Hi guys! Today we are going to make ''Keyless-GO system'' with 2 arduino.

Why 2 Arduino? We could with only 1 Arduino.

-We decided to 2 arduino s more safer than 1 arduino. Because thiefs can broke one of thems' system and they can start up it. But if we use 2 arduino , one of them will key of other. and when they broke the first ones system, they will locked. I hope you understand this situation..:)

Okey, Let's Start!

PLEASE FOLLOW ME AND VOTE MY PROJECTS FOR MORE USEFUL PROJECTS. THANK YOU..:)

Step 1: What Parts Will We Use?

1- 2 x Arduino

2- Potantiometer

3- L298N Motor Driverr

4- Rfid Card Reader(RC522)

5- A Motor(only for prototype)

Step 2: Logic and Usege;

Logic is;

When you want to start up your car and turn the key, key says ''1''. If you do not run key says ''0''

The first arduino (uno in my video) is instead of the key. And when you put on the card, it says ''1''. When you take over the card from RC522 Arduino says ''0''.

WARNING; MOTORIZED ARDUINO IS INSTEAD OF THE CARS' KEY INPUT PORT.!!

Step 3: Connections;

You can see in the picture, black and purple cables are energy connections of other Arduino. So you have to connect D7 to other arduinos' 5V pin and same as GND.

Step 4: Codes Link;

WARNING; First of all; you must upload the ''EEPROM-TASK'' to your arduino for saving the id cards (you can save 2 cards). Then you must upload the ''TASK'' code to your first Arduino.

After that you can upload the second code to motorized arduino ''surucu'' codes.
