Hi guys, I was wondering if you could help me out on a little circuit problem. I want to start moving towards the ATTiny chips for some of my smaller projects. However, being clumsy as I am, sometimes I do the pinout backwards when there's Dsub's involved since the pinouts are in reverse when lookin…
