Having some problems with basic C++ / Arduino typecasting… I think. I’m playing with the Nightshade energyShield and trying to Spark.publish() a sprintf’d JSON string but the numbers are getting messed up, and I can’t figure out whether it’s the Wire() not working or if it is a sprintf typecasting …

Serial.print() vs sprintf() and typecasting

Looking like it might be Shield Shield and the TI Logic Level converter used to raise the voltage to 5V.
