I have a project that I'd like to power with a 12 battery and a 12 Volt DC adapter. I would like the circuit to be powered by the "battery" when the DC adapter in not plugged into the "project. I'm using a DC Jack to connect the DC adapter to the project. The DC adapter is 12 Volts and 1 Amp, The battery is an a A23 also 12 Volts.
I would need the circuit to primarily operate on the DC adapter. and switch to the battery when the DC power "jack" is removed. I don't want to use an external switch to cycle between power sources. I want that function to be automatic.
Could one of you guys that know how to do this post up a schematic for me, I'd really appreciate that.
I imagine this is Electronics engineering 101 to most of you guys, but I don't engineer electronics.
Thanks.
