I have an project, that got has an motor that is working to pump little drops, from time to time..
but meanwhile, sometimes works, others don´t... have to increase the amount of power...
the pumping is working with analogWrite (pin, 55);
but other times, the pump only work (start pumping) with 65, otherwise only will make noise to start , and this way is not acurated at all..
Already make two 1uf ceramic capacitor attached to pump and wires...
what is the best way to get this working?
any ideas is very welcome,
It sounds like the amount of static friction varies as the shaft turns, so sometimes more current is needed to get it
moving - suggest driving at about 80 for 1/10 of a second, then drop down to 55 or whatever - the initial extra pulse
should overcome static friction, then you backoff the drive to prevent it running too fast.
But I might be wrong - more details of the set up might help.
tks MarkT
i really had think something similar, but like 5mills.. (will try with more)
is an simple sketch.. (like blink led with analog 55, on and off), but just want that work with the slower possible power.. for long times off and on just 5 sec...
this is more than code, once have more to do with electric power (12v) and mini motor.. already searched for noise reduction and so.. and put 2 ceramic cap..
