Most arduino tutorials go from basics, like turn off/on a pin, flash a LED etc. and by tutorial 10 you're talking fancy talk like using for loops and so on. With Great Scott though, the complexity is exponential. At this rate tutorial 5 will have us manipulating the universal gravity constant through software.

Agreed. He went from 101, to 102, (undergraduate classes) to class 506 (doctorate class). I pride myself in being able to at least follow Great Scott in most of his videos, even if I couldn't necessarily repeat what he said... but in this case, let's just say if he comes out with a 104 class I'm going to pretend i didn't see it! LOL

1:18 "...or a lazy person like me." If this is lazy we're all screwed.

Local KZreadr Inincreases his signal frequency to 1MHz using these 2 weird lines. Electricians hate him. 2:25

I love the handwriting when you explain!

Thanks for listening to us and continuing the series. :)

Well , you got a choice when you include Macdonalds...

I really like your videos because they are concise and force you to go deeper to understand the topic. Congratulations!

This video series is definitely very useful! I'll be able to do a lot more due to a better understanding. Thanks!

Love this video. Thank you so much for posting and keep them coming. Love watching all your project videos and tutorials. Really helps me come up with ideas for my own personal projects.

Although this vid is rather old, I enjoyed watching it. I recently spent a lot of time finding this out on myself and experimenting with it. This knowledge is especially usefull when trying to play 8bit sound samples by utilizing the PWM pins and using the ADC respectively. Because you need to switch on Fast PWM and setup the prescaler correctly, this video is a nice introduction for this scenario. Great, Scott!

I am glad to see more advanced arduino topics. I would love to see more!

Definitely like the pace and the details..!! Excellent tutorials..!!

An excellent video. You did cram a lot into 8.22 seconds but it was ALL gold. Other viewers, who found this challenging, might like to view the video again; this time pressing pause at the end of each topic and go back until you have a feel for what Scott is telling you. The message to be taken from this presentation is that; while the Arduino IDE/"language" does make things seem a lot simpler, it does so by hiding a lot of code in the background. This is fine for flashing LEDs but a lot of the MCU's awesome power is being hidden from you to. When one comes upon applications that need to control, or interface with, many peripherals, one will find the limitations imposed on you by the IDE, limit the applications one can tackle. Well done, Scott, for dipping your toe into the murky world of AVR programming. Be brave, your subscribers will soon realise that it is just new, not "too difficult" and will be so grateful to you for that lesson.

Thank you Scott! This was very valuable to me - you definitely earned my subscription.

Thanks for explaining the different registers clearly. I can use this info to improve some of the projects I have done!

***** Who has the patience to read the entire datasheet for less than a 6 figure salary? Would you do it for the wonderful KZread comments and around $200 that you get paid over 6 months to a year? ... while working at a full time job? Subjecting yourself to YT comments is like working in the customer service industry. You just do your job for a paycheck while a crowd of ignorant imbeciles feels like they have a right to treat you like a verbal punching bag.

*****​​ I understand what you mean. When I learned to paint cars it took me forever to wrap my head around estimating time. I finally learned to make an honest assessment of the work, then quadruple it, and I would be right on the money. It's important to learn from both the internal mindset, and for communication with a customer. After being partially disabled, I picked up electronics. Learning those important bits to look for seems quite the challenge without buying a $30k to $50k, 4 year, guided reading program, but I'm probably just slow. I think it takes the right mindset and patience to isolate the necessary details. Sometimes it seems 'lazy' is the person unwilling to get up off the couch, other times it's the person that hasn't read the entirety of "The Art of Electronics." We're all wondering along different parts of the path to understanding this stuff.

There was a time that I did not know any off it. It takes time to learn but if you keep chipping away you'll get there. I'm no mastermind, just someone who, like you, wanted to learn. Maybe just start with basic logic operators and binary. Once you understand that you'll then will see that all he was doing was flipping some bits on and off. Good luck and above all, have fun learning. :) The buzz you get when the penny drops is awesome.

great video

Very interesting... Reminds me of the "Good Old Days" of programming in assembly to speed up subroutines in a C (or BASIC) program. Brought back a lot of old memories. Not all of them good! I'd like to see a tutorial on interfacing an Arduino to the Dallas/Maxim 1Wire network.

Your handwriting is phenomenal...

This one is very usefull video! Thanks a bunch i always wanted to start converting my slow arduino code to fast code via registers

Thank you very much ! I was using a similar code to that in my multi-level inverter controller digitalWrite(outPin, HIGH); delayMicroseconds(50); but it didn't accept float values , nor variables . I think now i can manipulate your method to make it more accurate

you are awesome!

I love this series! I just hope you can make a dimmer for 220V lighting controlled by a pot or some code. :-P

finally one of his vídeos i do get it completly. just cause i did also read the entire datasheet for a school project 😂

it sounds really cool it's a lot more complicated but you can do really cool stuff at a lower level.

It is not surprising that many of those who commented (Marwan Nasr El Din) didn't 'understand anything because 'Great Scott' used an approach that confused rather than clarified how one can manipulate bits in a status register to achieve a goal. Sorry to be so lengthy, hopefully you don't reply TLDR! The code to set a 'prescaler' value in 'ADCSRA' was NOT clearly described instead a supposedly 'clever' bit manipulation statement: "byte PS_16 = (1

i like your ideas

Please create a playlists of Arduino tutorial. I love your tutorial. I have completed the basic electronics series. But unable to find Arduino tutorial playlist. Thank you.

wow! Nice tips, thanks! Now I have to read the 328p datasheet for complementary studying

Really nice. :)

i love your projects LoL

Lazy?!?! I somewhat understood it but I got to practice instead of just watching the video. Your a genius

when i learned​ this things in my engineering class i only concentrate just because of my electronics teacher is hot , this time my mind start boiling but great video great Scott

relentlessly waiting for ur reply!!!!!!!!

and if you incorporate the goto loop; at the end it will short the off phase as the rising and get faster frequency

There is two kind of people that watch this video. The ones who want to learn this and, the ones who already know the topic and they just feeling good about that they are able to understand :)

It would be nice if you could give some insights on how to write efficient code (in particular interrupts, watchdog timer and low power handling)

It's very very good

Arduino is awesome!!!

Scott. Thanks for doing all this and helping us. It is a bit. Too fast for me though and some of the things you appear to edit out maybe useful after all? It is impossible to get the pace right for everyone, but if you go a bit slower, the bright folk can always increase the speed.

Great ....interesting

Thank you

thank u sir.

It's interesting video.

i am fan of your videos, do you wanna know why ? because its GREAT. Scott.

You do have a EEPROM video tutorial? Your videos are very useful! Thank you so much!

I like to call you "King of Arduino".

This will be handy for setting unused pins on a mega2560 to non floating/input with pull up. without a whole bunch of digital write or pin mode commands

I'm definitely going to have to rewatch this a few times over to take notes because all of this is a bit over my head. @~@

So smart :)

Question on the last advance example, was all that bit math used to change the sampling rate? What was the need to keep the bits with X's? (Or was the first 6 bytes toggled for something else?)

From another topic. Will you do a video how to do my own 3d printer from old cd/dvd readers using any magic stuff (can be with 3d pen)? Actually Im bad at these things and ur the only ytber that explains so well everything :)

The "b" in bxxxxxxxx stands for binary I believe.

Long story short from above convo. BXXXXXXXX will only work with Arduino IDE. Reason is, the actual syntax of XXXXXXXb isn't supported by all Arduino systems, and you can't use a marco that starts with a number in your #define

That's pretty much what I remembered, but on checking (with a compiler), XXXXb is not valid syntax (it is valid MASM/TASM syntax, which I think is where I was remembering it from). 0bXXXX is the correct C syntax for this. test.c: In function 'main': test.c:5:29: error: invalid suffix "b" on integer constant printf("int = %d ", (int) 0001b );

hi scott. you say 101, does this mean that you have another 100 videos on arduino xDD. if you do, i would luv to see them. tnx for all you've done for my knowledge by now. the chennel is awesome. great!

Hello, do you have a video on the basic usage of that oled display?

I very like u great scott!

My project requires 16 or more leds, for a runway chaser sequence with a very small footprint. I'm trying to simulate runway lights on a small aircraft carrier. Maybe three or four leds, the first one at 100%, second at 75%, third @ 50%, and fourth @25% chasing from left to right in a repeating pattern. As soon as the four leds reach midpoint in the travel direction, another set of four leds follows from the start position, so you will have two sets chasing from left to right, and so on. When the first set reaches the end, it starts over again from the beginning, same with the second set. I have looked all over the web and have had nothing that fits all the criteria. Doing it on an UNO will not work as there just isn't enough room in the model for the large board. 555 timers with a shift register won't work as most don't have a way to make the fading effect. Can you help me with a solution? Thank you.

@GreatScott! Please let us know lots of your opinion. We want to know the reasons behind why you choose one way/thing over another. Also, project suggestion : make a pc power supply into a bench power supply.

Is there a way to map a digital signal with arduino for instance I want to emulate a NZXT hue+ so what i have in mind is hook a adrino up inline with the hue+ read the digital output for the hue+ led controler and then use the recorded singnal to controle the led's.

GREATSCOTT! YOU SHOULD DEFINITELY MAKE A VIDEO EXPLAINING HOW TO BUILD A CIRCUIT, CODE, APP AND ZERO CROSSING CIRCUIT WHICH CAN CONTROL AT LEAST 5 AC LIGHT BULBS AND BE ABLE TO NOT ONLY TURN THEM ON/OFF BUT DIM EACH ONE OF THEM SEPARATELY VIA BLUETOOTH HC-06 AND ANDROID APP. THAT WILL BE A CHALLENGE!!!
