It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in ...

The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

Duh, the Arduino is just an AVR with a bunch of premade libraries. So everything you can do on the Arduino you can do on an AVR, the AVR can do it faster, but requires more time on the coding.
