Hi guys and girls. I am wondering about using bluetooth with my arduino and maybe another but not a mobile phone or tablet.
I want to make a system that monitors position and movement of a boat on a trailer and feeds the info back to a tractor driver. If the sensors detect the boats mast is up and the boat is moving can bluetooth send the sensors info to a receiving unit that would then alert the driver?
Basically I cannot have a wired connection between the two units, it must be remote but the distance between transmitter and receiver would be only a couple of metres.
There are some pretty spectacularly inexpensive serial Bluetooth modules out the (HC-05/HC-06 for instance) that basically function exactly as a serial port, no extra interface or programming required. You simply send and receive serial (just like you would do to send data to the serial monitor) and they just relay the data. One could be set as master, the other as slave with auto detect/auto connect, all which you set up by connecting a serial cable to the module and sending "AT" commands from serial monitor (or the serial communciation program of your preference), and you have pretty effortless Bluetooth serial communication. Since you are not needing to send a ton of data you could use a low baud setting (like 9600) and have a fairly error free data link.
Also these modules are easy enough to set up it is kind of fun just to play with them, you can send/receive data from you phone/tablet/laptop, whatever you have that has Bluetooth. It is kind of a kick getting your Arduino to take orders from your phone!
The joys of SOPs. The crew have to remain seated until the boat has been pulled up the slipway and come to a stop.
The mast is the last thng to be lowered before the rehousing is done with all crew disembarked. The mast confines room to move on the deck and has antenna which are at eye level and could easily catch you out.
Yes a check sheet would be too easy but doesn't account for complacancy.
