Greetings.
Beg your pardon for this noob question:
Reading Electronics Club explanation on sink and source for 555 IC gets me totally confused.
They write:
"If the IC is sinking current it is flowing into the output." -> I get this. But when they write, right after that: "This means that a device connected between the positive supply (+Vs) and the IC output will be switched on when the output is low" ->What??
This is one situation where, to me, talking about electricity according to Conventional or Electron current flow is NOT indifferent. Don't electrons go from 0V to Vs? If so, when the IC is sinking, electrons have to flow from 0V into the IC. Hence it is the device connected between the negative (0V) and the IC that should be switched on! Right?
Dear lord, and I thought I had it figured out at last...
Much obliged
