Hi, i am quite new to the arduino and micro controller world, i have picked myself an project which is driving
me through the roof, and that is the Math around this.
The basics are an impact detection system using three 4 sound sensors and an Arduino Uno.
My problem and honestly i might be over complicating this is as follow.
while drawing a possible scenario i realized that there is a few things i did not take into consideration while doing my programming..
The problem i see, once i get an input on my first sensor (right Bottom ) Sensor 0,
that sets the base for the rest of the calculations to happen.
but at the moment the sensor is triggered there is already a set distance covered, meaning that the distance i calculate for sensor 1,2,3 will not be from the impact area, but rather from
A-1 B-2 and C-3 which leaves a big hole in my calculations.... smiley-cry
i have been looking at crating triangles from example 3-1-A to determine the XY Coordinate for A, the same for B and C....
Then using Equation of a Circle from 3 Points to determine the center point of the circle..
My problem is angels, i do not have any incoming angels to determine the XY of ABC...
Could anyone offer me a fresh approach to this, either better mathematical approach, or a different way i should be looking at this problem..
Thank you for your time...
