Wireless EMG Sensor with Arduino IoT Cloud

[Jkolade936]

Hi there,

I'm using an MKR Wi-Fi 1010 board to collect data from a Myoware EMG sensor. I want all the data points collected and stored wirelessly, and I've been looking into Arduino IoT Cloud for this.

My current problem is with my current code, Arduino IoT Cloud only updates the dashboard with my data values every 4 seconds. This misses a lot of crucial data points that I would otherwise see in the Serial Plotter. It was suggested to me that I may be able to collect 5 seconds worth of data into a data packet of some sort (maybe an array) and send that all at once to the cloud.

Is Arduino IoT Cloud capable of receiving data in this way? If so, what modifications does my program need to make this happen?

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  CloudElectricPotential emgsignal;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.

  // Initialize serial and wait for port to open:
  Serial.begin(9600);
  // This delay gives the chance to wait for a Serial Monitor without blocking if none is found
  delay(1500); 

  // Defined in thingProperties.h
  initProperties();

  // Connect to Arduino IoT Cloud
  ArduinoCloud.begin(ArduinoIoTPreferredConnection);
