Hi, I'd like to completely isolate logic circuit (arduino) from the devices controlled by it. I know I can use ULN2803A IC and it almost cuts it as far as its rating is concerned (correct me if I am wrong, but it contains eight Darlington Drivers and each of these can provide up to 0.5A, right ? t…
