    hi, i'm trying to cobble together a few different circiuts to run off the same source for simplicity sake. i dont really care if its battery or plug. i was wondering if there is a simple way to do this that can be applied in many different circumstances.

    currently i have 3 seperate circuits, 2 run off 9volt batteries and the other runs off of 2 in a dual rail setup thingy. but i'd like to understand it in a way that i can apply it to other things as well.

    thanks for your help.

    You can power as many circuits as you want from one battery if it is big enough to last long enough.

    A dual plolarity rail is different. Maybe the circuit can be re-designed to use a single polarity supply.

    When I built my robots, I used one 12 volt source, then for the individual voltages for each circuit systems I made quick voltage regulators,

    EX. 5V. for infra red det.another 5V. to run drive motors, 8 volt. for electronics. ect...
