Can someone give a quick lesson on how to attach these? https://docs.google.com/viewer?a=v&...&sig=AHIEtbQG40OOwTtp3rL6whUWgh8OGrU-rw&pli=1
You can't use a BC 547 in that circuit since it is an NPN which requires the opposite signal polarity from the BC 547 which is a PNP. You need a PNP. Just about any small signal PNP will work.Here is part of the schematic I'm trying to copy. I'm using BC 547 instead of the BC 557.
