Hello everyone. I would like to help me find a video about testing-counting circuits if you can. I am having practical exams next week but i havent practiced enough cause i dont have the right equipment available. That's why i was trying to find videos about using a multimeter or pulse meter to find problems in the circuits. But.... i failed so i am asking your help. if you know any video that can help me please post it. thank you for your time and sorry for my english.
