Ok, i now first order parts that i can start to build something.
But i can't find the 74LV1G125. Not at farnell, not at digikey and in no German shop...
I think it's more future prove to use the 74LV1G125 cause i want to log the data to a SD card
have the network shield and also want to build some radio control for a water-pump (enocean if possible).
Does the wire from the heating system thermistors to the MCP3204 not affect the output of the thermistors (wire resistance)?
Or the 10K resistors? Not that the heating system turns into a air conditioning systems
Maybe its a big thing for an Arduino beginner. But like cabinetmakers say: "start with something
you like and something you have fun with. Don't select your project by easy or difficult".
I think it's learning by doing. And if the help here is so great like yours, than we can build a machine
to take over the world *lol
