Step by step build - due to $$$

I am eager to start building a kegbot but due to financial constraints I cannot buy and build all at once

I would like to start by using RFID with limits per person using water for a start

I would say I am technically savvy and can follow instructions well

could someone please point me in the right direction

PS:I have read through the whole site but I am confused

Did you ever get an answer to this? I had the same frustrations as you and just got mine up and running today… Kinda… the last step is to attach my flow meters to the Arduino but the Arduino is registering and using the test pins it is recording pours!..

I would be happy to help.
