I thought about creating an IMU american football. I have a Nerf foam football which will perfectly do for my project, but i'm still wondering what would be the best way to tackle this project. Here's exactly what I'm trying to achieve:
-Measure RPM of each throw and display it to the user.
-Measure throwing speeds -Measure distance of a throw
I have an accelerometer and a magnetometer at home which I could use.
What would be the easiest possible way to achieve my primary goal, and possibly even my secondary goals? Do i need both the accelerometer and magnetometer, or should i get a gyro?
Do you think the arduino "millis()" will do for measuring time? The ball will have to work up to 600RPM on each throw. I prefer not to make use of a wifi or bluetooth module just yet.
Thank you for your help!
