coordonate

Hi :wink:
i'm looking for a way to calculate the coordinate of the impact of the bullet on a target!
ideas?

yes, you need multiple impact sensors (at least 3) and reverse calculate the timing of the triggers to the impact. Non trivial hyperbola math.

please read this thread from 2011 - Impact location, using four sound sensors. - Sensors - Arduino Forum - it discusses the math and an alternative solution. If there are questions thereafter, post them as explicit as you can.
