Getting accelerometer values Nano 33 IOT to cloud 16g

Other Hardware Sensors
1

Hi everyone,

I've been trying to get accelerometer values from a nano 33 iot to the cloud at 16g of acceleration but impossible to get the right calibration or get the values sent to the cloud and plotted there...

Any help would be very much appreciated (even finding the right code I'm really new at this)

Hi @antoinehigham.

I would guess this problem is completely separate from the Arduino Cloud aspect of the project.

My recommendation is for you to create a very simple sketch that only reads the accelerometer and prints the results to Serial Monitor. If you aren't able to have a USB connection while the readings are being taken, you can store them in an array which is then printed to Serial once the board is connected to the computer.

I also recommend starting by creating a simple Arduino Cloud IoT project that only sets a Variable to random numbers and plots those random numbers.

For example, if you created a Thing with an "Integer Number" type variable named reading, you can simply add this line of code to the loop function in the basic Thing sketch that will be automatically generated for you:

reading = random(100);

Then upload that Thing sketch to your Nano 33 IoT board.

After that, create a dashboard and add a "Chart" widget associated with the reading Variable. You should now see random numbers between 0 and 99 plotted in the widget.

You can use this guide and the other associated documentation as a reference to understand how to use Arduino Cloud's IoT features:

https://docs.arduino.cc/arduino-cloud/guides/overview/

Once you have a 100% perfectly working simple sketch that reads the accelerometer, and another 100% perfectly working simple IoT project that plots random numbers, the next step will be to merge the accelerometer reading code into your Thing sketch and then you will have accomplished your goal!

Hi thank you so much,

Managed to get the simple accelerometer working on the serial port (no problem there).
Same thing for getting the wifi signal separetely (signal strength received by the Arduino is good).

Unfortunately, trying to get the accelerometer readings directly sent to the cloud doesn't work (the device is noww always "offline")

If you have any tips on that side of things...
Thanks again for the quick answer
