Problem with Cloud Dimmed Light

Development Tools Cloud IoT
1

Hi,
with this sketch:

#include "arduino_secrets.h"
/* 
  Sketch generated by the Arduino IoT Cloud Thing "Untitled"
  https://create.arduino.cc/cloud/things/5e625f25-4d71-473d-ac9a-e33135c80ef8 

  Arduino IoT Cloud Variables description

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

  CloudDimmedLight white;

  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.
*/

#include "thingProperties.h"

void setup() {
  // 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);
  
  setDebugMessageLevel(2);
  ArduinoCloud.printDebugInfo();
}

void loop() {
  ArduinoCloud.update();
  
}


/*
  Since White is READ_WRITE variable, onWhiteChange() is
  executed every time a new value is received from IoT Cloud.
*/
void onWhiteChange()  {
  int brightness = map(dimmedLightwhite.getBrightness(),0,100,0,255);
  if(dimmedLightwhite.getSwitch()){
    analogWrite(5, brightness);
  }
  else{
    analogWrite(5, LOW);
  }
}

gives me this error:

I cannot understand where I am going wrong and I need help.

Hi @eziogi. If looks like the name of your Cloud variable is white, not dimmedLightwhite:

If so, just correct the variable name in the references in the sketch:

@@ -43,8 +43,8 @@ void loop() {
   executed every time a new value is received from IoT Cloud.

 void onWhiteChange()  {
-  int brightness = map(dimmedLightwhite.getBrightness(),0,100,0,255);

+  if(white.getSwitch()){
     analogWrite(5, brightness);
   }
   else{

Hi,
next weekend I make the changes.
Thanks

I made the changes as you advised and now it works regularly.

Thank you
