Low cost OBD2 communications on K-line

Low cost OBD2 communications on K-line

RichardvdK @ instructables.com shows us how to use OBD port of your vehicle to push data on a LCD screen. To achieve that he used a 16F886 microcontroller and some common electronics parts.

This is just another OBD2 solution for monitoring the sensors in a vehicle. It supports the K-line OBD2 serial communication between a vehicle and a microcontroller. This K-line communication is also known as ISO 9141-2 or ISO 14230-4 (also known as Keyword Protocol 2000 or KWP). Both ISO’s are almost similar. This solution differs from the rest that is low cost. It is low cost in the way that you don’t need an arduino, raspberry pi or smart phone. Just a microcontroller and LCD display so you can use your smartphone for other purposes.
