i want to use a computer(laptop or tablet) to display the things normally displayed on the car instrument panel(coolant temp, oil pressure, turn signals, etc.) on the computer screen as a picture of a round gauges and/or digital number readout. be able to place these on the computer screen in various sizes and locations. is this easily accomplished, or is the task very lengthy and difficult?
If you have a modern car with an OBD port its quite possible. Search for "arduino obd" or "raspberry pi obd" for examples of what can be done.
Thanks
