Looks good!
Thanks for the info, Ill look into those and decide. I saw the one you posted on amazon and it was almost $30 so I turned away from it, but thats a lot cheaper on ebay, Ill have to consider. Though I am liking the idea of the laptop charger because it already controls and regulates the output and has the easy usb interface which plugs very nicely into the Mega ADK which im using.
Got a nice little shipment of some parts to start piecing some stuff together so going to start the build part of the thread
I found this Android-to-Arduino BT shield...looks promising.

Also not sure how many pins the things like temp probes and switches will take up
Heres the inputs I see having:
2 - temp probes
2 - basic on/off switches for pump
2 - ARM/DISARM switches for elements (idea will be when using them manually to flip these switches to arm the elements then use the LCD display/buttons to set temp and the PID library will control the output to turn elements on and off)
4 - buttons to control the LCD screen and set temps (Mode, Up, Down, Set)
1 - USB interface (this is already taken care of by the Arduino Mega ADK, this can interface with android devices through USB, which is perfect)
10 - total not counting the USB
Here are the outputs I see having:
2 - SSRs for the pump on/off control - assuming will need 2 pins
2 - SSRs for the element on/off that will be controlled by the PID library - 2 pins
1 - the USB interface can both send and receive so that will talk to the android
1 - LCD display to display whats happening and select temps for elements to hold - needs 11 pins
4 - Lights to show when pumps/elements are on
1 - Buzzer/Alarm for signalling temp has been reached
10 - total not counting the USB
Yeah that initial post i was just getting started with arduino, Ive since learned a lot and have everything wired
break;
So In 10 days I get back from deployment and I just got an email from Stout Tanks saying my tanks are done. So I should be able to start the rest of the build soon
