User Manual Version 2 6 62 The objective of the project described in this manual is the mashing schedule and process automation for all grain beer production with a single vessel BIAB RIMS system Open Ardbir is largely inspired by the original project formerly Braudino by Stephen Mathison and then further upgraded and modified by Mike Wilson under the Mike s Brewery appellation The micro controller Arduino Uno is like in the original project at the core of the automation process and can be used in both a fully automatic or manual mode The controller automates all the phases from mashing in the grain to boiling the wort this includes any required hop additions The controller delivers all these capabilities in a simple easy to follow and logical manner for beginner and advanced home brewers alike The system interacts and can be programmed via 4 Push Buttons and an LCD feeds back all the relevant information the user needs in all the phases whether used while setting or running the system The Original Braudino shield was developed in order to connect a Temperature Probe SSR relay for controlling a heating element Pump Relay Signal Buzzer along with the LCD display and 4 Push Buttons This original shield is what has been referred to above as having been modified and upgraded by Mike Wilson From a HW perspective the code should be adapted in order to support the correct LCD display 16x2 or 20x4 This op
