I have a project that calls to use a water atomizer that uses an ultrasonic transducer. It needs to be able to essentially adjust not just turn on and off but the intensity of the mist. How do I do this? Will getting the grove board, https://wiki.seeedstudio.com/Grove-Water_Atomization/#application-ideas, and pwm the signal pin work? Or do I have to design my own circuit?
No, this one doesn’t need PMW just a high level to work, and you don’t need to draw your own circuit board. @Beryl_Artman
That doesn’t help me. Let me be more clear, I want to be able to adjust the rate of mist that is emitted(how much is coming out), how do I accomplish this?
I’m really sorry, I checked the schematic diagram, and this can really condition the fog speed through PWM. @Beryl_Artman
Hi, I would like to use this at max speed. What connections are required? Do I need to connect PWM to 5V constant voltage?
Hi Baozhu,
My question is similar but in my case , I want to be able to maintain at full fog speed without a controller board. Do I need to connect the PWM at 5V or leave it unconnected?
Thanks,
Don
