sa main elcl.. gusto mo pagoff/on ung isa, ganun din ung isa.. tama ba? kung ganun, edi sa main nga.. kung linear ps gamit mo, edi bago dumating ng transfomers  |

^ agree.
na-state mo naman na buhay pa rin 'yung MCU kapag nasa motor 'yung switch, doon na lang kung saan nagsimula 'yung dalawang supply.

^ it's a quick solution, but it's not the best. in practical situations, bihira kang makakita ng pinaghihiwalay pa 'yung battery ng motor at battery ng control. tulad ng sa kotse, it's a very noisy environment pero lahat ng electronics sa iisang baterya pa rin nakakabit.

gamit mo ba 78xx na regulator? kung oo, baka naman nahahatak ng motor mo yung 1A na max current ng mga 78xx regulators..
