Simple Electronic Help
I'm currently building a small hybrid solar panel car for a school sompetition(runs off of batteries or solar), and I need a bit of wiring help, here's my problem and some other stuff. I have 2 SPDT switches and 1 DPDT switch. I'm using one of the spdt switch for on and off, the other to switch from solar to battery, but i need help for the dpdt. There's 2 sets of solar panels (2 pairs of 3 hooked in series, for simplicity sake, I'm just going to say 2 solar panels), and I want to hook them up to the dpdt switch and the motor and the battery so that: I can turn on/off the motor (easy), switch between solar and battery (easy), and switch between paralell solarpanels or series (what I'm having problems with), any help?
