hi all
ive got an idea but im unsure how to go about it. i want to read air pressure and then display it on a oled screen.
im unsure where to start if someone has a suggestion or can point me in the right direction that would much appreciated
cheers

Very straightforward. What Arduino, screen and sensor do you have, and what have you done so far?
Should be easy enough. However less answers to:
Those questions need answered. How much air pressure? That determines your sensor. Which Arduino determines to some extent the needed code. This will go much, much better if you provide more information.

hi jremington
i have a uno wifi board and nothing else the pressure will range between 0-200psi as for the screen im not sure, are there better ones to look out for?
cheers

The first step is to get a pressure sensor and learn how to use it, with output on the serial monitor. There are plenty of tutorials on line.
Any screen will work to display numerical values, but if you want to make a graph, a small TFT display is fine (128x64 will work with the Uno). Adafruit sells several varieties.
awesome thanks jremington
Here is a tutorial for an I2C air pressure sensor (normally, I recommend to avoid Instructables, but this one is OK): https://www.instructables.com/M3200-Pressure-Transducer-Arduino/
There are many posts discussing how to read analog (0.5 to 4.5V) pressure sensors on this forum.
fantasic thanks for your help mate. is there a way that you could display say 4 readings on one screen?
cheers'

Never used an OLED display as of yet but if all you want is 4 rows and 20 columns is enough I have used plenty of LCD displays.
