I've created a project with arduino UNO + ethernetshield.
I've added a graph widget to make a temperature graph. But its not showing any graph,
Though my device is connected. Here is my code:
From Loop function:
// This function is called when the Cayenne widget requests data for the Virtual Pin.
int sensorReading = analogRead(tmpPin);
float temperature = sensorReading / 9.31;
Its not entering into CAYENNE_OUT(VIRTUAL_PIN) function.
Pls help me.
