Hi all,
I am trying to control a air pump based on the feedback from a pressure sensor. I am new to Arduino and would appreciate any help.
Have You tried Googling on Air pump?
We can better help if you tell us what you have in more detail. We can't see your project so all we can know is what you tell us. Can you read the pressure transducer? Can you control the pump?
Post the code that you have, describe what the code actually does and how that coffee from what you want.
if you find the pressure gauge is very noisy, you might need to run the pump, then shut it off, then allow the reading to stabilize.
my tire pump reads 34 PSI when the pump is running and 31.6 after it shuts off.
BTW, here in the US, it is almost winter so, now is a good time to think about putting winter air in your tires.
What range of pressures are you interested in?
Have you chosen a pressure transducer yet? If not, I recommend one with an I2C interface and which runs on 5V.
If you want to be able to let out air you will probably need to control a separate valve.
