Currently, I'm designing a solar battery charger which can charge a battery using a LM317T as a current regulator.
But my problem is I need a "automatic switch" that can allow me to switch between two curcuit:
one is for charging the battery, the other one is for discharging through load (eg some LEDs).
I am still a beginner.
Can some experts give me some advice on this design?
The battery im using is two 1.2 V Ni-Cad, im assuming they will give me 3 V after fully charged, is it correct?
And how to design that "switch"?
