In my previous post, I covered the mechanical construction of the scale. In this post, I finish assembling the scale, calibrating it, and installing it.
After painting I put feet on the scale so it won’t soak in water spilled on the floor.
…then bolted the Arduino 101, Load Cell, and Load Cell Amplifier to the bottom plate. Continue reading Dog Water Bowl Scale, Part 3: Final assembly and installation
In my previous post, I wrote the Raspberry Pi Node.js code to upload data from Pippa’s dog bed scale to data.sparkfun.com. This post covers how to make a Node.js program run automatically when the Pi is turned on. Oh, and at the end I installed the finished scale under Pippa’s bed.

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.
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.
