set-up recomendation for arduino with 4x accelerometers

Projects General Guidance

Hello community :slight_smile:

Maybe this is a very general topic. My problem was I there are so many microcontroller and so many sensors - I was a bit overwhelmed and didn't want to risk buying something wrong.

So I want to to get data from 4 accelerometers and post-analyse them on a PC via python or something. So first want to get from 4 accelerometers at the same time the data and transfer it a PC to later on analyse it.

so I looked up accelerometer for arduino and got : ADXL335 Accelerometer

So these sensors need for each axis an analog input on the microcontroller. Arduino uno just got 6 inputs, just enough for 2 accelerometers right?

The mega got 16 inputs. Do i need the mega or is there a diffrent solution. And could there be any other troubles with using 4x accelerometers?

Thanks for any input! if you can recommend a good tutorial pls share :slight_smile:

that device needs 3 analog inputs per unit - one per axis

Yes, thats what i meant with:"So these sensors need for each axis an analog input on the microcontroller. Arduino uno just got 6 inputs, just enough for 2 accelerometers right?"

Did I understand something wrong?

I think we are agreeing here, are we?^^

So if a have an arduino uno with 6 analog inputs I can plug in 2 times x, y and z axis = 2 accelerometers.

I would like to have 4 accelerometers plugged in.

no clue whether it can process that much information and if they won't run into each other... but yes.

Your Yes is meant, that i need 4x 3 digital inputs on my MC?

Just wanna be sure.

Thanks wolframore

Maybe someone here that tried something similar and could tell me if there could be any problems with plugging 4 accelerometers on a arduino mega?
