An Arduino library for the INA219 current and power sensor module.
It allows to set various ADC modes, gains and bus voltage ranges. Continous mode, triggered mode, power down and ADC off mode are supported.
I attached a list of public functions and a fritzing scheme for the example sketches.

Note: Version 1.1.2 corrected a misspelling of "continuous" which might lead to backwards incompatibilities. You might need to change your code.
