Hey Sudo Room!
I'm in search of some suggestions, I'd like to build something that
would give me a visual cue for when to water my plants (I have other
similar needs as well, all related to how bad my memory is😂). You
could say I could set an alarm on my phone, but I'd like to set a tiny
display near my plants, that would go red when it's time to water my
plants and green when I reset it after watering my plants. Probably
need to code it to go red after 3 days or so.
Need something small, I thought maybe this MicroBit can be a good option
https://microbit.org/
Do we have one of these available at SudoRoom by chance?
Anyways, open to other ideas as well before I commit to that!

I got a bunch of soil moisture sensors on aliexpress a while back and i
haven't tried them yet, you're welcome to a few of them! That way you're
measuring the soil and alerting according to that.
If you're alerting based on a routine, it can be just a timer that you
reset? You could use a 555 timer chip which we have several of at
sudoroom. I guess if you wanted it to be a matter of days then there would
need to be a counter involved.
We have lots of different kinds of LEDs which could be the visual
indicators. We also have a bunch of simple microcontrollers like the
ATTINY25 which can be programmed (with arduino even) to do a simple amount
of time and then light the LED, or even do a blinking pattern that gets
more elaborate the more time goes by.
Let me know if I can help with any of this!
