- Pick your Sunfounder kit up so you get the same results I do:
amzn.to/3SciApZ
You can pick up the neat jumper wires I showed in the video here:
amzn.to/3U2vyIe
You can pick up the diagonal cutters I show in my video here:
amzn.to/48xeaj7
You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this video I introduce you to the concept of using variables in your arduino programs. I show the variable types of int, float, char, and String. I show you how good engineering practice is to always use variables in your programs instead of constants. I will then give a homework assignment to see if you have grasped the concepts. Enjoy!

Still watching your arduino tutorial series from 4 years ago. Happy to see youre still teaching!
Thank you, professor, for continue making more videos!
Thank you Paul, the lessons are awesome!
Great video once again! Always waiting patiently for your videos! Thanks Paul
I had some issues with TH-cam. It refused to make a normal video and made a short. It is either shorter than 60 seconds or has a vertical aspect ratio. Here is what I did. Take the URL in your comment and replace the word "shorts" with "watch."
Good, patient instruction. I bet your kids loved you back in Texas!
Thanks Paul, another great tutorial.
Glad you enjoyed it
Finally wrote a function to do all the blinking (should have done it after the first blink). Here's the protoype: void blink(int numPin, int numblinks, int ontime, int offtime)
Hi Paul, Good video. In my C++ and Python programming class, we call your variable naming convention camelback.
Hey Paul, I sometimes use the edit option of "Replace in file" when I have a bunch of things to change in a file. Works good, but better to just use the variable from the start. It does come handy for other changes also. GREAT Video!
Thanx Paul
Thanks for this excellent lesson for beginners, Paul.
No homework from me this time but I'll make more of an effort next week. (I'm beginning to sound like Brian😁)
It would be cool to see the arguino R4 ether version with GRBL
Note that redLed and red_led are valid variable names. But, the hyphen is an operator in C and C++ and cannot be used in a variable name.
We are on Daylight Savings Time, so I will not be able to see this live any more as I have a standing appointment at this time. Pick it up this afternoon.
Hello from Belgium
Cool
Iam waiting
Sorry about missing the class this morning. i had a Doctor's appointment. Happy PI Day!
Oh no!
. . . _ _ _ . . . Thank you Paul.
Thank you so much sir for making tutorial about arduino can you please do more? Anyway i have a question about arduino chip sir, How to clear all the registry code in chip ? Do arduino chip has a limited storage for codes that we write? What if i upload an empty code well it help to restore the old state of the chip?. Thanks!!!!
Do you have an alternate way to donate like PayPal? Tried going the patreon route and got booted out.

Thanks!

@@paulmcwhorter just sent some , lmk if it comes through
My solution to lesson 8: th-cam.com/video/0opcxGW_Sps/w-d-xo.html. I know the videos is bad, I'm looking for better (and cheap/free) video editing tools.
LEGEND!
Hello, Sir Paul This is Unique from India idk if u do remember me I was the one eager to join your live but couldn't due to exams and I have been unable to get a r4 wifi kit shipped to India I have a Request to make can u request the sunflower kit company to also make the delivery available for kits in India too It is tremendously hard to find kits shipped here in India Please I humbly request You Sir to Recommend it to Them. Thank You love from India ❤
Yo Paul! How are thingz
Here is the homework for lesson 8. Link: th-cam.com/video/1_PPoMhPDYQ/w-d-xo.html
I had to slow the blinks. I’m a slow ham…..

Paul did a supplemental video on this.

great lesson again Paul, here is my lesson 8 homework :- th-cam.com/video/esY_4qL8LbE/w-d-xo.html. It includes homework video plus anther using Millis.

Homework assignment - th-cam.com/users/shortsI_OKt6JURNE Awesome straightforward training! I recommend this instruction to ALL! Paul, I need to know if you received this as my comments are never allowed to be publicly viewed... not sure if you can either. Please confirm by replying directly to this comment only. Thanks
I moderate all comments before they are posted to keep the comments family friendly, and polite. I review comments once a day, so might take one day for comments to appear. Hey, also please try to post your homeworks as normal youtube videos instead of shorts, as shorts are much harder to review, and dont allow comments.
@hftfire You video gave me a crick in the neck😺I think Lori said that if you film something using your phone sideways then it will appear the right way up on TH-cam and not as a short. I use a webcam which makes it much easier (especially as my phone does nothing except make phone calls and play snake).

My homework solution th-cam.com/video/_TBs26F1BTg/w-d-xo.htmlsi=Pqs0PhPtclUHoT5W In keeping with the theme of not having constants in the void loop, it took me a while to figure out how to eliminate using "0' in the "for loops".
