+Controls the motor and sensor of the stock navigation display on the 2001 to 2008 Mazda 6. Replacing the stock screen controller functionality with a customizable one using off the shelve parts.
 
 This is useful if you want to use the stock navigation enclosure with a tablet and want to retain the same buttons and functionality of the original screen.
 
-This code can be used for controlling the RX-8 navigation screen as well. ( modify tresholds for open, closed and tilted positions)

+Schematic
+---------
+Don't remember much about it, but here is the general idea:
 
-The circuit:
+![schematic](docs/schematic.png)
 * 2 pushbuttons attached from pin 2 and 3 to GND (use existing buttons on Mazda 6 input screen / RX-8 buttons)
 * 1 BA6209 H-Bridge for controlling the motor with its inputs attached to pin 4 and 5.
 * 1 Potentiometer to control position. (included in stock nav enclosure) conected to analog pin 0
-* 1 Motor (included in stock nav enclosure)
+* 1 Motor (included in stock nav enclosure attached to output of H-Bridge)
+* 12v and Ignition should be wired in as well, the idea is that when the car turns off the ignition voltage drops to 0 telling the arduino to initiate the close operation.

-Update; 10/24/2014
-I'm pleased to report the code has been working great so far. I've been using it for months already without running into issues.
+#### Update: 1/6/2021
 
-Although, from the experience I have learned that a better circuit needs to be made to avoid wasting power. With that in mind, implementing the sleep functionality into the Arduino is my next step. In the hopes of reducing its power consumption.
+It's been a long time...
+Unfortunately I wasn't able to continue working on this project. I have since moved abroad and unfortunately had to sell my car. 
 
-Through testing I have discovered it wastes ~90mA while being powered on. It looks like nothing, but consider that the whole car uses only about ~40mA while off!!
+I'll leave this project here in hopes somebody else is interested in thinkering with their Mazdas. There is a "fullish" write up in my [blog](https://blog.alejandro.md/2014/09/01/in-car-tablet-install-part-1/).

+Through testing I have discovered it uses about ~90mA while powered on. Seems like nothing, but considering that the car alone uses about ~40mA while turned off, its something to keep in mind while storing your car for longer periods of time.
 
 Happy driving!
