First off, yes, I'm a "noob". Second, yes, it's for a beer project.
So 95% of the people asking questions here? Make that 96% now!
For some reason I can't seem to find what I'm looking for...variations of such, but not the same.
[u]Scope[/u]: Trying to measure the amount of beer (in Litres) left in my keg. [u]Material[/u]: I'm using an [u]in-line flow sensor[/u], an Arduino Uno R3, and a 2x16 OLED display.
[u]The Idea[/u]: I know a full keg is 19L, therefore as the pulses come from the sensor, it decrements from 20L until it reaches 0. The OLED display would show both a percentage remaining (%) and a "Fuel gauge" style bar reading, therefore visually showing the amount remaining. A reset button would reset the unit to 19L (so 100%) and the bar would return to full.
[u]Extra[/u]: Thinking ahead, should the Arduino unplug/power go out, the unit would reset, therefore it would be nice to either have the information saved, or a dial to manually set the amount remaining.
Some people have weighed their keg etc...but I think the flow sensor provides a lot more potential.
I've tried a simple flow sensor code to familiarize myself, and I can also build the circuits, the more complex coding here is where I'm lost.
Any help would be greatly appreciated...maybe I can mail you some beer in return??
