two questions about a schematic i'm building for a friend

ok. firstly, the batteries… i drew in red how i would connect them. you can see how the power source isn’t clearly labeled on this schematic. but is what i drew in red correct?

also, input voltage goes to the chip… and input ground should go to ground like i drew as well?

thank you very much for any help with this

Yes the parts drawn in red are correct. :slight_smile:

awesomeness. thank you
