Smitty on Multiple 1 Wire Bus on Digital Pin ....

How best to achieve this ...

Not getting a successful compile from the below sketch ....

Very much a newb with ThingSpeak and Arduino ...

//Update the ThingSpeak Channel

float pinVoltage = sensors.(Temp1) ;
ThingSpeak.setField(1,pinVoltage);
pinVoltage = sensors.(Temp2)
ThingSpeak.setField(2,pinVoltage);

// Write the fields that you've set all at once.

Serial.print("Temperatures Uploaded to Cloud...

It is in this part here I am not sure how to Access my Temp1 and Temp2 values for ThingSpeak
