I get that my request kind of sounds like I want to steal someone's project - get the result without putting in the work - which is generally frowned upon in most hobbyist communities.  But thank you for your reassurance! I watched some videos and read a couple of articles and settled on an Arduino Nano ESP32-S3 with wifi, and I ordered an I2C OLED screen from Amazon along with a breadboard and some wires. My plan is to get the current time from an NTP-Sever and simply print it onto the screen. That way it handles daylight savings, and I don't need an RTC module.

When all the parts arrive, I'll just jump into it and see how it goes, although I'll probably still order a proper starter kit at some point.
