This is a weekend project that I spend time on once in a while to hack and improve. 
The idea was to make this simple vacuum cleaner brainy and more importantly, remote monitor-able and controllable.
Here’s a summary of its capabilities up till this point in time:
- Battery and charging voltage monitoring
- Mode (charging, idle, vacuuming, etc) monitoring
- Remote control via IR led (thanks to AnalysIR library)

Happy 
-ing!
