ADXL377

No, just the top peak, with this value and the total mass of the object I can easily get the total force produced on the impact.

I`m doing some math and with 3.3 V my sensitivity is 7.15mV/G so I will put all this in a formula in order to get g results in the serial monitor, I have also set the baudrate higher and set the delay in 10.

Do you have any other sugestion?

I appreciate your help, thanks very much
