Sticking two ADXL345 accelerometer on a stick

[juliettex]

Hello everyone! I am very new to arduino and electronics as a whole. I am working on my first arduino project at the moment and my goal is to have a physical stick/bar with two ADXL345 accelerometer on each tip of the stick. (so one on each side). The accelerometer will then detect the angle of the stick. I was wondering what was the best way to install my sensors on the stick. I was thinking about hot glue, but I don't know if it is the best alternative. I have a metal bar right now, but maybe a wooden stick would be better ?

Thank you so much for your guidance !

The accelerometer will then detect the angle of the stick.

Not sure I see how.

You coul use double sided tape? As long as nothing is being short circuited there's no reason not to use metal.

[juliettex]

okay! Great! I also have little breadboards that I can glue on the stick and I can put the accelerometer on the breadboards? Maybe that could work like the double sided tape?

[madmark2150]

Double stick tape & breadboards will be fragile. It will work, once or twice. What is this to be used for? More than a test?
also, that module is three axis, why do you need two?

[juliettex]

I wanted one on each side to detect if I do a fast movement toward the right, for example, to be able to catch the acceleration of the movement. I want to be able to know if I swing towards the right or left with the stick. My initial post was lacking information, I apologize.

As for the breadboard this is what I have. I want to put some hot glue under it so it sticks better, but indeed, it is a little bit fragile right now.

One unit will detect motion in both directions on all three axes. Impulse shock is the enemy of your mounting.

I agree, with @madmark2150 , if the stick cannot bend then you only need one sensor.

With a unit at each end, both will read the same.
