Hi guys! I am korean student. Now, i'm making custom phone case for my graduate paper. And, i want to test my case's safety by arduino. So i want to measure impulse by arduino. my expriment is drop the phone with phone case and measure impulse. can you help me how to finish this expriment?

You're using the word impulse, but I think we've lost something in translation.  What does that word mean to you?

If you want to see how hard the phone hit the ground, then use the accelerometer in the phone.

Please do not PM with technical questions or comments.  Keep Arduino stuff out on the boards where it belongs.

Impulse = integral of force with respect to  time.

Typically people use a fast, high-g accelerometer to measure it, e.g. ADXL375, or maybe even the one in the phone.
