Last night I was thinking of what I wanted to accomplish today and I settled on learning about servos. This morning youtube recommended this video. I did buy some cheap servos a few years ago but never did anything with them, I guess it's time to hunt them down and apply what I learned.
I have no idea what your saying 60% of the time. Why do I watch if I don't know what your talking about? Because I love electronics and your voice is relaxing to me.
1. To understand how to control servos as a blackbox, buy Arduino and a servo, and then code to control the servo. 2. After that, if you care about what's inside the servo's control circuit, look it up online to build your own servo from a DC motor.
You also could use a 2 transistor "multivibrator" setup, which btw also offers the pwm counterpart exit for a proportional opposite motor control. This comes handy if you need to control 2 servos with mirrored turns, such as pulling or pushing synchronously an object from both sides.
wow, this is a great channel, you are not just another theory only or salvaging and hacking only electronic channel but you actually know and explain the theory behind them. so there are channels dedicated to pure theory and calculation like professors that hardly do any hands on practical projects, and there are channels by electronic hobbyist that are high school drop outs and could hardly explain a simple theory but just pure hands on electronic salvaging, but this channel is the best of both worlds.
I really like your videos I'm working with servo motor and I observed it's not turning up to 180⁰ but your video helped me alot I don't even know what to say because this comment session is not enough to tell how explanatory your video had always been. Love you men 😘 😁
I love your handwritten explanations. And everything else in your videos. They are always very well explained and thorough - nothing is taken for granted and they are funny as well. And you keep covering new areas. Being an old electronics engineer myself, I still learn a lot from you. Keep it up!
links to other videos for the mentioned components/consepts like 1) stepper motor, 2) duty cycle of a rectangular signal, 3) h-bridge, etc. would be very helpfull. if every video had these, a noob in electronics would be able to drill down recursively to the absolute basics, like voltage, current and transistors and then back up the "tree" to understand the initial video in every possible way. and that would increase views as well, and increase your revenue. just a tip. keep up making these videos, they are very helpful. i find myself frequently referencing to your channel after reading a piece from "The Art of Electronics" for the real world examples.
The Arduino Servo library can actually define the min max values in microseconds with the command : attach(pin, min, max) The default min is 544 and max is 2400.
you should do a video on galvos/galvonometers! they are like servos, but can only move around 90 degrees, but are incredibly fast and precise, which are used for items such as laser machines.
Hey, fantastic video! I remember you saying in one of your Q&As that you make your videos in English because it's good practice, which I immensely respect. In that spirit, I'd like to point out one small wording mismatch -- when talking about the 555 circuit as opposed to the Arduino, you say 'capacitors, resistors, etc.' "in this constellation" as you show the schematic. I believe the word you were looking for was "configuration". I want to reiterate that this was a fantastic video, and the only reason I mention this is because you have expressed a desire to sharpen your english... not to be a grammar nazi xD Thanks!
The difference between a trained engineer and a geek is that the engineer knows why it happens and how to apply it, and the geek just how to apply it. I am neither of them, consider me a tech voyeur. This is great content! Thanks
it's a grate video to learn basics of servo motor working. can make video on industrial ac/dc servo motor and how to control them with servo driver using microcontroller insted of plc it will helpful for me and any other also
Another great and informative video. Would be nice if you guys made an applications video comparing the 3 common motors (DC, stepper, and servo) and when to use which one.
This signal is called a PPM signal "Pulse Position Modulation", even though it is a specific kind of a PWM signal. Just wanted to drop that information here. Viele Grüße aus Düsseldorf
Well I'm planning to modify my Arduino Line Follower as a Wall Follower using a Sonar Sensor and Servo. This info was very useful, thanks from Bangladesh. Awaiting for more of your videos
I was about to say, about the 1ms to 2ms pulse width that for some to utilize full available rotation you have to go beyond. But nontheless, as always you covered it later!
Back around 2004 I 'hacked' a servo to rotate 360° continuously. At the time I could not readily purchase one, or the cost was outside my budget. {Also at that time I had a couple spare servos I could hack.} I learned two things from this endeavor: (1) Unless you ABSOLUTELY HAVE TO hack a servo for this purpose, just PURCHASE a commercially made servo that rotates 360°. (2) Being at the age of 43 at the time {in 2004}, I was starting to need eyeglasses...😊
Congratulations for your contribution. Seeing your explanation of how a servo works, and looking at the KC518 datasheet gives me ideas for what I'm looking for. I made a comment on the MEKATRONIK channel about what I am looking for. Suppose a servo assigned to a 3 position switch on the radio. Target: In the high position or 1, which is supposed to be all left e.g. the OFF switch. In the middle position or 2, where the centre is assumed, a ON switch 1. In the low position or 3, where it is assumed to be all right, switch 1 ON plus switch 2 ON. It could also be, pos 1 switch 1 ON, pos 2 both OFF, pos 3 both ON. The doubt, it will be easier to use the output that gives the servo to the motor or use another circuit that interprets the PWM signal input to the servo. After watching your video, I can think of ways to use those outputs to the MOSFETs and combine them. If I'm not misinformed it would be 1ms for min, 1.5ms for centre and 2ms for max. Can you think of anything? Do you know something similar? Can you help me? Sorry but I didn't translate it myself. Thanks Juan Translated with www.DeepL.com/Translator (free version)
+GreeatScott! I find it amusing when you say "in this constellation" We would probably say configuration since we are taking about "figures" (diagrams) rather than "stellas" (stars)
The continuous servo hack is really more of a "geared motor" hack, because a *REAL* continuous servo will have a feedback controlling how _fast_ the motor spins, so it instead of trying to regulate position, will regulate RPM, or rotational frequency.
Very good and useful video! Great work! Now, as it was said earlier, it would be really awesome if you did an Electronic Basics video on 555 timer, as it seems to be one of the cornerstones of modern DIY electronics. But, for the same reasons, such a video may take a while to make
Hmm, using a 555 timer instead of an arduino/ATTiny. I just asked a few weeks ago on your buck/boost converter video if it was possible to use an NE555N instead of an ATTiny. Thank you for showing the other side of electronics, sans microcontroller.
