Auto Canceling Turn Signals
I was thinking that automatically canceling turn signals might be pretty handy. Of course, I have never forgotten to turn my signals off. :smilewinkgrin:
So, to that end, I designed a circuit around a PIC micro-controller and now have auto canceling turn signals. There is a little more involved than with a car. Other canceling methods besides a steering wheel must be found. I decided one way to do it would be to use speed, acceleration, and deceleration as parameters.
The unit is dynamic, not passive. It continually monitors speed in miles per hour. Acceleration and deceleration are also monitored. The program uses these to determine when to cancel or not to cancel the signals. If desired, the signals can also be canceled manually.
It was a fun little project. Now that I have auto canceling signals, I'm finding them quite a convenience.
