The LCD key/switch breakout panel is working like a champ during my bench testing. This board breaks out 5 ports for the HLT, MLT, BK, Pump 1, and Pump 2 LCD keys. It also provides connections for the switches and dials for those same items. A 12VDC to 24VDC step up converter (blue board) provides power to turn the contactor on in the power control box. This 24V output is controlled by the black relay to the right which requires the following to be turned on:
1. All element/pump control switches are in Off position to initially energize (my safe start feature)
2. The emergency stop is not activated.

The red LED next to the relay shows that it is on. I tested both the conditions above and it works perfectly. The three other red LEDs at the bottom middle of the board indicate that it has proper +3.3V, +5V, and +12VDC supplies.

Next I have to make cables to connect between this board and the other 4 LCD keys and then wire up the switches and dials.

Quick update. The LCD keys are fully functional using a native control GUI, I will be working to implement a control program in my own code soon.



The camera has a hard time seeing the text in each switch, oh well.

Wiring up the switches and dials are next.

Nice to see I am not the only one with beer caps all over my work bench

Um. Your "breakout" board. Is that custom screened? Or an off the shelf product?

It's not every day I see a circuit board with "RDWHAHB" on it. That is so awesome I might wet myself.

It is a board that I custom designed, the RDWHAHB and flying bottle logo are my little signatures on it. There should be some details earlier in this thread. Glad you enjoy.

I will definitely make some videos once it is actually functional.

It has been a very busy month and not as much has been accomplished on this project as I would like. I am done wiring up the control panel for all of the functions needed to begin basic brewing.

My main focus for the last week or so has been code for the main microcontroller. So far I have routines to read all of the temperature sensors, turn on solenoid valves, and output PWM for the heating elements. Once I wrap a few more items into the code I will be brewing a few extract beers to replenish my stocks before the remaining items are coded and I can start AG.

No pictures for this updated but I will be sure to show some for the next.
