The valve solenoid and flow meters are pretty much completely seperate cicuitry, even tho I'm using the same 6-pin connector per solenoid/flow counter stack. The solenoid relays have noting to do with the flow counters. 3 of the pins on each connector are for flow counters, the 3 remaining pins for the solenoid.Hello CaptnDelta
Thank you very much for all of this. I have a few questions.
1. On the relay board does your 5 shut off valves only hook up to them? AND NOT YOUR FLOW METERS
I used those here: http://www.ebay.com/itm/1-2-12-Volt...tic-Body-Water-etc-DDT-CS-12VDC-/1214370630032. What is your brand of Shut off valves that you are using? What reasonably priced solenoids with a larger orifice would you use?
They are ok for me, but I got a long beer line which helps with foaming. Some beers like Pilsener don't do too well, tho. I haven't found anything yet which I'd consider a better replacement, maybe someone here can find something better. I'd recommend to get just one, hook it up to your tap, and just drive it straight with 12V DC. See how your beer pours before committing to them. I also removed the inlet screens on the valves, that helped quite a bit.
Yes, I think this should work3. What about this to go from breadboard to rpi? I am using the rpi 2 with the 40 pin GPIO. If this works then I would call this M13 and would tie everything to this?

Yes, thats correct, I just soldered in pins, and then used this cable:4. What is the 9 pin ribbon cable that you used to go from relay to breadboard? (part number) Did you cut a 40 pin ribbon down to 9 pin? Did you use breadboard pins soldered to the breadboard and then underneath (which we cannot see from the pictures) jumper to the underneath post on ULN1?

JP1 just supplies power to the relay board circuitry, to power the relays. I just used leftovers from the JP2 cable above, same type pins soldered into the breadboard. This is not hooked to the alamode below.5. What cable did you use for JPI? Is JP1 the three little squares on the alamode next to the SD car slot labled U3? Did you hook it up the same way as number 4 underneath the board?
I used these: http://www.amazon.com/gp/product/B00H8A8BQ0/?tag=skimlinks_replacement-206. What is a part number of X1 screw down ports? Do those solder directly to the breadboard?
and yes, they're soldered onto the bread board.
Correct. In your case (with the Uno) that would be a bit different, you probably wouldn't have that on your board.7. JP3 looks like it is ports D0 - D7 on the alamode I believe. Am I correct?
Yes, it gets me the 5V from the alamode to power the flow meters. In your case (with the Uno) that would be a bit different, you probably wouldn't have that on your board.8. Jp4 is the POWER port on the alamode????
9. From the third picture of your box. What is the white transformer?
10. Can you explain the green, white, and black power that you are using from the wall wart that plugs into the project box? Does your white go to port 1 on X5? What is port 2, and 3 on X5 (12V)
The white box is a step down converter to create 5V form the 12V power supply that I'm using: http://www.amazon.com/gp/product/B00A71CMDU/?tag=skimlinks_replacement-20
Basically, I have a 12V/10A power supply that plugs into the connector on the project box, the 5 V required for RPi, Alamode and Relay board are from there created via the step down converter.
The different "ports" on X1, X4 and X5 are just there to make it easier to hook all those wires up. For X5, I just use one "port" to bring the 12V power in, then use the "port" next to it to power the relay outputs. It's just there to make wiring easier (basically instead of using wire nuts, etc).
Cheers,
