I want to build something simple but have no idea how
I‘m completly new to this. All I know is that an esp32 might be the way to do it.
The project is:
I want to make a physical reminder badge. You program it to turn on a led at a certain date / time or every x days / hours minutes. If you push a button it resets the cycle or turns it off, when it was a specific date.
In its final state it suppose to look like a round button that you put on a e.g. cat toilet to remind you it‘s about time to clean it.
It‘s a simple „in the real world“ reminder that you can‘t ignore as easily as a push notification on your phone.
How would I do that?! What would I buy?
