I need to control the speed of an EC fan using an Arduino and suitable components. The plan is to hook an an Arduino Uno and control the speed with either 0-10V analog input or PWM. I was hoping to use some type of digital potentiometer or try to create suitable PWM signal. Later on I need to wireless control the speed either with Wifi or Bluetooth connectivity so an regular potentiometer is a no go.
EC FAN: 230V, controlled with either 0-10V or PWM (1…10kHz)
I’ve attached the control diagram and control method. I would really appreciate you guys advice what is best way of doing this for an beginner like me?
- Arduino Uno
- ACtoDC (12V) adapter
- All suggestions appreciated
