Hi guys! Thanks in advance for the precious help.
I'm trying to get a 12v source from a quick charge wall charger (can supply 5v; 9v; 12v ... depending on the connected device). D+ and D- USB' pin are used to set the charger' output voltage.
I found that applying a voltage of 0,7v on D+ and after 1 second the same 0,7v on D- actually works and the charger switch from 5v output to 12v output.
The problem is that i'm not able to make an automatic circuit to delay the 0,7v on D- pin.
All i need so it's a simple circuit that starting from 0v goes to 0,7v after about 1sec. Would it be possible?
