I love the handwriting when you explain!

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

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

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 << ADPS2);" was offered at 6:47. What PS_16 should equal is "100" in binary and 'Great Scott' could have done just that directly using "byte PS_16 = 0b100". Why not? And no where does he describe the value of ADPS2. I have checked the Atmel AVR 328P manual (PDF) and have not found what I found using my own program to print its value: 10 BIN which 2 DEC. Maybe Atmel or C++ use the '2' in the bit label to mean the '10 BIN'. I have found this approach used else where in Arduino code as in WInterrupts.c; however, the novice would likely not know this as I didn't know and I am not a novice. This means that this statement: byte PS_16 = (1 << ADPS2); is equivalent to "byte PS_16 = (1 << 2);" which shifts left by 2 the '1' which sets PS_16 = 0b100 which is the desired value to use for a prescaler divisor of 16 in the ADCSRA register. ADCSRA is properly set using: " ADCSRA |= PS_16;" statement. Usually, I enjoy these videos but this one truly fails to teach the viewers. Arduino reference has good tutorial on bit math: 'Bit Math Tutorial by CosineKitty'; go there for a good background and write a sketch, too; this is how you will really learn how to manipulate bits.

Once he started playing Xs and Os at 6:00, that was the moment I knew I was destined for a career at Burger King.
@rikvdmark
This video series is definitely very useful! I'll be able to do a lot more due to a better understanding. Thanks!
@Tronex2009
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!
@PeterMedvesek
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 :)
@bettorapetto
I really like your videos because they are concise and force you to go deeper to understand the topic. Congratulations!
@willofirony
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.
@salutoitoi
It's interesting how you say that you are lazy and then you explain parts of atmega datasheet. Lazy for littles datasheet but ready for Atmega datasheet, like wtf haha :D
@TurbineResearch
Your handwriting is absolutely amazing
@BlackDawn
I don't get anything but i still watch
@danielpiotrowski1681
I am glad to see more advanced arduino topics. I would love to see more!
@cw41486
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.
@DamaKubu
Omg I didn't understand a thing back few months but now this is just what I needed. Love ya
@jairogon81
Lazy?!?! I somewhat understood it but I got to practice instead of just watching the video. Your a genius
@touhvang
part 4 next week? looking forward to learning everything about Arduino and what I can do with it. great video as always. keep it coming.
