Bluetooth shield and accelerometer

Post by CAMS2908 » Wed Jan 14, 2015 12:30 am

Hi
I am currently working on a project for a Physics group looking at momentum and forces in a collision. What I would like to do is construct an arduino with an accelerometer and bluetooth shield that will link with smartphone that displays data on collision. Is this possible? if so what sketches would I need, I have scoured the internet but have come up with no results relating to what I would like to do..... suggestions?

Bluetooth has a limited range, so the first thing to consider will be the distance between the Arduino and sensors, and the device with which you want to display the data. In open air it can be up to 20 or so metres, but less if there is a wall or something in the way.

Starting backwards, you can use the free MIT App Inventor to create software to run on an Android device to display data sent from the Bluetooth shield:

If you're considering our accelerometer, there are links to how it works from the product page:

and the Bluetooth shield:

With regards to the sketch, there is never the perfect one for you to use, it's always best to write your own. Have a look at some Arduino tutorials on the Internet, or get a book for beginners such as:

to get moving on the programming and electronics front.
