Well, I think I have finally done it. First and foremost, thank you, thank you, thank you from the bottom of my heart for a) FuzzeWuzze's DIY, and b) everybody's help. I literally could not have started or finished this otherwise. I went barebones except for the following additions: 1. Power...

Thank you, I suspected as much and, honestly, I just want to put this project to bed. I have LED indicators for the 2x Relay, on/off switch for the Arduino, and a suspend button for the RPi. I think that is enough customization for this project. I know it will be worth it but this has been...

[Original Question Redacted] [New Question] Has anyone setup the BrewPi to use an LCD (20x4)? I've seen the mega thread that utilized the LCD connected to the Arduino Uno however, for practical reasons, I'd prefer to run it off of the RaspberryPi. Connecting it seems easy enough based on the...

These are the ones I just bought. https://www.amazon.com/gp/product/B01JKVRVNI/?tag=skimlinks_replacement-20 I had bought these: https://www.amazon.com/gp/product/B00KUNKR3M/?tag=skimlinks_replacement-20 (none of the wires were yellow though)

Any way to test the sensors other than trial and error? They aren't terribly expensive but if I'm buying bag after bag of sensors the whole build gets silly

I understand that but unless the color of the wires differs from one sensor to the next - from the same manufacturer, packaged together - they are wired correctly. I've decided to order new sensors and the required parts to utilize mini-xlr connectors in hopes of making my job easier when in...

So with everything working, I foolishly tried to put the fridge "back together" (i.e. place the wires in their final position, move the parts from outside the case to inside the case, general clean-up - POWER OFF THE WHOLE TIME) and, wouldn't you know it, the sensors stopped working! So I...

Wanted to thank everyone for their help. Its been almost four days without issue. I believe the big thing - in my case - was proper grounding. I found it is important to keep the sensor and arduino ground separate and not earth ground. Happy brewing!

I ordered and am receiving today the following wall-wort (see what I did there? haha): https://www.amazon.com/gp/product/B018OLREG4/?tag=skimlinks_replacement-20 ... with no obvious ground, how would I safely ground that circuit (is that the proper terminology)?

As of Sunday, the sensors, relay and arduino haven't been grounded to earth, just metal (is that a problem?). The cooling unit and heater are grounded to earth. Well see, thats the problem; I only know how to follow instructions, I don't know what I am doing haha (though the fridge is never...

I noticed that too. I've tried multiple grounding schemes. I'm currently on ~12 hours no issues. The only change I made was I've place the eurostyle connector and arduino on a rubber mat. I'm think that if I rig a Faraday box and place both in there, I won't have issues any longer (seriously).

Nothing lasts forever. After about seven hours without the dreaded disconnect from pin 18, that's exactly what happened again . Any thoughts on what I should check next? New sensors? Would the fact that the fridge sits on carpet be an issue? Maybe the Arduino is defective? Ugg :(

Yes, sir. Right now, I am investigating the possibility that my grounding scheme is messing up the sensors. Based on this link: https://community.brewpi.com/t/troubleshooting-temperature-sensors/14/16 I have grounded the sensors to the fridge metal itself and grounded the condenser and heater...

What in the holy hell (albeit ridiculously impressive) is that? Haha Here is what I used: USB goes to RPi Instead of the outlet, I wired the compressor and heater directly into the grounded chord via the 2x Relay Board.

5v off the Arduino. What is a pull-up resistor? Was it included in the schematics that's FuzzeWuzze drew up?
