Sketch resumption after power loss

[TomGeorge]

Hi, @ian7511

@ian7511

Why does the sketch not resume when the battery reactivates the arduino? Is there any way I can make this happen without pressing the reset button

When the 5V is switched back on, is it a soft start or an immediate step up from 0V to 5V.
If a slow start, the reset circuitry may not respond and not be able to send a reset level to the controller.
