I have a HDMI switch that I want to control with an Arduino. It's working by pressing a button to change input signal. The button is NC(Normally Close). By pressing the button you break the 3.3V going throw it.
I want so when you send 5V from Arduino you to break the switch of the 3.3V. What component is best for doing this? Will a transistor work? Doesn't it mean I need to apply 5V all the time except when breaking the switch.(Don't want that)
- Is there any MOSFET that will work?
- I have been looking at CMOS 4066?, is that a good IC for the job?
- Or is there any relay IC that work?
