Messed up and messed around using millis(), need more time to debug and fix it (I’m not an expert when it comes to dealing with millis(), open to suggestions), I don’t want to use delay() since it interferes with my mAh measurement in the code.

Did a weird contraption of a capacitor, polarity protector diode on a perf board in order to act as a power distribution board since the boost converter had only 1 screw terminal..
