The Arduino HAL and the overall comfort of the Arduino IDE are genuinely valuable. I didn’t have to learn new flashing tools or a new debugging toolchain just to light a few LEDs, read some buttons, and emulate keypresses on a PC. The learning curve was basically zero.
I’ve worked with embedded systems before, and this level of simplicity is incredibly useful for people who just want to ship simple solutions to simple problems without fighting through vendor-specific, arcane tooling.
I've got some RP2350s since then with Micropython, now those might be even better for getting stuff done (without network or extreme low power needs)
Other reasons I'll reach for an Arduino over alternatives like ESP, RasPi (Linux or 2040/2350) include:
Simplicity. I very much ascribe to KISS. Having WiFi or Linux as part of my hardware _always_ leads me into scope creep. If the idea could be done on an AT328 (or similar), in my head it _needs_ to be.
Robustness. I probably have thrown out dozens of 3.3V microcontrollers/SOCs with dead io pins because I fucked up. An Arduino will often shrug off shorting 12V to an io pin (or even vcc) without blinking. RasPis seem to sometimes get damaged just because you looked sideways at them while thinking about 12V.
Experience. For me, the way I come up with project ideas seems to often be fundamentally linked with "knowing" how I'll do it on an Arduino. I've been using them over 20 years now, practically since they first appeared. And I'd been writing code for ATMega chips since a Burningman project in 1999, struggling with a cross compiling gcc toolchain. Arduino IDE was both instantly familiar, and such a breath of fresh air for me back then. It allowed me to easily experiment, and lowered my barrier of entry to random weekend or evening project ideas.
Separateness from work. I find the low level coding on a bare 8 bit microcontroller to be almost a completely different thing to coding for work. When work is going badly and I'm approaching burnout, any personal time Linux based coding for RasPis pretty much grinds to a halt. I'll find myself reading a book or doomscrolling social media instead of tinkering with that kind of project. The Arduino IDE is different enough to "work tools" that it doesnt get affected quite as
I have dozens of Arduinos that I will never use.
With a similarly priced (sometimes cheaper) platform like the amazing rp2040 / rp2350 which is roughly 100 times more powerful, I have no idea what the niche is for them any more.
The way they dropped the ball with their IDE is amazing. It still looks and feels like something that was rejected during beta testing in 1993
Arduino is following roughly the same trajectory as BlackBerry, with the current phase being "rapidly fading into obscurity"
I'd been using the Arduino.org version which had mostly driven me to use PlatformIO and ESPHome.
https://www.arduino.cc/en/software/#ide
Unfortunately, but perhaps fortuitously, I needed to use a Library only compatible with Arduino 3.0.0 which is incompatible with PlatformIO. That lead me to discover the Arduino.cc IDE which, while not on par with VSCode, is dramatically better than the Arduino.org IDE.
Why do you speak for everyone? I use my 2009 Arduino when I need something quick and simple.
They just want something that works, and ideally to keep using the same thing they've always used. They know what Arduino is, as long as it does the job they aren't interested in researching alternatives. They don't want to get involved in adapting someone's instructions for a different pin layout, or risk that anything they've done up to now stops working.
Yes, we all know it's a massively out of date platform easily outclassed by much cheaper and more flexible solutions, and if you must use the Arduino IDE it can build code for all sorts of boards. But for non-technical people by far the most important factor is to stick with something safe and known.
Indie devs who need testable builds might be a smaller market than tinkerers, but they're there.
It's a pain anticipating money flow into the future in more ways than one.
Would you mind elaborating more? I don't quite understand what you mean.
I semi-attribute this to my lack of willpower but perhaps arduino also isn't as tinker-epic as I thought it may be.
