Hi, I'm trying to make an Arduino based device which goes plugged to the power outlet.
I'm repurposing one of those "USB outlet" cell phone chargers (like the one in the pic) since I have a lot of them.
But there is a problem: If I plug the charger, and then the arduino, everything works perfect. But, if I connect first the arduino to the charger, and then to the power outlet, the arduino won't start until the reset button is pushed.
I've tried to solve it adding a delay in the void setup() hoping that it allows some "power stabilization" (I know, not even me buy this BS)
I was thinking in some kind of capacitor in order to delay the power feed (is it even worst BS?)
thanks for reading!
