How to make an Arduino Battery Charger v2

So we are back with an update to the NiMh battery charger. In this iteration, we are able to charge a single NiMh AA battery(more batteries would only require a different battery holder) in constant current mode. Charging is stopped when when the INA219 current sensor module detects a drop in the current (negative delta V).

Once We have this running reliably, the next step is to take what we learned here and apply it to a LiPo battery.

All of my sketches are available here:
