Invest some days in watching Dave’s videos - ALL of them if you wish - and learning about this lovely man. He’s a kind, witty and utterly brilliant man. He’s also a millionaire, and you don’t become a millionaire from being stupid (unless you perform a heist). Grow up, buffoons. --- End quote --- --- Quote from: eti on September 20, 2022, 03:34:52 pm ---A fact that seems to have escaped people here, due to being hyper-obsessed over his electronics theory... he's not claiming that this is an electronics tutorial - the LED is merely a means to and end, where that end is observing pin state. Also, SINCE it's not an electronics tutorial, maybe he's wise enough to have a pre-leaded LED with inbuilt dropper resistor... but then, I suppose looking at it from a logical perspective like this, doesn't give people the fury they so desire to deride him. He's no idiot. Only true idiots automatically assume all others are idiots. --- End quote --- Why is it ok for you to call us buffoons and idiots, and not ok for us to criticize Dave Plummer. Reverting to name calling makes you no better then the rest. |

As I mentioned earlier, when you're a noob following a step by step guide, you want uncertainties to be minimised because you don't have the experience to prioritise possible reasons why the blinky failed to work. As a noob, when it fails, you'l be questioning everything, including whether or not you blew up the LED or the GPIO because there wasn't a resistor. Why unnecessarily add that additional uncertainty? --- Quote --- not an ISO17025 procedure --- End quote --- That's quite some hyperbolic projection! I don't think anyone else is suggesting it is. As I already stated in my OP, I find Dave Plummer's videos interesting and I often learn things: he is, after all, an astute and experienced programmer, and we're of similar vintages. He can certainly run rings around me in his C# programming, although as systems programmers writing C and assembler we're probably on roughly level pegging. But he is a software guy. I do both software and hardware, I would never do a blinky tutorial without current limiting, usually a resistor: it's something I learned in 1976 when I was 11 when the vast majority of indicators were either neon or incandescent. |

How many do I need, what size, type, does it even matter? Oh god on eBay they only sell hundreds in a kit, I don't need that many jeez maybe I'll pass on this. There is value in making a piece of content as accessible and digestible as possible. Heaven forbid they blow something up and will have to engage with the community or dig deeper into why it didn't work. They might actually learn some troubleshooting too. It's fine, really. We don't need to be gatekeeping a hobby. |

If I was a beginner with not a lot of money to spend on my hobby, I would be very pissed if my 35 dollar board went poof because someone showed in a youtube video that it is ok to stick a LED directly on to the pins without explaining why it works for him. And here it seems to work, but what if it is for something more expensive and with bigger risk of going wrong, but hey it works for him, so it should work for me. It is about the principle. But that is youtube for you, it is so open there is no check on validity of what is shown, and that leads to chaos on some occasions. And that might be far fetched, but it is what is happening in this world with social media as is. People posting something on facebook about a party and others think it is an invite for them even they don't know the person in question. Happened in the Netherlands. Riots start due to things similar like this. Or people get killed because someone on youtube thought it was a good idea to post a video about doing some dangerous stunt, and people start mimicking it, not knowing what can go wrong. |

I'd far rather know I should be putting a resistor in than worry about whether I have a busted GPIO or LED. --- Quote ---How many do I need, what size, type, does it even matter? --- End quote --- Give a value, or a range of possible values, it's really not that hard. --- Quote ---Oh god on eBay they only sell hundreds in a kit, I don't need that many jeez maybe I'll pass on this. There is value in making a piece of content as accessible and digestible as possible. --- End quote --- If I could do this when I was eleven over 45 years ago, and I could only afford to buy resistors one at a time with pocket money when they were, in today's terms, $2 each, then I'd say that's hardly a chore. If you look at the other stuff Dave was using, like the breadboard, the Pi GPIO breakout board, and the LED itself, it's quite the stretch to suggest that a resistor is going to be a problem. Furthermore, IME the kits that include these GPIO breakout boards & breadboard also include a selection of LEDs and resistors, including 220 ohm resistors specifically designed to be used for LED current limiting. --- Quote ---Heaven forbid they blow something up and will have to engage with the community or dig deeper into why it didn't work. They might actually learn some troubleshooting too. --- End quote --- You seem to be contradicting yourself. You want it to be "accessible" so they're not put off, but at the same time you want them to "dig deeper". And when they do engage with the "community" I guarantee that the #1 answer is going to be "Where's your resistor?". --- Quote ---It's fine, really. We don't need to be gatekeeping a hobby. --- End quote --- That's quite a stretch, in anybody's book. If I could figure out that a resistor's needed when I was eleven, and purchase one, then I hardly think it's "gatekeeping". |
