I just ordered a bunch of proto type board, smaller pieces PM me if you want some. We will need this(or at least make it easier) for the base to put the relays on.

I'd love some, since I am on a very tight schedule this week, I will be going pre-fab with an 8 channel relay board for the tutorial as well as throwing in a little freebie tutorial on my pico build later tonight

Sure thing I'll hit you up when they come in

Is this the right rtc?

Waterproof temp probe

And temp probe

Both temp probes are correct, the rtc is not

Will this one work?

Thanks.

Will this work for the relay board?

I get my Due on Monday so I'll be starting to play around with it then. Hopefully I can get some additional components ordered as well.

Got me a Uno.. I'll be jumping on the band wagon after I get my BML LEDs. Looking to use it to dim lights and what not. Maybe I'll see about setting it up to control my chiller and calcium reactor and some monitoring.. This will be a fun project.

I'm getting an error when I try and upload the one_wire_sketch. Here is the error.

In file included from one_wire_address_finder.pde:7:
/Users/mac_mini_office/Documents/Arduino/libraries/OneWire/OneWire.h:77: error: #error "Please define I/O register types here"
/Users/mac_mini_office/Documents/Arduino/libraries/OneWire/OneWire.h:84: error: 'IO_REG_TYPE' does not name a type
/Users/mac_mini_office/Documents/Arduino/libraries/OneWire/OneWire.h:85: error: ISO C++ forbids declaration of 'IO_REG_TYPE' with no type
/Users/mac_mini_office/Documents/Arduino/libraries/OneWire/OneWire.h:85: error: expected ';' before '*' token
Any ideas?
