This project will guide you through creating simple circuits for the sensors, hacking the motor shield so it can be stacked with the arduino and ethernet shield and implementation of the code (note all code is provided and is fully commented). The project is laid out in the following manner. First the controller and system will be constructed. Then the logic behind the code will be explained. The last page will contain the code and link to download so it can be installed on the arduino.
So I hope you enjoy this instructable, gain from it and most importantly have fun.

Step 1: Requirements and parts
1. Arduino ($30)
2. Ethernet shield ($50)
3. Motor Shield ($20)
4. Analog temperature (TMP36) sensor ($2)
5. Photocell ($1)
6. 20 pin 0.1" Female Headers ($3)
7. Breadboarding Wire Bundle (6)
8. Breadboard friendly 2.1mm DC Jack ($1)
9. 12 V Stepper Motor (14)
10. 100 ohm resistor
11. MicroSD card (1gb card is good and can be found for as little as $2).
12. 2 Full breadboards ($14)
13. 12V AC adapter. (powers the motor only)
14. battery pack for the arduino
Remember, all these parts can be used for other projects, so don't worry too much about the cost because you'll be able to use them in many more projects, unless of course you are gonna use this as a permanent installment.
3. Small screwdriver.
