Inspired by the all new 2009 Acura TL (I work at an Acura Dealership), I decided I want to re-create the keyless access system featured in this new car. The system eliminates the need to use a key when starting the vehicle . If you would like to help me do this, please feel free to read my post. If not, try not to waste your time because it will probably take me quite a bit of typing to explain everything.
The Acura system uses a transponder in the key fob to detect when the owner of the car enters it. You can keep the key fob right in your pocket. Then, Pressing the stop/start button once turns on Accessory mode. Pressing it again turns on the ignition. Pressing the stop/start button again while depressing the brake pedal starts the engine. Or, for a quick start: Get in, depress the brake and press the stop/start once and it will go straight to starting the engine. Pressing the stop/start button while the engine is running shuts everything down.
My car is a 92 Integra. I am very familiar with Automotive electrical systems, and I am trying to learn electronics. So far, I only know the basics (ie: resistors, transistors, capacitors, relays, diodes, voltage drop, current, etc etc.). I've purchased and built a Junebug from Blueroomelectronics to learn more, but I still don't have any code writing skills. I'm hoping the code required for this project will be relatively simple.
So, I thought a good place to start would be to learn how to make the LED's on the junebug respond to the three buttons similar to the way the Keyless Access System works:
Button 1= simulate input from proximity detector (already purchased one)
Button 2= simulate Stop/Start Button input
Button 3= simulate Brake Sw input
And the LED's would simulate the output to the three 5v relays that would be used the activate three 12v automotive relays mounted under the dashboard of the car. They would have to respond as follows...
-Button one must be held to do anything
-Pressing Button 2 lights an LED.
-Pressing Button 2 again lights a second LED
-Pressing Button 2 again lights a third LED for approx 7 seconds
-Pressing Button 2 again shuts all lights off
-If Button 2 and 3 are pressed at the same time, the first and second LEDs should light for 1 second, followed by the third lighting for 7 seconds
-Letting go of Button 1 at any point shuts everything down
If I can accomplish this, I'll be on a solid path to making this system work. Now I don't need the code written for me (unless you want to, I'll study it! lol) But I need a LOT of guidance.
I downloaded Swordfish and printed the reference guide to keep on hand. I know I'm semi-close to understanding the code, but all I can do to the "blinky" code is make the LEDs run faster or slower, lol.

Any and all help is GREATLY appreciated. Thanks in advance guys!!!!!
