Howdy, i am brand new here. I know very very very very little about electronics. I'm tryibng to figure out how to make a regulator or transformer or whatever you call it that will take a +5VDC input current and stap it down to a solid +3.5VDC output current. can i use a resistor or something, or do i need to build an elaborate circuit? please help me! i will need a schematic drawn for it, if you tell me to "use a in34a diode soldered to a 3v resistor" i won't know what you mean! i know very little!
