it involves air pressure switches for a compressor and 4x individual airbags.
at the moment each bag can be inflated and DE-flated with a rocker type switch using digital valves.
What i wanted to know is if i can replace this with the following scenario;
1x Arduino Board
1x WiFi shield or Bluetooth Board (not sure which is best yet... i am thinking Bluetooth)
1x iPhone & app to communicate via Bluetooth to raise/lower the air pressure and perhaps monitor pressure in each bag, and have 3 preset buttons to set the pressure accordingly.
whats my best approach to this? and i guess i will need some sort of digital pressure sender unit to read the pressure and send the data to the board which is then displayed on the iPhone.
i am not even sure the iPhone is best / easiest way yet, i can do it with an LCD screen but i like the idea of Bluetooth iPhone connectivity.
Many people like the idea of Bluetooth iPhone connectivity, unfortunately Apple doesn't expose the Bluetooth serial protocol in their API, which is why you don't see anything that uses Bluetooth for data transfer on an iPhone.
Is this project going to be mobile? You'll need to make sure that the wifi shield you choose supports ad-hoc networking. Most only connect to an existing wi-fi network.
