Arduino Tutorial 18: Reading Numbers from the Serial Monitor

[@paulmcwhorter]

Guys if you are having trouble, make sure you have your serial monitor set to "No Line Ending". Otherwise you can get unpredictable results.

[@chuckpickering6040]

Good one there. I entered the code as you explained it, then paused the video before you executed it. My sketch compiled and loaded fine. It took me a while to figure out that I had to click Send or Enter to execute the read. I had the serial monitor set to "Both NL and CR", and the Serial Monitor would print an extra line saying "Your Number is 0"! Changing to "No Line Ending" fixed it. BTW, this lesson covered new stuff for me, had never seen Serial.available or Serial.parse before. Keep challenging us!

[@jeffstersmith]

omg this was my problem tytytytytytyty lol

[@Lisas4us]

Thank you Paul, you are a great teacher. I was wondering, the setting we had to choose was "No line ending", is it also possible to add a line ending. How would such look like?

[@stevewhite6168]

At last - this fixed my issue too. Many thanks

[@joecamp1372]

Thank you so much for mentioning this! I was pulling my hair out trying to figure out why my code wasn't working.

[@ahmedkhalifa1978]

The real reason for KZbin to begin with , is having a channel like this ! One of the best teachers I’ve ever seen

[@sanderromer6490]

Maybe you could mention that the Serial Monitor should be set to "No Line Ending" otherwise you will get an extra line/0 each time. Took me a while to figure that one out.:-)

[@diydad6723]

got me too, then i made the change👍

[@rtsempire]

Yes! Thank you, I literally just spent half an hour changing all sorts of code and trying to troubleshoot why I thought my While loop wasn't working properly.

[@Labattfartoui]

Huge thanks. I was hoping someone mentioned this in the comments, and it only cost me 2 minutes, not 2 hours of frustration.

[@jamescullins2709]

Paul, you are a very special person, teaching HS is not easy, and with your engineering knowledge you could make tons of money in the private sector, yet you chose to help these HS students get started in engineering. I hope they appreciate what you are giving them. Thank you very much, my God bless you greatly

[@augustvonmackensen9785]

I almost gave up on Arduino programming, then I came across this channel. Thank you sir !

[@ptsteln]

You're the first person who is actually able to teach this subject in a way that I can understand. Thank you very much for the content, I find myself writing and saving all the sketches you are teaching us and leaving comments on them as reminders where I went wrong so that when I refer back to them it helps fault find. I've made it to lesson 18 and I'm hooked!

[@jazibi786]

Same XD

[@missburgundy9444]

I absolutely enjoy your teaching method :) "Hold your breath", "Boom","Noo!". It really makes learning a lot fun, especially for a subject like this. I am so much thankful!

[@brucewoods9377]

purple_hat 54 yep, I hold my breath every time I compile, and I guess I get that “boom” moment every time it compiles without error, 🤣🤣it

[@TechFromDan]

the is funny

[@garyhart6028]

Yes I like that too. I have learned so much from Pauls video's, Ha video's! now I'm showing my age 😄

[@erwinvelasquez9018]

Watched videos up to this point, and it made me always wait for the "NOOOOO" as intentional mistake/blunder and the "BOOM" as eureka :) Good thing the sketch compiler only takes a few seconds to compile short codes, I don't want Paul to hold his breath long :) I'm a professional programmer and an electronics-hobbyist, and I'm having a great time learning through these videos on how to finally see my codes work on the physical world via arduino (and through these lessons). Thank you Paul McWhorter! I will be completing all your lessons here.

At the end you were right!

[@grahamovermyer5987]

I like putting in a fake processing loop with a message like "Processing...beep-beep-bop-boop..." just to give the little projects a little more life to them. I love this series so much and can't wait to start adding more sensors into our circuits!

[@daleredfern4472]

Just a tip for other viewers: I had an issue where serial monitor would ask how many blinks, I would enter, and it would work properly. But when it void looped, it would double prompt me with "How many blinks do you want?". The issue was my fault - you need to change the serial monitor from "Newline" to "No line ending" in the drop down menu next to baud rate, in the lower right-hand corner. This is something that Paul suggested many tutorials ago, but I didn't change until now. This guy knows his stuff so pay attention =)

[@chrysiwarner2129]

when i did change it to "no line ending" my code stopped working!!!! :D

[@filipegameiro4344]

I'm 52 years old and I'm learning a lot with your videos, they're easy to understand and I can already do some circuits. Please continue with the lessons. Thanks

[@michaeljenkins2345]

Mr McWhorter....just want to say, I am a farmer and a truck driver, but Ive always been kind of an amateur scientist & engineer. I havent had much formal education, but Ive been educating myself in many subjects for many years because its just what I love to do. Besides, a farmer has to wear many hats. Anyway, I want to thank you for doing what you do. Its a tremendous benefit to people like me :)

[@michaeljenkins2345]

The Arduino & Raspberry technologies have enormous potential in agricultural applications, and I hope to soon be putting them to use as much as possible

I had a semi colon ; at the end of my for loop and it caused it to only blink once. Took me half hour to figure it out. but once i removed it, the code ran fine. Loving these videos. The second coffee spill made me laugh out loud for real. You are such a great teacher Paul, I am enjoying every lesson.

[@DragonflyintheKitchen]

Mr. McWhorter, I just want to say thank you so much for these lessons. Not only am I having a blast learning something new, but you are brightening up a pretty dark time (i.e. social distancing, pandemic, etc). You make us laugh while you teach us programming, troubleshooting, and your love of ice coffee. :-)

[@geoffbird5650]

I am a retired elderly missionary surgeon from Australia, who has been recently introduced to Arduino. Learning to code is an entirely new experience, which I am enjoying . I am now up to lesson 20, but find I need to go back over the previous lessons to check my coding. It would be most helpful to be able to go to a particular lesson, perhaps at its conclusion, and view a single page of the complete code, rather than scroll through the lesson to find a particular entry. I join many others to commend your lessons, both technical and biblical.

[@AbdulRauf-le1el]

Another educative lesson from the great teacher. great work.

[@billcrow5403]

I had to stop the video several times. I was missing the closed bracket at the end. This is what I like so much is you (Paul) letting me figure it out sometimes. That's the way I learn! It's there and I missed it lol. Great video!

[@petersmet6860]

Paul, I am Peter from Belgium. I just retired. I can now focus on my hobbies. one of them is 3D printing! I have several projects that I want to combine with Arduino. Arduino is totally new to me. I had already bought a tutorial kit with accompanying book for beginners. It soon became unclear to me. Now with your way of teaching things are going much better so far. I understand the commands much better and all commands so far have all been successful. I also take notes with my own words to better understand everything. I know that there are now more than 60 lessons. You explain it all in great detail. Arduino and programming language is totally new to me, but at least at your pace I can follow it. The goal is to make my 3D projects work with external 12V or 24V power supplies. I think there's a lesson to be learned from this. But first through all the other wonderful lessons. Keep it up Paul!

[@JC-oz1wf]

Videos are just the right length. I really like the way you teach because it makes easier to remember what things to check over and over so the code would compile the first time I try it. I caught the "j=j+2" immediately while you were coding the example. However, I did not catch that you did not write the "pinMode" command, because my program compiled the first time. I keep making mental notes that if I need to use the pins, then I have to set it up first and then use it, so "pinMode" and "digitalWrite" or "analogWrite" commands always go together, no matter what. Thank you again for your time and dedication you put in these tutorials.

[@conniesocash1980]

This was a fun one (actually, they are all fun!) A bit more explanation on the Serial.available() command could be useful here, for example would I ever use it for anything other than this case of waiting on the user to enter a value. Also I'm curious if there is a way to have a user enter two or more unique inputs during the run. Maybe that is covered in subsequent lessons? Way to go on coding through the impediment of spilled coffee - handled like a pro! The important thing is it did NOT hit the Arduino! :D

[@laly0033]

You can do 2 or more inputs before anything happens. One example is using another subsequent While to wait for the 2nd input. I'm starting out on this coding stuff so can't suggest anything fancier.

Aside from forgetting my semicolon a couple of times I was successful with this tutorial. Another big thanks for all that you do.

[@ThermaRay]

Why did the LEDs work at all (albeit dimly) before you initialised the pin?

[@danthemancasey]

According to the Arduino reference; the internal pull-up resistor is enabled by default when pins are undeclared, and the resistor acts to limit the available current. Unfortunately the Atmega328 datasheet offers only basic schematic diagrams of the I/O pins so I'm unable to explain exactly how this happens.

Question: Why is if I input 9 ones 111111111 serial monitor shows a value of 27591?Just curious

[@tinnguyen1375]

maybe it is too large, overflow the capacity of arduino to handle a limited value of integer

[@hey0173]

U gotta put a double instead of an int

[@prabhakaranbaskar1400]

Hi you are employing 16 bit integer in the declaration. 2^16 = 65536. so when you input a number larger than 65535 it overflows and starts filling the register with the remaining value. Here, when you enter 111,111,111 its starts filling the register but it overflows, so it starts filling the register again but since your number is very large it repeats the process over and over again. 1495 times actually. After repeating it 1495 times it has a remainder of 27591. And thats the value it shows. 111,111,111 / 65536 = 1495.42100525 0.42100525 * 65536 = 27591 !!!!

Hi Pepsi, I had this same issue! After digging I found that in the Serial Monitor, you likely have it set to "new line" but should set it to "no line ending." This worked for me and should for you too if your code is written exactly like Paul's. Happy coding!

I realize that people who can keep up aren’t being held back. Said it before but I’ll say it again, sure wish this feature was available when I took my trade courses many years ago. Also, really learning the importance of entering the code correctly, 🤨 Hate it when your code works and I’m stuck for a while de-bugging. Seems like a lot to take in and if I were to comment, I need more assignments to do on my own to make sure I am getting it put in the grey matter, in large part because mine is extra grey. Thanks again Paul.

Wally Murray if Paul doesn't give homework on a lesson, then play around with the code and circuit so you will learn more about how it works or doesn't work.

Also tried the iced coffee, sorry but just can't do it. Need some heat in it. All the best for the new year. Rich

Idk how but your videos might be the funniest and most educational contents on youtube.

Hello professor Paul, this class was very good, I managed to do everything that was presented, pausing the video and making an effort to try to achieve it. I always hold my breath, I find it very funny, just like the numbers in the loop, hehe. Thank you for sharing this class with us.

Excellent!

I did catch those errors and was yelling at you (while still trying to hold my breath to, no avail), kids thought I was losing it...lol Tried pausing before the blinking section to figure out the coding, first instinct was the for loop but tried with while and got no where, played a few more seconds until I confirmed my for statement hypothesis re-paused and wrote it out with no further complications, barring the comma semi-colon debacle I also encountered at first. Lessons are surely paying off, Thank You.
