Project 7 - Musical Keyboard: Resistor Question
good day,
in project 7, we're introduced concept of resistor ladder. each switch along ladder fed power through resistor, each of varying resistance. question regards orientation of these resistors:
according instructions, gold band of each resistor (the tail) faces power in, while head directed toward switch. think since direction of current power in switch, tail end should face switch.
why opposite?
directions:
(+) -||||- (switch) - (-)
expectation:
(+) -||||- (switch) - (-)

it not matter. resistors bi-directional.
