Grove atomizer capacity and connections

Hi,
In my application, I would like to connect run atomizers at full capacity when 5V power is applied.
Will have I have to connect another pin to 5V ot connecting just power and gnd sufficient?
Also I would like to connect up to 6 in parallel. Will there be any issue with this?
Thanks in advance.

Did you run into a problem on the test? What is the phenomenon?

Hi , We will be connecting this week.
Not sure until we try.
Just wondering what proper connections should be made. Any other lines have to be pulled high?
