Hi, I am looking to produce a circuit that records vibration, stores the data then transfer it via bluetooth to a laptop/ tablet. Is there an Arduino board that would allow this to be feasible? Thanks
All of them.
I don't think there is a pre-built one with a vibration sensor plus bluetooth but I would not be surprised if you found one. Usually you would add sensors and interfaces to a basic Arduino.
Sorry, I am looking at using an accelerometer attached to the Arduino Board. The requirements for the board was that it was to have a storage for data received from the accelerometer and Bluetooth capability to transfer to laptop/tablet. Thanks
"Storage for data received" is pretty loose and, while there is a great swag of different Arduinos, yours is a pretty tall order. However, there is an Arduino with built-in bluetooth, I think it is the BLEduino, and it may have enough memory to store your data, whatever that might be. It is not hard to add an SD card to any board, or bluetooth for that matter. You just need to have a better idea of what you want, and be more open minded. There is also an Arduino with on-board accellerometers, the 101.
The BBC micro:bit has an ARM CPU with BLE (nrf51) and an accelerator among other devices such as 25 red LEDs! But I have no idea how much storage you need. The board can be programmed in C/C++ using the Arduino IDE.
i am looking at proving a concept would work by using Bluetooth to transfer data received from an accelerometer that is sensing vibration of a drive shaft/gearbox etc. instead of using a PCMCIA Card i was intending to transfer information via Bluetooth The "storage for data" is relating to data received from the accelerometer over a period of time (duration is not critical as it is only a concept i intend proving works)
A normal Arduino (ie Uno) does not have much storage, and does not have bluetooth. Yes, you can add that, but it gets a bit unwieldy. You might consider one of the Adafruit "Bluefruit Feather" board, which are compatible with the Arduino IDE, and also include a BTLE comm module.

(Be careful about "Bluetooth" vs "Bluetooth LE", though. They're substantially different (and in particular, not all laptops with "bluetooth" include BTLE support.))
Thank you for taking the time to give your input. I havent considered the adafruit but will look into this option. If I can somehow attach an accelerometer input then all's good in the world. Thanks again best regards

More loose talk.............
Thanks for your pointless input! Its not "Loose talk" as you so helpfully state. The requirement for the concept is that it works and not stores the data a two hour sortie a Wildcat aircraft would take.
Good. "2hrs" is a specific number.
Even to prove the concept, you must have a specific amount of data you need. An Uno has a really tiny memory. Like you can't even store a 10th of a second of data at 5kHz sample rate. (And 5kHz is pretty slow for many vibration studies.)
