thanks.. I'll update them now..


that was always something I get confused on..

the NPN vs PNP... (as well as the whole current sourcing vs current sinking..etc..)

I have only used one a few times as a simple switch..




update:

images updated to show NPN or PNP type resistor to match correct diagram


(thanks Grumpy Mike)
