Beginner concepts in electronics and Arduino

arduino_tutorial_series

[Jeremy] is all about the Arduino, but also into helping people get started working with electronics. He has put together a series of videos on his web site which discuss the basics of using an Arduino. Having just published his tenth tutorial, he dropped us a line to let us know. His videos cover a wide range of topics and include source code, schematics, and a full parts list to help you follow along with him.

While the core of his lessons focus specifically on how to use the Arduino to perform particular tasks, he does introduce the viewer to many different concepts along the way. He covers PWM, button debouncing, interrupts, SPI communications, analog inputs, and more – all of which are must-know topics that extend beyond the realm of experimenting with Arduinos.

The videos run anywhere from 6 to 20 minutes in length, so you will want to set a block of time aside if you plan on checking them out.

If Arduino-specific videos aren’t your thing, he also has a series of general tech-related videos on his site as well which may be of interest. Otherwise, stick around to see the latest in his series of tutorials.

    Not to be a troll but are we supposed to keep watching after he says “it is going to be much fun” without any facial expression whatsoever? The guy feels like a robot talking from beginning to the end. The videos sound like a great idea but at least they could have put a person with more charisma there..

    #MrXX
    Are you thinking in a person with two big charismas?

  3. wosser says:

    Charisma? Seriously? People with charisma have something called a “girlfriend”. Arduino users do not. Stands to reason.

    Charismatic guys will be making videos of an entirely different nature.

  4. wosser says:

    Fair-play to the guy though, he knows his stuff. No denying that.

  5. Jeremy Blum says:

    FYI – I have a girlfriend (http://www.jeremyblum.com/JandD.jpg).

    Also, I can be charismatic – it doesn’t always come across in tutorial videos I do, since I’m just trying to get the information conveyed clearly and directly. See this video for “charismatic Jeremy” – http://www.youtube.com/watch?v=7BJrYHfOCM0

    Charisma? it’s a tech video, it doesn’t NEED charisma. what it does need, it has: accuracy, clarity, and full explanation of his targeted goals, with proof of concept and design. I fully expect to see this one running his own million dollar company by the time he hits 30.

    And don’t be down on the ones with the intellect and the drive to use it. this kid is definitely going places (probably several times to the bank) and what would the girl who turned down bill gates in high school say now?

    “… and what would the girl who turned down bill gates in high school say now?”

    “Jesus, that guy still looks exactly the same.”

  8. you says:

    back off people, this is a guy that is showing one of his passions and obviously has much potential…not just sitting around trolling sites.

    as a charismatic male who is very interested in embedded computing (yes, i have a girlfriend, these tutes allow me an avenue to enhance my quest for knowledge in this subject…thx for the tutes jeremy!

  9. aztraph says:

    (ponders) Yup, probably. Good one Wes

    “Jesus, that guy still looks exactly the same.”

    Only if your concept of “same” implies he’s a few billions wealthier now

  11. Dave says:

    Great work, Jeremy. Share the knowledge.

  12. I would not have debounced the button in hardware, as it’s very easy to just implement a debouncing counter in the main loop, keyed off of the interrupt routine. If you are going to add hardware, show the correct hardware. Add a nice 1k or higher series resistor from the switch to uC input to protect against ESD, and a pull-up resistor of at least 10x greater than then ESD res to ensure the input goes low. You wouldn’t want to put a switch in parallel with a 10uF capacitor, because every time you press the button you are short-circuiting the cap through your switch… which is very hard on the cap and the switch. It’s not going to decay like shown… it’s going to immediately drop to 0V potential with a large current spike. The hex schmitt trigger is a waste of money and board space.

    Presented well, just work on the HW and SW details.

    Hey Jeremy, you two make a cute couple. keep up up the good work.

  14. Mick says:

    Jeremy, thank you for these! iv been a bit reluctant to get into programming (but i can build anything with my hands) and will prolly start now thanks to your videos. my first major project will prolly be a alarm clock as conventional ones dont have the features i want at a price i wana pay( but i will gladly pay double to make one). hey, its better then a blinking led. keep up the good work. btw people, its a programming tutorial, not a dating video

  15. Jeremy Blum says:

    1. Trolls make me LOL.
    2. Thanks to everybody who likes the videos. I’m glad I can provide materials that help people.

  16. Ekaj says:

    OK, no offense, but isn’t the “arduino” dumbed down enough already? I just feel like it might be better for people to figure these things out rather than follow a tutorial. A good percentage of the users don’t even understand how a microcontroller works (or in some cases, what it even is)…

    Jeremy, nice photoshop job with pasting the chick in the picture :D

  17. Derpamacthon says:

    hahahahahahaha,
    the trolls here are amazing.

    also, @Jeremy, good work, i’ve recently bought an arduino and going through it now, your videos have helped me tonnes, thanks!

  18. Ben says:

    @MrXX

    “Not to be a troll …”

    Good job.

  19. alan says:

    i admire what Jeremy has been able to do by the time he is 20. The sites hes ran, all the research he has done. It’s not going to be ANY problem for this kid to find a decent job. I’m pretty sure top companies will be fighting over him.

  20. Bill says:

    “Tutorial for Arduino”

    aka

    “Arduino Tutorial”

    So I guess the bully Arduino Lawyers wouldn’t back down over the name?

  21. uC says:

    @Jeremy Blum agreed!

    Don’t feed the trolls dag-na-bit!

    Arduino is a great gateway micro controller. Just because some of us know what a interrupt is and how to configure one on ten different micros doesn’t mean we were born with that talent.

    We’ve all got to start somewhere. I started with PICs because they were the easiest low hanging fruit at the time. Arduino would have been a much easier starting point.

  22. Ekaj says:

    I love how he had to “prove” that he had a “girlfriend” by posting a picture of himself with a chick. Insecurity is an ugly thing xD

  23. Niru says:

    You want Charisma? Try Carl Sagan. No. Strike that. Bill Nye. ‘k?

  24. j_jwalrus says:

    SWEEEET

  25. Jeremy Blum says:

    @Bill, I kept trying to contact them, and they wouldn’t get back to me, so I just figured I’d change the name and let it go. It wasn’t worth fussing over.

    @Everybody Thanks for the positive feedback! PS, I know that using a Schmitt trigger for this circuit is not obligatory, but I wanted to show it as a circuit component, and I wanted to invert the signal anyways so I could use the same code as before. Just trying to “mix it up” for the viewers.
