 Bigger Bigger  Smaller Smaller  Reset Reset

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..


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

(thanks Grumpy Mike)
