hi.. i want to ask about bluetooth..
is bluetooth shield can be used like bluetooth module?
Both practically identical, however some bluetooth modules have extra features that others do not. EX: signal strenght, HID interfacing with keyboards, mice, and headsets
can bluetooth shield communicate with phone to control a hardware (like magnetic switch)?
most phones with bluetooth can, like Iphones and Androids. Older phones, probably not.
hope anybody can help me..
Well I dont wanna, hmm... you didn't say please.
You dont need to send PMs.
Bluetooth is serial, so write a code that works over the USB cable (some examples are given with the Arduino software), and then take away the cable (must power the arduino with batteries or AC adapter) and replace it with the Bluetooth module/shield. The BT module(s) and your computer must be paired to work.
If you control the hardware like magnetic switch, I suggest you use the 315/433MHz ASK module. That's very suitable for that solution. Bluetooth is very suitable for huge data communication.
what i'm going to do is to control magnetic switch using phone bluetooth.. the switch is connect to bluetooth shield with arduino mega, so that it can controlled by phone bluetooth to disable or enable the switch to open the door...
is this possible??
