I need a bit of help figuring if my project is feasible in arduino, and if yes; the better ways to proceed.
I am trying to build a wireless system, with sensors sending data to a range of displays (only 1 for now) or computer(s) (eg, pc + phone).
The sensors I am thinking about are a 6-DOF and a GPS, display is a LCD (parallel); I currently have this working fine all linked to an Arduino (6-Dof using newsoftserial), Gps on serial, Lcd (an Hitachi but thinking about some 7-digit through a max7219), also logging data to an Sd card.
My next step would be to have the LCD split from the Arduino, so the sensor box can be fixed somewhere down below (on the boat), and the LCD with me outside. (GPS will be fine down below).
From what I understand (reading through the forums and the net), the LCD not being serial, I'll need an arduino for sure on the LCD side, am I right?
On the sensor side it looks a bit more complicated; both gps and 6-DOF are currently linked to an arduino, but each send data serially. So I could get two wireless modem (right word?), hook them to each of the sensor.
Questions: 1) Hooking up a GPS to a wireless makes sense? fast enough for the data? (GPRMC nmea data at 5hz?) 2) On the sensor side, it could be between 2 modems + 0 arduino and 1 modem + 1 arduino.
Along with the LCD display, I would also like to access the wireless data over a computer (pc or android)
Questions (cont.): 3) The big one; what kind of wireless protocol is best for what I am trying to do? (Xbee, Wifi, Bluetooth, Radio), I am getting a bit confused on what's available.
