Not sure what you meant by "between 7V and 12V". Maximum input voltage is 5.5V. So try to get a voltage between 3v (minimal) and 5v, when providing a signal voltage between 12v and 14v. | |

| Oct 14, 2014 at 20:25 | comment | added | hanipman | Thanks. And Pin 7 is supposed to be the input signal wire. Messed that up in my code. And I was thinking more along the lines of wiring up a voltage divider to change the input voltage to somewhere between 7V and 12V | |
