I gotta say. I"ve checked out some of your other videos, along with this one, and i gotta say... Outstanding. I"m 60 years old, retired long haul truck driver, disabled. I needed something to keep my mind right and a friend suggested that I get back in to some sort of electronics (as I build and rebuild Speakers, hobby and the price of a good speaker was out of this world, so I make'm. Diving into the world of micro-board computing and processing, has been an awesome adventure for me. You are never to old to do something new and create wonder in ones life. It's these kinds of instructional that make it... Not Easy... Fun and keeps the mind going... Thank You Sir... I'm not sure if you really grasp the gravity of how you help people, but this old dude... Pain is now a background thing. I now use no Pain Meds, I use a sleep aid but that's it... The Mind is a terrible thing to waste... Learning will do things for the body you have no idea... Thank you... I guess one could say...

You're not that old Charley. 60 is just a whisker past middle age, so still a puppy in your prime. Congrats for keeping the grey cells firing! You might want to look into 3d Printing. Its all circuit boards and stepper motors and really gets the creative juices flowing. Its led me down the path of learning CAD software and its really cool once you get over the initial learning curve. Good luck buddy!

[@terrencefish7284]

@@jackdeniston9326 Hey Charley. I'm about the same here. 61, disabled, and enjoy filling my time working on various DIY projects. I did have three years of electronics in high school, but didn't pursue a technical school degree, or try to work in the field. I went straight to work doing construction until my body finally gave up. I had forgotten how fascinating I found electronics to be. I am just so thankful for all the people who are willing to get on the web and share their knowledge, it makes it much easier to learn all over again.

I am an retired industrial controls tech that spent the last 33 years of my career with a very well known large company. Almost everything we did used expensive PLC's and robotic servos. Industrial servos used in industrial robotics are very expensive brushless motors with encoder feedback. (imagine paying $4,000 just to have a brake disc replaced in a robot servo!) Now that I am 69 years old and retired I am just trying to keep my mind sharp by playing around with Arduinos and other small controllers. You are a great teacher and your tutorials are very helpful, please keep up the good work.

You do not have to do this but I am so glad you continue to make outstanding videos with patient and complete explanations and software to copy.

You're one of the best of teachers I know. Amazing presentation, superbly laid out, and wow, a super organized lab. Would love to spend all day in one of those really. I just started with the Arduino, and have to say, it's been a topsy-turvy but fun ride. And none of the other assistance I got from the internet has come close to the way you have put it out here.

I send my salutations and appreciation along the line of Mr. Charley Edwards. I'm also retired, 67, spent my life in biological/biotech research and international research management. Now, retired, searching for a past-time offering great mental activity. I've tried advanced math, astronomy, and - now - electronics. Thus, stumbled onto your videos and am absolutely delighted to learn from you. Your presentation, though often using acronyms or abbrev's unknown to me, is reassuring and comprehensive. Your approach to such a complex topic as electronics (to the novice) is well structured and fun to attempt to apply principles revealed and suggested. I am avidly digging through your past presentations in order to learn about setting up and controlling stepper motors in order to control telescope mounts via a hand-held remote. So far? Not so good, have ordered more materials to attempt it again and review your coverage of specific aspects of stepper function and arduino-based control. Fingers crossed, I'm trying to move forward but for a total novice in the field, it's sadly missing something. So glad you're here and presenting as you do. One last thing: I am SO envious of your accumulation of gear and parts and their organization is a great model to follow. Keep up the great programming!

[@3dcriacoes763]

I totally agree with you! What a wonderful guy giving us this knowledge for free. And what a workshop to imitate (impossible in my case once I work traveling).

[@edkonzelman2749]

Many thanks for your tutorials. I've have used Arduino, ESP8266, and ESP-32, ESP-32 Cam and Raspberry Pi modules for several years now, but I find your turorials to be excellent: detailed enough for the beginner, but sufficiently paced so that an expereinced viewer like me does not get bored. One minor point in this one: the units of torque are force-length, ie ounce-inches, not ounces per inch.

[@jobloggs3787]

There is a big difference between people that know there stuff and others that can explain it to others that don’t.

[@technojack3719]

I'm currently working on building a small walking robot that uses fishing line and springs to operate the legs. I originally envisioned using servos to spool the fishing line and lift the legs, but the tiny servos I had in mind didn't have enough torque to lift three spring-powered legs at a time and they only revolved 195 degrees, which would only lift the legs a fraction of what I needed. I had heard about stepper motors, but didn't know much about their function. Since watching this video, I decided to replace the spooling servos with stepper motors and initial test are very promising! Your videos, as always, have been a huge help in leading me through my understanding of robotics and electronics. Thank you!

[@randywetzler5976]

Dear Bill. I'am so glad that i found this video and your channel. I'am a HamRadio Amateur and i'am about to develop an automatic tuner for my homemade magnetic loop. Since then i tune manually with an normal motor and some switches to minimum SWR, this is annoying some times so i want to automate this. Therefore i decided to use a stepper motor and an arduino. Till now i am way behind of beeing familiar with programming microcontrollers and steppermotors. Your video brought me much closer to this and finally to not giving up hunting my goal. Many thanks for this. My english is not very skilled so i hope i put it right. 73's and all the best.

[@whitefields5595]

One small point. At 46:40 you should tell folks to turn the A4988 pot fully ANTICLOCKWISE to set the current to zero BEFORE connecting power, then wind it clockwise to increase. If by chance the pot was fully clockwise then there is a risk of magic smoke from the coils. Suggest you just overlay a comment onto the video. Apart from that, I followed your instructions and all works well, thanks.

[@Dronebotworkshop]

That's an excellent point, no one wants to see "magic smoke". Thanks for bringing it up, much appreciated.

Great stuff, I'm literally two weeks old into learning about the Arduino and electronics in general and this was so helpful. Thank you! What I'm trying to do is to use a NEMA 17 Bipolar stepper with A4988 and a rotary potentiometer to control speed and a button to be able and reverse direction. If you have any advice on how I can go from what you describe here: ( NEMA 17 Bipolar with A4988 - 36:41 ), to what I need i would greatly appreciate that. I'd like to compare the sketch and wiring from what I need to what you show here to get a better understanding of how I go from one to the other.

Having worked in this industry for more than 2 decades, I have to say that this video is the first AND most accurate I've seen to date. Some improvements I would suggest is to delineate the Static/Holding Torque a bit better. Static Torque is an indication, but the Motion Torque is the key. Detent torque is typically on the orders of 1/10 or less of the Static Torque. Would you consider making a video for closed loop operation? By the way; your workbench is a dream. So clean and well organized!

[@virgenalosveinte5915]

One suggestion: In the code for manually stepping the a4988 with nema17, if you remove the delaymicroseconds() between the digitalWrite(HIGH) and digitalWrite(LOW), the vibration of the motors is significantly reduced, and you can still control the speed with the second delay (after LOW). Im not sure if this can cause inconveniences but its working fine for me. Amazing video!

[@jmlocci]

Very clear video, thank you. Some may want to know what that "StepperMotor.setSpeed" entity represents and what unit it has. I figured that the calculation of this parameter is : 2048 * desired angular speed in rev/s (rps) * 0.6). Example for a quarter of a turn per second (0.25 rps) then setSpeed = 2048 * 0.25 *0.6 = 307.2, which corresponds to 1 rev in 4s (4000ms). It is homogeneous with an angular speed in steps/s.

[@agudahamed9034]

Your explanations are extremely clear and made things easy to understand. you are great sir.

[@glrider100]

I have a couple questions: 1) in your diagrams you have 2 coils,(A and B). When cycling between coils to make the shaft rotate, what's to stop the shaft from actually going backwards to the first coil? simply flip-flopping between 2 positions and not actually rotating. 2). The coils obviously have polarity. if given a motor, without any kind of wiring specification, how do you determine which wires belong to which coil, and more importantly, the wire polarity?

[@xiro6]

thanks a lot,i always strugle with arduino but your explanations are cristal clear,and you take nothing for granted so is easy to follow you. teaching arduino its harder than it seems,but i will finally learn to really use it thanks to your videos. i dont consider myself dumb,i build my own CNCs,fpv drones when no drones or drone parts were still at sale,etc,etc but arduino is "so easy" that steps are always skipped and i get lost. well,maybe im a little dumb,but still i started with the wrong foot.

I did this with a nema-17 stepper from a 3d printer using your sketch. I altered it to reverse direction with a switch. Good explanations. I'm 79 retired IT professional and still learning.. Edit: Received ULN2003 boards and28BYJ-48 steppers. The first sketch didn't work. Found these steppers didn't like a speed less than 120 for a long (1/2 turn) move. Changed the speed to 120 and sketch loops ok. (misses steps?) Edit2: Was the clone Uno. The real Uno runs fine.. On another note: Nano clones work fine.

Always wanted to learn about steppers. This explains them really well. You put out some of the best videos. Thanks!

Your teaching is excellent and I especially like the way you explain the code.

Thank you Anthony, that is very kind of you to say.

Bill, you are an international treasure. Keep making these videos buddy!

Amazing video, this is genius level explanation. This has helped so many people understand a topic with a very well thought out approach. TY need more of this.

Thanks, one of the best stepper vids out there. Another dimension to this is to convert the rotation of the shaft into linear motion either with a rack and pinion, ballscrews, geared quadrants, etc. I want to open a series of greenhouse roof windows using steppers but I am struggling to find the right hardware. Most of the stuff appears to be too weak, designed to show the principle rather than hook it up to something meaningful.

Thanks for the nice comment about the video, much appreciated. As for larger stepper motors for your application you might look at Anaheim Automation or Omega as they distribute motors designed for similar applications. www.anaheimautomation.com/products/stepper/stepper-motors-list.php?cID=19 www.omega.com/subsection/stepper-motors.html

Thanks for this. I'm in the UK and I'm looking in the wrong places, so need to dig around more.
