Switching power sources, battery charging

[Archangel]

One issue that is plaguing me is current requirement. The garage needs at least 16 zones (2 stories); that quickly adds up using average 20mA LEDs to show status. I also want to have visibility of the other buildings from any keyboard, even more current required.

I have several older units of this graphic LCD, mine are 90-100mA:

Much lower current required than LEDs and much more flexible.

Hi Robert,
Do you mean you cannot waste the power or do you mean you need to limit the output draw on the PIC?
