How are you today hope all is well with you.I am going to work on a project with the following structure Arduino uno +Ethernet shieled+ Sensor shield in the following link http://arduino-info.wikispaces.com/SensorShield
so Please I would like to ask Many questions 1)will it work without problems if i put the Ethernet shield over the uno and put the sensors Shield over the Ethernet shield or i will face troubles.
2)I will use three sensors each sensor works on 5v can the uno provide this volt to them through the sensor shield or i will need a power source for the three sensors .
3)I will Make this system interact with another system that composed from Arduino uno + GSM GPRS Shield(with it's GSM\GPRS Module in the following link http://store.open-electronics.org/GSM_GPRS_GPS_SHIELD) through software serial Is it possible or i will face problems.
If any one have any advice for me I will be grateful.Many Thanks In advance
