Some Samsung smart fridges stopped working on Tuesday due to a firmware update.
Korean outlets were the first to report the problems, which affect Samsung’s Bespoke AI line of fridges. Star News Korea, per a Google-provided translation, said that most of the affected devices were four-door fridges from 2024 or later.
I think you don’t need microcontroller for that?
i think you do, for the counting and beeping.
No I don’t. I can use common door switch and a time relay for that, which triggers buzzer. It cost a lot more than microcontroller, but you can do it.
A timer circuit is cheaper than a microcontroller.
and why’d you do that when you can save money and get a microcontroller instead?
More reliable and the poster is wrong, it is cheaper.
That wasn’t the point. You said it cannot be done without microcontroller and I told you it can be done.
practically though, a microcontroller’d be better.
And you missed the point again. Congratulations.
nope… pretty sure they’re related.
Microcontrollers are cheaper then analog clocks
A 555 is $0.05
A NE555 runs out of sync very fast, so it is not that usable as a clock long term. If you want that you would need further components you don’t need for a paduk MCU which is like 3 cents
A 555 can keep time for the 1 minute needed before a fridge beeps that it has been left open. It’s not an alarm clock. It doesn’t matter if it is off by a few seconds.
Yes they are, but that wasn’t the point.
