Hi Folks
getting there but now i have run into a timer loop.
first run works fine and code compiles ok.
but last three segments call a IF function that already true due to the prior run.
would like to know where to look or how to reset or stop at end of successful run
Thanks in anticipation
Gate 1.2
/*
Made to run on Arduino uno clone
this code is to run linear actuators with out position sensors
but have inbuild stop switches in actuators
to be used as auto gate openers
useing 2 H bridge units to drive
delay time is to allow sufficent run time to open or close gates
overrun is not a concern as actuators stop at limits
