How do I wire a 5v regulator?
I am just hooking up a wireless weather station and it uses 4 AA batteries to power it. (it's a 3v supply to the unit) I want to use a solar panel I have to power it. It's a very small solar panel with a 15-16v output and really low current so that is not an issue. Anyways, I want to use a 5v regulator to charge rechargeable batteries in the transmitter, but I've seen capacitors used in the wiring and what is that about? Also, it's 3 pins, and the middle is ground, but how do you wire it and do you even need it? Thanks
