Alright, im suck in the world of Car PC's and have a unit that can control my A/C. But it uses a servo to pick the vent location and i just need like +5 for each postion. I know its confusing but ill try to explain it. If you click a button (VB program) it moves the servo to like 55 degrese, and different locations for each vent. I need a circuit that will interprate the Pulse width of a certain servo signal and output +5 to a pin on the chip. I am just not talented enough to do it. Let me know if you need any more clarification.
Why not just send a signal that isn't as long? That's basically what a PWM would be doing in effect. Can you not control the length of the "transmission"?
i have no control over the PWM signal, the board that has all that on there is already made by the person i bought it from, im just trying to adapt it to my situation.
