Hello,
there is also a possibility to measure the depth and temp:
http://docs.bluerobotics.com/bar30/
but i think thats too much for the little trinket pro.

I 'll go with the small OLED, becours i want to have it on the front of my chest O2 rebreather. SO its in the near of my face. And the display is fine readable inbetween 50cm-1m

Hello,
I made a new display layout so it is better to read.
[video=youtube;wyRUA5IXyf8]https://www.youtube.com/watch?v=wyRUA5IXyf8[/video]
In the top left corner there will be shown the depth (when my depthsensor arrives: https://www.bluerobotics.com/store/electronics/bar30-sensor-r1/ )
In the top right corner is the battery voltage displayed.
Down three sensor readings. Only the first is connected and calibrated with 100% O²
The small numbers to the right of the sensor readings are the mV of the sensors. (Only the first is connected)
Calibration with 100% made my sensor readings more constant.
On the right site there is the Bottom timer. Starts when the whole thing is powered on. It counts the "h", "min", "sec" from top to bottom.
there are still a few things to do...
I'm considering between a simple on/off switch and arduino sleep code...
regards
anton
