Car turn signal monitor

Hi,

I am interested in developing a very simple car turn signal monitoring interface. The idea is to monitor a novice driver he/she is using the turn signal correctly before actually making the turn. It should something to sense the turn signal left or right (direct hook to the turn indicator light itself or line etc) and then the way the car turn right or left from an accelerometer or some sensor device.

Appreciate any help.

Thank you

What happens when you indicate left in order to signal your intention to turn left after the right hand bend up ahead?

Lurch, that is a very good question. This is a bit complicated thinking. I this case, I call it preemptive signalling, may need additional input from GPS or terrain data to validate indeed there was a bent before the turn and the final action of the driver and the signal should be considered. Also the speed of the car, the distance between these turns are all need to be considered for such complex scenarios.

I still looking for advise on what type of Arduino should be good for this purpose.

Thank you
