. The timer has NUVOTON N76E003AT20 IC on it. It has Four, seven segment displays on it and four button controlling a single relay switch. Can assist with reprogramming it
OMG I ve been for ages trying to drive a dc motor with PWM but I was stupid not to check the datasheet and was trying to drive the PWM on the IN1 and IN2 pins which only worked at very low PWM Freq 100hz... Im going to try it using the Enable Pins later. Thanks for the tip
Excellent. Please make another video with Arduino uno R3 and with detailed code. What it is capable of? How many DC motor types it can control together with auxiliary components.
In simple terms when using DC brushed motors, what is the main difference between an ESC you buy for a hobby grade RC car & the receiver/motor control board you find in a toy grade RC car? It seem PWM is what separates them?
This is really excellent, I have now watched the whole thing. If you have any info on reading the current sensing from L298 on the Arduino Motor Shield Rev 3 I would love to see it.
Sir Bill, tnx for sharing your knowledge without so much jargons. 😂 wish you more success. One question pls, what happens when you use the md25hv with a much larger motor? Specs says 12v 90amps and it has a high inrush current too. I use a old server psu to power it up but i wanna reduce it as its too loud while im troubleshooting and doing repairs on other components. Its a dual pump air compressor.
Excellent video as always. However this time I don't understand your excitement over the Cytron library. Or the need for a library at all for that matter unless it's a generic one to avoid shorting the bridge. Did it fill the function of a generic, lightweight library? I would've thought something like that was top of the list when looking for libraries.
