hello i am an 2nd year electronic student and for my telecom lectural i want to make a shield that help sending programm to my arduino uno using bluetooth and i do no really know where to start.
i have seen this schematic
// arduino bluetooth //that i want to make (since i must make the shield myself) but i intent to buy this bluetooth module(cause there is no way that i can weld the chip use there myself)
// //
can someone please help me i kind of lost please =( =( =(
I don't think you know what you want but, whatever it is, you can safely forget about the schematic. The module you refer to is a common HC-0x module on a back board. This may be connected to your Arduino simply by using four male/female jumpers. If you really need to make a shield you could get a small prototyping shield kit and fix the same module to that. Only four connections are needed. Other than for the intellectual exercise, I don't know why you would bother, unless you can think of other uses for the proto shield, and then it's not uncommon to use flying leads for the Bluetooth anyway.
