Hello, I've set up a simple circuit that turns on a humidifier when the humidity of the air drops below 80%. However, I'm having an issue with the vapour coming out of the humidifier being much less powerful, when powered via the arduino, than if it were to be directly powered via the standard micro usb port.
Through research, I think that this issue is because of the current not being regulated properly. Would I need a MOSFET or transistor to solve this? And if so, how should I go about setting it up?
I've added a pic of the current setup.
