Hi
I have placed a diode in series to the + of a DC jack to provide reverse polarity protection for my circuit.
To test if it works, I set a wall wart to the reverse polarity. My circuit did not fry and can work using a 2nd wall wart set at the right polarity.
Why a 2nd wall wart? Because it seems that my first my wall wart is now not working!! (it was working earlier before this test).
Is this normal? Why?![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Thks!
