I am a newbie with arduino and I would like your help to develop my programming
I want to water my lawn every night at 09:00PM, but in case if during the day has rained or it is raining at night, my moisture sensor will give signal to Arduino to not switch on my solenoid valves to water my lawn.
One more thing is, I want to use ethernet shield to control manually my system, as an additional feature of this programming where using a cell phone I can switch on/off the irrigation system.
I have available to this project:
01 Arduino Mega
01 Ethernet Shield
02 Soil Moisture Sensors
01 Relay Shield (8 relays)
The moisture sensor is one like thishttp://seeedstudio.com/wiki/Grove_-_Moisture_Sensor
Ps.: I bought Arduino Mega and 8 relays shield and Ethernet shield because I want to automate a lot of things in my house (Lamps, garage door, etc.)
Thank you for your help guys.
