Filtering out high frequency from my input graph

This can be done in software. The modulated signal can trigger an interrupt where you (re-)start a one shot timer. Set the timeout period to 70 µs. The timeout will happen only if the 16 kHz pulses do ...

Resistive current sensor shows reading when I connect it in series with a battery while no current is flowing through it

The shunt used only generates 375uV. This is not ultra low, but precautions are required. Common Mode Rejection Ratio: The INA219 has a typical CMRR of 120dB. Hence by moving the sense point to the ...

You wrote: " I did the same with a multimeter and a reading of 0.0003 mV was obtained across the shunt, which is also negligible." Can you really measure 300nV ? An ordinary multimeter can ...
