I’ve never been able to stay focused with any other youtubers to be able to get through 20+ tutorials. Thanks man. Appreciate the lecture style, it feels like I’m in class.

@aaronmilliman7685 Рік тому

Agreed, want to be hyper focused, do the iced coffee BUT I put him on 1.5 speed. I'm forced to focus.

Also, the production quality of the new arduino lessons is really better. You really have the guts and energy to re-do the lessons. Bravo!

@emmanuelorilade2025 4 роки тому

You're legit the best teacher any student can have... Love you so much Sir

@dannycollins5698 Рік тому

I made a my buzzer play jingle bells🎄. The kids loved it. The wife...well...let's just say she made not have enjoyed hearing me get the timing correct for the jingle bells buzzer. 😄 It took me awhile to get the delays correct. The kids enjoyed getting to turn the potentiometer to get the song to play.

I love the way the lessons are arranged. This is like the start of a new chapter. Blessing from punta cana paul! Hope you come soon!

@barnabesambikibaroka5797 3 роки тому

Thanks paul for this lesson, i was able to make the buzzer sound according to the number of times i set in the serial monitor.. that was my personal assignment.

@ricklawitzky8311 2 роки тому

I made it. It was really fun. I added a LED too. Thank you for your great teaching!

I'm back to study some buzzer coding. Love the second part of the vid wher the difference in approach is shown between While and If statements.

@pradeepdube1398 Рік тому

Hey Paul, Thanks for the wonderful lesson. I used a combination of IF and ELSE function for this lesson instead of WHILE. Worked perfect.

I love you Paul you are a good man. You’ve taught me a lot.

@kishi8503 3 роки тому

Great idea doing the homework during the video. during your early videos there wasn't much to go on in terms of knowing if you did it correctly or not. It also allows people to grow a better level of understanding about the lessons you are trying to teach. Really well done to you Sir!!! From the U.K

@karelenmarritkruyswijk393 4 роки тому

Catched up after playing with rgb led and 3 potmeters to change colors. Thank you for this new lesson.

@tusharkumar7963 3 роки тому

Thank you so much sir! These tutorials are really helping me a lot! Who would even want to binge watch TV shows on Netflix when we have someone like you who is so entertaining and knowledgeable! You are the best teacher ever! Wish I could meet you some day :)

@tonyp4894 2 роки тому

Hi Paul. Thank you so much for these lessons. As a throwback to my old college days, I watch your lesson completely, just watch. Then, I do the setup and programming from memory with your video turned off. If I fail or get stuck, I sit and watch your video all over again, turn it off, and try to do the set up and programming from memory. If I can do the lesson from memory, I am confident that I learned the material. I am one third through your course, and anxious to learn more. Thank you, Tony

@ericsmith7988 3 роки тому

this was a fun lesson. I never clear my bread board so I still had my potentiometer and the RGB still hooked up. I used the Potentiometer and the RGB both come on when my volts went above my set number. I also wrote in to, flash and beep buzz above my set number. Thank you Paul always good lessons.

@svelocity2001 4 роки тому

Great lesson and thank you for challenging us with the homework! I do enjoy that. I had to go back to lesson 13 to remind myself of some of the coding but that's really good reinforcement. Also I did two IF statements one for >1000 and the other for

@johnellick7362 Рік тому

I added a red LED in series with the buzzer to add to the warning idea. I really enjoy the Arduino programs you teach. I bought my Arduino Super Starter Kit and have been following along with all your project lessons.3 years later you are still teaching someone. I'm 59 years old and feel like I'm back in Vocational School for electrical engineering classes. lol

Another excellent tutorial. I started off using the while loop...though initially I forgot to set the buzzer low outside of the loop and my dog was not happy.

@MehrdadShirazi007 3 роки тому

I also like to thank you for all the good work you're doing and tell you something funny, I was looking for a way to get all of the kids in the family like niece and nephews busy with something other than playing games on iPad all day since the stupid virus started. So I started a class at home playing your videos for them LOL my favorite thing about your videos is the homework at the end keep up the good work.

@richardstewart4135 3 роки тому

Another great lesson!! For some reason I had a bit more difficulty getting the program to run correctly. Must have been getting tired because my syntax was sloppy. The last one took me forever as I substituted a comma for a period and just couldnt see it. Kept getting the "Audrino failed to compile" error. LOL. All good now. Thank you for the lesson and again, I am looking forward to the next one.

Thankfully, i finally found some where in Australia to get your elegoo starter kit. By the time i get one from Amazon would be double the price with postage and currency conversion, so been using Arduino starter kit which is a bit different with the items. So was having a few problems but I will be right shortly, and thanks for the videos they are great.

@timmcdonald9182 3 роки тому

Thank you Sir for taking the time to put out these awesome tutorials. You remind me of my old professor Jerry Cage (electrical engineer) may he rest in peace. I achieved an advanced manufacturing degree but before I can go back for more PLC training he passed away. I definitely need to keep up on Allen Bradley and Siemens coding/remembering relay and ladder logic. Are you familiar with plc's? If so please comment back if you have time. Thanks again.

Hi Paul! Hey, great vids. Thank you so much for taking the time in posting these lessons. I started at number 1 and up to this one now. I want to apologize... at one of the times I was supposed to hold my breath, I coughed and caused your project to not work momentarily. Oh, repost your address so that I may send you a couple of Kuereg pods. I drink Peet's Major Dickason's; it's a bit better than Starbuck's. :-)

@danny12345 4 роки тому

Paul thank you

@RavensHammer00 Рік тому

Very nice! You made me trouble shoot my coding, so I did this with two "if" statements, and a "while" statement. I think the "if" variant was simpler, and didn't need another serial.print and analog.read statement in the loop. I was wondering why the serial print stopped when it reached >1000, and I was able to figure out "while" created an endless loop without the analog read. Thank you so much for the instruction, it's really making me think about the logic behind the code!

@abdelhassibdad3413 4 роки тому

you are the best PAUL

@jadersoares3659 7 місяців тому

Dear teacher, I improved the project by adding a red LED that flashes at the same time as the buzzer sounds, it looks really cool. God bless you.

@fablapp 2 роки тому

hi prof, nice content again, things start to combine. Still prefer the if statement however if I have to be honest!

@EdwardRLyons 3 роки тому

I used the If ... else method for this (If >1000 buzz, else don't buzz). That way you don't have to duplicate the analogRead(potPin) and Serial.print(potVal) statements. That's one way If ... else can be better than a while loop. This is a great series of tutorials. I've learned so much in the last several days. Thank you from Ireland!

@mathewwagner168 3 роки тому

as did I, saves the redundancy. if (potVal>=1000){ digitalWrite(buzzPin,HIGH);} if (potVal

@douglasmckinley-sr1507 2 роки тому

Great explanation of the pros and cons of the "active" vs "passive" buzzers. Was curious what the "Remove Seal After Washing" sticker was all about. Found this explanation, "Many processes use "no-clean" flux today and you can remove the sticker after manufacture. Others use water soluble flux and wash the finished assembled boards in what are basically dish washers."

@georgesinclair9551 4 роки тому

Great video and tutorial Paul. Just a little observation, hope you don't mind if I say, you mentioned that's it's good programming practice to use variables and to get into the habit to use them (I agree 100% with you). You created the variable dt for the delay time, but you didn't use it if I'm not mistaken. You continued to use the value 2000 in the delay() function !! A slight oversight I think !! Keep up the good work though and sorry to be so pedantic.

@markharrisllb 3 роки тому

I really struggled with this one. It took my code and the print screen to gave a read out but I couldn’t get the buzzer to work. I checked the buzzer and even the Arduino with another but it wouldn't buzz. In the end I started again and it worked but I still don’t know what I did wrong. I really wish I’d saved the first setup to compare. One of my better ways of learning is through my mistakes. Thanks to your approach I’ve not put this much effort into learning something new since my law degree. I hope your high school students appreciate how lucky they are.

Hi Paul! I did the assignment using an if-else statement and then watched your version using a while statement. Can you explain the advantages/disadvantages of using one vs the other?

@larrygohl2816 4 роки тому

This is a Great tutorial on using Arduino for a beginner like my self. Only one thing I miss in your tutorial was on COM PORT setting. Got the port setup on the right USB, and the right Baud Rate of 9600 , but I did find out that the line feed has to be in "no line ending" to work correctly. That little set back made me go thru my program looking for my error in code . Looking for all the info i could find on WHILE statement thinking i had something wrong. It was my son that saw my mistake and showed me how to fix it. SO FOR YOU BEGINNER MAKE SURE YOU ARE ON "no line ending" IN YOUR COM PORT,

@colepdx187 4 роки тому

So I started the day looking at my remote sensor monitor blinking its lcd backlight as a way to draw my attention to an event that occurred and thought to myself, "what I need is a buzzer in case I'm not paying attention to the display." I knew I had both an active and a passive buzzer in my 'most excellent' Elegoo super-starter-kit and was speculating (correctly as it turns out) about how they function. Then I get this UKposts notification about a new tutorial on using an active buzzer with Arduino. It's almost like someone was reading my mind. Eerie. I don't suppose you're next tutorial is going to be on energy-harvesting to power our Arduino project? No? ---read my mind---read my mind--- Thanks Mr. McWhorter. Your timing today was serendipitous.

@carlos2004 4 роки тому

i have found it very convenient to wire a red LED (with resistor on the LED, of course) on the buzzer pin. the output pin goes to the positive on both, but they each get their individual ground. like this, you have both, a visual and auditory cue, but when you are troubleshooting, you can disconnect the ground from the buzzer leaving only the LED as to not have the annoying sound of the buzzer constantly blaring. in the final build, they could share the ground.
