Status Report:

- Pump control is OK
- Pump current measurement is OK
- Rotary encoder is OK
- Rotary encoder push button is OK (short and long push, doubleclick)
- Start, stop etc buttons are OK
- 1.5" OLED with graphics is OK

First test's done, my idea was to skip the pressure-sensor and use motor current, unfortunately that seems not to work with good enough accuracy. Also it's a bit unknown how big the current-difference is when pumping-resistance increases when tank is full.

So, I need to get another tank and maybe a bag. And hunt for the pressure-sensor begins.

If anyone knows any liquid pressure-sensors with 5VDC operating voltage and 0-5V range or I2C let me know.

But for now development is halted until more parts are here. At least I have time to make menu's etc

that sounds very good. have you ever looked at this?
