Does anyone know if it is possible to start a program from the beginning of the loop() function after an external interrupt has been executed instead of picking up where it left off?
I have a program which checks the speed of the car, distance traveled, average speed etc.. and when the interrupt is activated, it is supposed to toggle through the different modes. The problem I have is that if the car is standing still and the magnets are not passing the reed switch, I need to wait 6 seconds for each screen to advance. I would like to make it so that it advances instantaneously and causing the program to start from the beginning of the loop after the interrupt has been tripped would do this. If anyone knows of another solution that would work, please let me know and so I could try that.
