azure-sphere-iot-bubble-machine
An Internet Connected Bubble Machine. How awesome is that? This project was started for Hackathon 2020 (Microsoft's Employee Hackathon).
Bubble Machine Parts
- 3D Printable Parts : the current STL's are in the STL directory. You can also check Thingiverse but these might be slighly behind.
- DC Motor Controller : TB56612FNG
- Blower Fan: 5v 5015 Blower
- Wand Motor: TT Motor

Nota Bene
This project uses C++ but Microsoft DOES NOT support C++ as a development language for Azure Sphere. Azure Sphere is an example of embedded development and is fairly "bare metal". Even though we are using C++ the C++ library (i.e. STL) and much of the CRT (i.e. fopen) are not present in the tool-chain. Beware!
