timing and decoupling

treebykooba:
So my question is...will the off timing be consistent? So I can just adjust the code accordingly? My loop probably takes about half a second longer now or so it seems. Or would it be less predictable? I assume it's because of the 47uf cap on the power rails...it's taking a bit of time to charge/decharge.

It's not supposed to charge/discharge under normal use.

If it is charging/discharging then it's either not in the right place for a decoupling capacitor or your power supply isn't supplying enough current for whatever it is you're building.
