Arduino Tutorial 14: Dimmable LED Project

You guys can help me out over at Patreon, and that will keep this high quality content coming:

In this lesson we take you step by step through an Arduino project where we create a dimmable LED. This will take advantage of the commands and circuit expertise we developed in the earlier lessons.

You can get the following Elegoo kit, to follow these lessons and play along at home

Get more details of this lesson, and great arduino content on our web site HERE:

Not talking to a wall.  Actually watched the entire video.  Good job again, Paul.  Thanks.  Love your series.

When i bought arduino i couldnt even turn on an LED. Thanks to you Paul i now can do everything you taught me.
P. S im 13 years old

I'm a10 years old and when you said linear equation I was going to quit but you explained very vell that I little bit understood what is linear equation thanks for such tutorials

I have ADHD and getting started seemed very daunting until I found your videos - I'm following along, doing all the homework & trying stuff out when I finish. It's a lot of fun. Thank you!

[bersrk_burgr]

Lessons are great! As someone who loves to completely understand why things do what they do I really appreciate you going through the math on this instead of just saying "Put these numbers in and it'll work". Keep up the great work and I'm having so much fun learning how to do this!

I got my Arduino only five days ago but learned already about dimmable LEDs. What a great lesson! Love the integration of circuit design, math and coding. Wish this kind of educational stuff was available when I grew up. It gives me confidence that our grandchildren won't have to plow through boring electronic books. I think when I am done with all your tutorials (hopefully by the end of the summer), you will succeed in getting me "to think like an engineer". As the Chinese say: 活到老学到老, never too late to learn. I am 74.

Paul, your videos are amazing, and you are a great teacher! I’m a chemical engineer, but never did match with electrical or coding until my current job. I’m now doing plc programming and wiring up level and pressure, transmitters, et cetera, There isn’t much good information on the Internet in terms of basic instruction. My son as a freshman electrical engineering student and had a semester project based on the Arduino last year. After watching what he was doing, and realising how similar it is to PLCs, I bought a kit and started playing around with it just to get more familiar with electrical and coding. Then I found your tutorials. You have a great mix of immediate hands-on instruction, but with the math and physics mixed in. I find most tutorials limited in value because they mostly just do the hands-on part. So far your progression of skills has been spot-on.

Thank you Paul, you are a great teacher, being a former Instructor in electronic technology for 13 years, and understanding how valuable it is for a student to have the lessons broken down practically and with examples, it allows me to recognize the quality in your instruction!

Hi Paul! I was a 13 year old teen bored at home this summer in quarantine ... I randomly found your videos one day and instantly had to get an arduino super starter kit. Trust me you are not talking to a wall at all. I 100% consider you a teacher and more, always making sure to do that homework! Thanks for giving me and many others something fun and exciting to do this summer :).

[rawadhasan]

Paul, you're a great teacher. You're not talking to a wall. I'm actually learning practical engineering from you. I'm an aerospace engineering major and hope to learn more about electronics from your series. Honestly, you made my day when you said, "I want to teach you engineering." Thanks a lot for your effort!

[richardmonseglio]

I am an electrical engineering student and have learned more watching your videos than I have attending classes, so please keep up the good work.

[juergenfoterek]

Good that you explain the Math and not only showing the Map function. So anybody knows more what the Arduino is doing in the background when useing the map function..

[ethanwright]

You are not talking just to talk. I watch the full video and do the homework assignments you give out. This series has been really helpful and I appreciate all the work and time you put into it.

[laxmanrao]

The point you made from 6 mins 30 seconds onward is what i feel makes you stand apart from other and a great teacher. To understand something truly we should know it's building blocks, now there might be a short cut to get to an end result but leaning on short cuts doesn't help in doing something substantial in any field. Thank you Sir, your videos are helping many a guys like us learn amazing things! ❤️👍

[donthomas]

i do the projects, and the homework. I love where you have taken the series. Occasionally I do find myself yelling at the screen when i see a mistake lol, but you always catch them and usually before I do. Great job thank you for your hardwork!!!!

I'm an old guy (69) who studied electronics when vacuum tubes were in vogue. (long time ago.) I built my first digital circuit with simple switching transistors, capacitors, resisters etc. My first chip experience was with the NE555. (also a long time ago) I'm studying along with you and am on project 144 as I write this. I am fascinated with micro processors and their uses in hobby projects. You asked if anyone was out there? YES! I'm here. I've programmed some in BASC but this is really quite different. (to me) I enjoy the course and am committed to the end. Thanks for producing it.

[SerialCommenter]

These lessons went in just the way I was hoping! Right as the potentiometer was introduced, I had the same idea.

[thamesidersmrg]

I'm 72 and did a little programming in my late teens early 20's. The language has changed principles of programming exactly the same. Well done for clarity of explanation. Have also completed your homework

[amanmakwana]

YES, YOU ARE ACTUALLY HELPING ME TO LEARN THIS VERY ACTIVELY!

[chrisosborn]

Great lectures Paul. They are better than all of my Arduino books put together. I'll stick with you and do all of the projects. I'm 73 and a retired engineer (UK) but have always struggled with digital electronics. Regards.
