That question is not new. There is a topic launched not long ago handling that question. Search for that!

Have to be cautious of instructables, however this one seems ok at first sight.

Hope it gets you started.

Note:- ....Just be aware that the 0.96" Oled can have supply pins reversed from that shown.
You will have to go with whichever one you purchase.
Also note the use of 3v3 Arduino and for the BMP280.
