Great video! As to your assignment: If we''re defining a blink as definitively being on and off, about 40-ish ms was where it still 'blinked' - 20-40 ish ms was more of a strobe, and getting closer to 10 ms was when the delay started to be imperceptible.

I wish I had you for a math teacher back in school. You stress the fundamentals of learning Math and not just a quick solution with no explanation. Thank you!

Cool tutorial, brother.

Great video, simple but elegant using the low pass filter

Sorry Paul, I was drinking my hot coffee. So I couldn't hold my breath.

Paul, I have referred your website to people I know they will benefit greatly from it.

Paul, Thanks for the outstanding lesson. I am better off for it but my Neopixel is a casualty of this lesson I blew it, but my Raspberry Pi survived, I cheched it with other programs. : (

Can you make the course on esp32, Because your lessons are too good

Second try at the homework is on my YT channel. The first version worked fine for a 12 pixel ring but glitched on my 60 pixel strip. I had to change from storing pixel data in a list to using the array module. I show why the array is better.

Another great lesson Paul. Lesson 92 Homework is on my channel. Can't wait to learn how to use more than 1 pushbutton. Thanks.

Yes!!! Now I get to see if my S.O.S. was correct. About 80% sure I got everything right. I know the three dots, three dashes and three more dots is the pattern but probably missed a semicolon. I only wrote the program cause my Arduino has been delayed due to the weather. * Also, When I type out in all caps (13,OUTPUT) the word OUTPUT isn’t happy and doesn’t turn blue. Any idea why it isn’t?

I was a little confused at why you decided to pick the particular diagrams/model to teach this concept, but I realized by the end of the video that you are a pretty good teacher. I learned about electronegativity back in high-school chemistry, so I was jumping ahead logically but I get that this is a quick way to teach the concept to beginners. Is this a standard model? I figure that it is considering the acronym you used to describe the recombination.

Thank you for the video. When I used tempC=sensor.temperature() I received the following error: TypeError: 'float' object isn't callable. WhenI changed it to tempC=sensor.temperature it worked. Did anyone else have this trouble? Anyone know why it would work for him but not me?

You just gotta love this guy and his ability to teach!! I'm 5 years late to the party and so happy I found this channel. I love the way he explains things, I love the way he sometimes makes mistakes on purpose to show how things can be done in a propper way and I really love the homework assignments. Over all just a great guy. And he completely took away my concerns whether I should get into this kind of science/magic or not. Which to me is a great factor and I'm absolutely gratefull for all the work, passion and fun he puts into this topic!! Thank you so much!! 😌👌

Love your lessons excellent. Wish I had a teacher like you when I was at school I am now 63. I would really like you to do a MOSFET video all the best John from the UK.

Indigo protects you like you protect us from burning down our arduino.

Hi streamers i am watching this video right now

Im 🙅🙅🙅🙅

Great Lesson.

Having so much fun with this, I've been a professional software engineer for most of my life but I feel like a small child again discovering the world of electronics <3 I can no longer see the LED blinking at 10ms. It's close at 11ms but I still see faint flickering.

Hello, I am sharing my solution to the exercise from lesson 6 : kzbin.info/www/bejne/r6rJZoZ_rserqKs

20 miliseconds btw love this series

Don't change anything about how you demonstrate or explain the physics, it is exactly right.

If you turn the power supply module off, the TA6586 motor driver chip doesn't have power, yet the Arduino may be either driving the BI and FI inputs high or pulsing them with a PWM. Is there any concern about harming the TA6586 or are they built to withstand that?

Dear Professor, I am a 72-year-old retired individual who has recently finished my first 20 sessions of learning Python. I found your lessons to be enlightening, enjoyable, frustrating, and entertaining while I was learning. But I didn’t do it just to find something else to watch than cats. (To tell the truth, I didn’t even know people did that until you said it. But I followed up with a search on the internet to find that cats were the most popular subject on KZbin.) I began your series on Python after you suggested I needed an understanding of Python to understand your series on AI. But I am wondering if I need to continue deeper and follow you deeper into Python in your next sessions on graphics in Python. Or if I know enough to return to learning about AI. It's not that I don't find the prospect of drawing 3D objects with a programming language appealing; it's just that I don't plan to pursue it as a career. I just wanted a foundation from which I could understand AI. I don’t want to bore you with my life story, which, as they say in the movies, is complicated (and convoluted), but recently I began interacting with ChatGPT to understand AI. I pushed, challenged, and used it. ChatGPT finally suggested that if I wanted a deeper understanding, I should go to the AI websites. I followed ChatGPT's advice and discovered that I had no idea what the websites were discussing. This discovery led me to your AI series, which in turn led me to your Python series. I was wondering if, instead of continuing on the endless path of learning, it would be a good idea to turn back and revisit the AI series. I have thoroughly enjoyed the process of learning Python. For two years, more than forty years ago, I did some basic programming in COBOL to manipulate data for analysis in SPSS, SAS, and BMDP. This was my area of expertise at the time, but I abandoned it to pursue other career paths. The last lesson on threads was the most exciting of all; having started programming with computer cards, I deeply appreciate the ability to run two processes at the same time. It reminds me of my early days when I discovered that I could accomplish tasks that required 200 statements in SPSS with just 7 statements in FORTRAN. ‘Appreciate’ is too weak of a word. I was amazed and excited by the possibilities. However, from a practical standpoint, I believe it's time for me to return to your AI course. I am 72. The clock is ticking, and my mental abilities, like the rest of my body, are fading. So, that is the purpose of this long note, which, if you have read, I hope you will answer. Have I gone far enough in Python to continue learning about AI?

really enjoying your tutorials. i am a retired MD of a controls software and hardware company and wanted to learn about this stuff

So I learned Arduino with Paul who is a good teacher

10:21 Sorry Paul, It was me.

this was quite clear

kzbin.info9zOtWyGwIAA Homework lesson 53 Ultrasonic sensor measuring the distance to target with a pushbutton and print it to Oled display.

thanks Paul

you could put the button over the trench to have space no ? great video by the way, I started watching these a month ago and I love how you explain things.

Piece of Cake!! Thanks so much for another great lesson.

extra long video

Great video like always. I self-learned about this OLED last week. I like to reassign the OLED reset pin to another open pin. Assigning the OLED reset pin to -1 will cause your reset button not to work on the Arduino. I found these helpful websites to create your own pixel/animation for the OLED but I can't post them

kzbin.info30ParZOw1BU *** I changed the original Video and slowed down the Pulse a bit and added anti static bags to tone down the Brightness.... **** Here you Go.. I used the getRGB library we made in Lesson 55 and got it to work in the State Machine... the Colors are Gorgeous.

This is a great video series and I absolutely agree with the emphasis on how important it is to try to be the hardest working person in the room. I think that the drive to go above and beyond through hard work is probably the most important determining factor that separates engineers. From my own personal experience, in high school I wasn't the most focused student academically (which I definitely had to make up for in college). However, a deep passion for sports honed my ability to work hard and inspired a competitive spirit within me. The intangible lessons learned through the competitive and unforgiving world of athletics helped me overcome the lack of technical knowledge as an incoming engineering student. Thank goodness my grades in high school were decent enough to get me started in engineering classes!

Amazing

Did it. kzbin.info/www/bejne/gmTYhqeBhZdoerM

So I did it alone, but : 1. I added a function to power off my led, because why not (press both buttons at the same time) 2. I used pull down-resistors 3. I used a map func because I wanted to try it. 4. I used a passive buzzer to match the tone with the light brightness Here's my code : const int buttonPowerUp=5; const int buttonPowerDown=6; const int pinLed=9; const int timer=250; const int buzzPin=3; int ledValue=127; int delayValue; bool buttonPowerUpState=0; bool buttonPowerDownState=0; bool ledState=1; void setup() { pinMode(buttonPowerUp, INPUT); pinMode(buttonPowerDown, INPUT); pinMode(pinLed, OUTPUT); pinMode(buzzPin, OUTPUT); Serial.begin(115200); analogWrite(pinLed,ledValue); } void buzzOn(int delayValue){ digitalWrite(buzzPin, HIGH); delayMicroseconds(delayValue); digitalWrite(buzzPin, LOW); delayMicroseconds(delayValue); } void loop() { buttonPowerUpState=digitalRead(buttonPowerUp); buttonPowerDownState=digitalRead(buttonPowerDown); if(buttonPowerDownState == 1 && buttonPowerUpState == 1){ ledState=!ledState; digitalWrite(pinLed, ledState); delay(250); } if(ledState==0){ analogWrite(pinLed,0); } else{ if(buttonPowerUpState == 1 && ledValue <= 254){ ledValue++; delayValue=map(ledValue,0,255,5000,5); analogWrite(pinLed,ledValue); buzzOn(delayValue); } if(buttonPowerDownState == 1 && ledValue >= 1){ ledValue--; delayValue=map(ledValue,0,255,5000,5); analogWrite(pinLed,ledValue); buzzOn(delayValue); } } Serial.print("Power Up : "); Serial.println(buttonPowerUpState); Serial.print("Power Down : "); Serial.println(buttonPowerDownState); Serial.print("Led Value : "); Serial.println(ledValue); Serial.print("Led State : "); Serial.println(ledState); Serial.println("-----------------"); }

I now understand how to go through the data thanks Paul 😀

I’m pretty sure I sketched S.O.S. Accurate to how my brain feels after watching the tutorial about how LED’s work. Thanks man.

thank u sir

For the homework, my program is having trouble with reading the value from the potentiometer. It’s hooked up to the 5V pin, A2 and ground. When I get a value, it’s is only hovering around 250 and turning the potentiometer doesn’t change it at all. When I tried the same setup on the wokwi simulator though, it worked. Is this a potentiometer issue or an issue with my arduino WiFi? Any help is appreciated 🙏

Long Video- wow.

Came from sketchup after realising it was fairly useless for 3d printing and cad. Tried blender and thought my journey was coiming to an end. So glad I found you. Awesome series upto now.

Mr. McWhorter, I can't thank you enough for this series. I'm currently doing my ECE undergrad and I'd never learn what you're teaching in my curriculum. I think this series is useful to anyone in any career too.

What has happened with the live chat?

Good morning Paul how are you ?

WTF
