Fwiw the nano is a what you want if your looking for a small board. probably even cheaper than the micro too. u don't see a whole lot of people use the micro because it's so different than all the other boards. The nano is pin for pin compatible with the uno
It will update on pours. I don't know how long your cat5 run is, that could be the problem. my flow meter wires are only about 15" long and my arduino is in the fridge with everything else communicating over Bluetooth to the pi.
2 Things I never got to work right modifying any of the analog pins in the code and using a pro micro. the nanos and minis work just fine but something about the micro, wouldn't work for me 3 years ago so I don't really have a lot of notes on the subject only that I can tell you, use...
What's the max peak amp of your fridge, cause compressor and fan motors spike up quite a bit higher than their running amperage when they initially kick on
Use a full size coupling to get the dimple size right. then you can come back with the half coupling to get the seat just right. as far as coupling size verses pull through tool. you can take a hammer and lightly pound the dimple back in to reduce the size for a snug fit.
The solid red light means that you have 4.6-5.1V coming in. there is no way for the pi to determine if the power supply can handle the necessary amperage needed to connect to wifi or control USB equipment. amperage can only be drawn through the power supply it's not a supplied thing. if the...
Getting power doesn't mean you have sufficient power... I just bought a pi zerow from canakit with the full kit. it comes with a 1a power supply. which is plenty of power for a zero. guess what happened when I plugged in my 3d printer while the wifi was active . So now it's on a 2.5a psu...
