I have just entered the world of Arduino and I am as green as they come, so be gentle with me and assume I have zero knowledge (cause that is what I have!)
I have tried to follow this video Arduino Nano Project! | Relay Control By Push-Button Using Arduino Nano! - YouTube
I have carefully rewired it time after time, but it never works.
How do I know to use the 3.0 or 3.0+ driver?
Maybe when I soldered the pin connectors I did not get them all good?
How can I verify that the nano is actually working properly?
When I connect it to my computer the POW light comes on and the L light flashes rapidly for a few seconds then changes to a slow flash.
Maybe someone could post a very simple sketch and wiring diagram to help me insure my board is working properly?
So you know what components I have at my disposal, I also have the Elegoo Mega 2560 Project set
