Now when you use the wire library, you call the twowirewrite function which copies your data into a 2nd. The arduino wire library rheingold heavyrheingold heavy. If youre using one of these libraries, you need to install it first. This tutorial will show you how to connect many ds18b20, 1wire temperature sensors to your arduino board, using only 1 digital io pin one cable. So its a bit of a catch 22 with using this library to talk to wire.

To enable the library, youll need to include it, and you also need to include the spi and wire libraries. Arduino install\hardware\arduino\avr\libraries\wire. I asked the exact same question recently, and it turns out wire. The temperature control library allows us to get the temperature and the onewire allows us to wire the temperature sensor using only one wire if you look at the schematic youll see the temperature sensor is wired with.
