You can scale that solution up and use external power supplies on LED strips if you want to control huge numbers of LEDs. You definitely need bigger transistors and probably heat syncs but it's still built basically the same way.

I think it would be much better, if people learn some stuff about basic electronic, before they start to use microcontrollers. Example, how is a diode working? How is a transistor working. What is the difference between PNP or NPN transistor ... ec. This would solve a lot frustration, i think.

These are great tips and agree Adafruit writes great code, drivers and documentation.

As for which board to use, I like the Nano, plugged into one of those development board things with all the extra pins. Then, depending on how many pins I need I'll try to get it on a pro mini just as a space saver. Good shout on the transistor to not overload the Arduino. And finally, yes, without Adafruit there would be a lot of head scratching.

I just noticed you were grabbing those sensors with a shock safe pair of tweezers. Nice. And I have watched this vid a gazillion times lol.

Hello Sir. I just wanted you to know that some of the equipment links are dead ends . . " Sorry can't find that page . . " on Amazon. Of the links I looked at I found Two were bad. The DMM4 and the Soldering Station 2 links. I didn't check all of them. Thank you for your post.

Great video :) My experience with Adafruit was less than stellar though. I wanted to return a tft that seemed to be dead on arrival. Their "customer service" finally got back to me 3 weeks in (not 3 days as the website states), and even then they wanted photos etc. etc. Ultimately I had to give up trying to return the display. I don't buy from Adafruit any longer.

Even if its old news and i knew all this tip - this is good video.

Hi Paul, I see a few comments here about ads during the video. I thought you must have somehow missed YT's autocratic implementation of mid-roll ads with creators offered opt-out only, but now I've seen you already made community posts and did in fact opt out. Have YT apologised or explained at all? Fran Blanche did a good video a couple of weeks ago on the YT "Adpocalypse". She often remarks that her "rant" videos aren't popular but I value the insight from content creators like you and her about the reality of working within YT. The algorithm doesn't even seem to have enough context sensitivity to insert in a natural break point. I've seen a few technical and instructive videos on other channels interrupted mid-word; it's clumsy and annoying to have to jump back right after a stupid ad which has only alienated me from the featured product or company. I like the tips in this video, especially about considering the device's current capacity and throttling back from its limits. I don't think most people realise how much drama is going on inside those tranquil looking components.

Bonus Tip ..... Always watch this channel

Thanks

Emitter follower is not a good configuration to show to beginners. Works as expected if collector and base voltage are same. And, for bipolar transistor, always use a resistor on the base, to protect Arduino if transistor go bad.

Please make video on TRIAC vs Relay

Would it be possible for you to show or describe an ARDUINO MKR WIFI 1010 charging/using a battery? I just cannot get it to work.

Loved the vid. So the signal line going to the base doesn’t care at all about the power consumption because that is being handled by the transistor?

Hi Paul, I have watched quite a few of your videos and find them to be generally pretty good. I have to say though, on this one, in tip number four, you have missed something. To show best practice, you should have had a resistor between the Arduino output and the transistor base to limit the base current. Although in this instance, it is unlikely to overload the Arduino or fry the transistor, it may not be the case for every transistor used. Other than that, a good solid video, nice one!!

I've been programming with PICAXE Microcontrollers for about 15 years but I recognize that Arduino is superior . I have Aspergers and I'm having a hard time moving to Arduino . Is there a way that I can Open up Libraries that other people have written to be able to learn how they work ? When I learned PicAxe Basic programming I just had a book and learned by myself from looking at example code and learning from that , but I don't know how to open up a Library in Arduino to see how it works , is that possible ? Yes I own some Arduino knock offs and I've gotten them to blink lights but nothing past that because I don't know how to use or load Libraries , but seriously , is there a way I can open Libraries to read their code to understand how they work ? Also Thanks alot for telling Us about Lady Ada's Libraries and Drivers for every thing , I buy from AdaFruit too and know of Lady Ada , Thanks , Take Care Man :)

Hi Kyle. A few years ago, when I tried to understand how specific third party libraries work, I did the following. (Using the Arduino IDE..) Let's suppose I want to understand what happens inside the debounce library. Create a new sketch, name it Debounce_lib. This will create a folder inside your sketch directory and a file inside it named Debounce_lib.ino In the sketch I would add a new tab for every (relevant) file belonging to the library. So here (for example) Debounce.h and Debounce.cpp. So now my sketch would have three tabs, and my folder has three files. I would then copy-paste the content of the original library files into the similarly named files of my sketch. You don't add anything to the Debounce_lib.ino tab, in fact I usually clear it out an make some notes in it. You never compile or upload this sketch, but you have the benefit of the colour highlights. I used to save those library sketches a bit separately from my actual projects because they don't compile. I found, if the libraries get more complicated with classes and subclasses and all kinds of fancy C++ stuff, the Arduino IDE is not ideal. I personally moved to PlatformIO as my IDE, where you can simply add the library into your sketch and modify and look at the libraries in the same way and at the same time. It is a little bit of a leaning curve if you are used to Arduino IDE, but the way you can trace dependencies and variables in other parts of the sketch is (in my opinion) well well well worth it.
