Go Down  Topic: How to use sensor signal trigger/stop code
execution? (Read 384 times) previous topic - next topic   Hi I
am very new to Arduino, so please excuse the simplicity of my
question.  I try to do this: Read 1st. Proximity sensor signal,
then trigger/start my code execution, once get 2nd. Proximity
sensor signal, then stop my code execution, and do something
else, such as rotate stepper motor 500 rev.  Could somebody give
me similar example to achieve this?  Thanks very much in
advance.   You need a state variable:  Code: [Select]  byte
started = 0  if sensor is triggered then  started = 1 - started
if started then  do stuff that doesn't use large delays()   Go
