Hello peoples, I am working on an Arduino humidifier project and I have ordered some pre-assembled boards with atomizing/ultrasonic transducers off of Alibaba. Of course I was given these boards with no documentation or paperwork.
Two of the boards I ordered use 5V direct DC plug-in, which work perfectly.
The other bigger transducers are a bit more complicated to use for the first time so I decided to turn to these forums for some help.
I have attached some pictures of my boards and am hoping someone here can give me a hand with getting them started.
Since I am here if any of you have some basic information on working with these transducers I would love some extra help.
Thank you
