INCORRECTu1 u3 are not opto-isolatorsAPPROVED
CORRECTU1 and U3 are optoisolators http://pdf1.alldatasheet.com/datasheet-pdf/view/3041/MOTOROLA/H11L1.htmlAPPROVED
CORRECTDo you believe that other guy? Of course theyre opto-isolators. A 12 year old would know that... Its Electronics 101 / Day One. At least in the U.S. it is. I dont know where the mongoloid is currently located... But I believe they covered opto-isolators in my grandmothers 3-day basic household technology class that she attended recently to gain a better understanding of microcontrollers. I would kid her about being an imbecile for not knowing more about some of her kitchen appliances.APPROVED
CORRECTLooks correct, but why dont you use only one type optoisolators APPROVED
