Hi
spec. Many thanks for your detailed reply - very much appreciated.
I've gone ahead and updated my profile to include my location. Good suggestion -yes in Australia, Melbourne.
Thanks for your answer to my questions. Great help.
I would like to press a switch (and release) and the pump is activated for X seconds. Press a second switch (and release) and the pump is active for Y seconds. Press another switch (and release) and the pump is active for A seconds. Press another switch (and release) and the pump is active for B seconds. Press another switch and the pump is active until I release the switch.
I would also like to control the speed of the pump, I think with a PWM is best.
Can I purchase a timer circuit to run (as programmed by a trimpot) for 0-20 seconds? I will purchase 4 of these, some switches and a PWM to run the circuit.
Thoughts? Links? Ideas? Advice?
Thanks in advance
