In my previous post I finished the hardware for the scale and calibrated it. This post covers getting data from the scale to Sparkfun’s Data Warehouse (Update: by 2021 the site has been taken down).

By the way, the nRF Master Control Panel (BLE) from Nordic is the perfect tool for debugging Bluetooth Low Energy devices and messages.  It understands a pile of standard Bluetooth data types as well as the Physical Web, so it’s a quick way to find out whether your Arduino project is sending the right data.
