Hello, and I am new to circuitry and stuff but I am connecting 2 micro-controller boards together and am going to make them communicate and hopefully make a working useful device however each require a voltage power supply (obviously) so that they can run. I am wondering, instead of having 2 9V batteries running 2 side by side chips, can i split the voltage of the 9V battery so that each can run off of the same battery? I wanted to consult this before I fry my boards. THANKS
