BMP OLED Servo

Hello, I'm not a programmer. So I'm looking for someone to write me a sketch.
Output is an Arduino Uno, a servo a BMP280 I2C and an OLED (SSD1306 Display I2C)

The OLED should display the air pressure and, as soon as a certain value is reached, the servo should do a movement of 90 degrees.

After that, nothing else has to happen.

Next to the sketch, I need to know how it has to be wired.
