I’m using Arduino for some months and have a lot of fun, I’m learning electronics this way.
I already control some stuff in our farm based (some time) on temperature. I’m using Dallas DS18B20.
Now, I’m looking to control heating light based on temperature to install in many place (about 10). I’m looking for the cheapest way to connect a DS18B20 instead of a full Atmega168/368 Arduino, I’m looking for another Atmel if possible, a smaller one compatible with Arduino IDE.
