Hi Tom,
It sounds toooooo simiple.
One input
two internal timers
one output.
BS1 will handle this with no problem unless you want to make it
really fancy.
A person of your capabilities ....
-can ask a question
-can word it logically
-can access the internet
-can follow instruciotns (going from SRG to this list)
-and can inteurpet things that are new.
you should be able to write a Stamp program in short order and have
fun while learning how to program.
if you want some ideas, conisdder a 4 second push and hold. hold the
button for over 4 seconds and it would enter another mode, like an
override.
add a beeper so you know what is happening.
that way, you could override the unit and get a longer run time....
possibly have it turn on in half cycles if the button is pressed
repeatedly... kinda like if you hit it 3 ties in 30 seconds, you can
get a 5 minute run starting now, regardless of when it was last off.
possibly a 5 push off so that 5 pushes in 5 seconds allows you to
stop shut off the valve.
