Arduino Tutorial 7: Understanding the Arduino Analog Write Command

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

In this lesson we see how we can write analog voltages using the arduino. We will demonstrate using an LED.

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

You can get more details on this lesson on our website here:

Best tutorials in the internet that really have the ability to teach you a new skill

I don't know how I managed to find your channel, but I'm extremely glad that I did

Where the hell were these classes when I was in school?? I would have actually been interested in going to school learning things like this.

Paul, I'm an avid (Python) programmer and sysadmin by day. I have had an arduino laying around forever, but it took a pandemic to find the time to mess with it. Thank you for these tutorials, they are excellent!

I appreciate you taking time to do these videos! I have PLC experience from manufacturing woodworking machinery, and I have retrofitted several cnc machine with mach3 and even helped beta test mach4. I also have a daughter with cerebral palsy that is 11. I used to tease her when she was 4. I'd ask her to go put wood in the furnace. She'd say I cannot, I'll get burnt or it's too heavy. One night she said that "if you will build me a robot I will". Ever since that night I have been dreaming of building a robot with her. Here we are watching your videos. Good Lord willing, we will be building our first test robot very soon. She is very excited and loves to write code that she has learnt so far. I'm very excited also!

Sorted this out for homework . I’m also 74 and had no idea of where or how to start. Your lessons are spot on step by step. I am beginning to learn how electronic components work and how to build a circuit that works.

Paul, I think these tutorials are awesome. I like that you are able to keep the interest of people of all ages. I also like how you explain everything in detail and not only how to do something, but WHY it is done. I'm onto the seventh video now and I believe I will be going through all of them. Thank you!

Thank you Paul for giving of your time and expertise. I ordered the kit that you are using, before I found your tutorials online. When I have a chance in the evenings I have started using your tutorials. Initially I was using the kit and last night I found Arduino TinkerCad which I used to do the homework. I can be in the living room with my wife, keep the mess down and do everything on the computer. My main focus is understanding what is happening which you make sure to include as well as develop coding skills to do practical projects.

Thank you so much, Paul! I've been trying to get into Arduino for the past week and trying to read through the badly written manuals and guides online. And I was honestly about ready to give up. I have no prior education in anything electronic or with coding.

But watching your videos on this so far have help me SO much, and actually given me confidence! So much that I actually started doing the homework you gave for this episode before you even mentioned it! I just finished up the last line of code whenever you assigned us to go through and change the brightness, and it just meant a lot to me that I already was confident enough to figure it out on my own and do it.

Please keep up the good work, and I can't wait to learn more! :)

Thank you!

Fantastic teacher. Taking us from what we know to what we need to know, step by step; really makes it easier to understand what is going on and diagnose problems ourselves. It's great that you've made intentional errors and even started programming how a beginner would with no variables and gone back to show how they make life easier and are an essential part of coding. Similarly pointing out that the circuit needs to be grounded before it is complete etc. The little touches like that are great. I can't skip over the theory lessons on electrons and binary, that I previously had minimal knowledge of. Without those I couldn't have worked out how to build the binary LED counter myself. Keep up the brilliant educational content sir. Many thanks.

[chrisnewsome]

I've been following your lessons and like your teaching style, concepts actually sink in to my grey matter. I successfully built the counter and programmed it without a hitch, it was pleasing that the programming was quite similar to yours. Thanks Paul.

I'm Loving this series man, you're videos getting me through this pandemic!!

[robertparker]

Followed through all your old courses and am finding the new courses a refreshing review and still picking up many new pointers. Thanks for the extra effort you put into these videos. Your homework assignments are a great touch.. keep it up. This senior citizen is enjoying the challenge.

[Zzt]

The HW assignments definitely help alot...I follow along with you and then when I do the assignments, I don't struggle too much because you explain everything very clearly. I am completely new to programming and these lessons are really great. Thank you!

Hello Paul, Once again, I did the homework and am just starting tutorial 7 - The binary counter to 31 was relatively easy, and I was able to create a "clean board" that looked neat and organized first shot, and the coding had no faults. Your audio is excellent, along with your teaching skills. I initially purchased a Vilros starter kit, and have recently added a GAR Monster Kit to my arsenal. (I will work toward being able to use the components appropriately, but looking at it gives me the desire to succeed enough to use the components in the GAR kit, however basics start with baby steps with an eye on the eventual prize package. Thank you so much for your tutorials, and your teaching skills.

[Ocelot]

I recently started learning arduino. Your explanations are the best I found on youtube. The way of talking and the dedication to make ideas clear really show that you are a teacher.
Thank you for taking the time and effort to put these together, they are very enjoyable.

[glennfelpel]

Your tutorials are definitely outstanding! My note book is growing. Even with the excellent way you present the material I still watch the videos at least twice. Good stuff and with the hands on experiences it brings it alive.

[thesimnut]

Amazed that I’m following this series and understanding it being my first venture into electronics and Arduino. Got setup for lesson 5 right first time, not bragging just pointing out how great and easy to follow your lessons are. So, thank you. Looking forward to completing the set

[Richardj]

Another one finished. I'm looking froward to doing all of your tutorials. Thank you.

[timothyrogers]

Fantastic set of videos so far, having great fun going through these tutorials with my kids. Whish you'd taught me at school in the 80's.
