Hi all..

I am using the ADXL345 for vibration trending.Accelerometer ADXL345
I am using the Arduino Uno R3 as a microcontroller. Arduino Uno Board R3

I want to check, is it possible to have 3 ADXL345 Accelerometer on a Arduino Uno via I2C connections?
I understand that the ADXL345 comes with a specific I2C address by default. Is it possible to check the default address and reassign it ?

Many thanks!

The module has a 'chip select' pin.
Datasheet also states that two different addresses can be selected with the SDO pin.

Hi,

Do u mind breaking it down to a more layman method?

Since each board has a CS pin you can select the chip you want to talk to by bringing the pin LOW.
You use 3 Arduino digital pins for the chip selects.
