I am building 3D printed keyboard. I am probably going to use some off-brand cherry MX switches (probably outemu switches). Since mechanical keys simply allow current when pressed in, I do not need a resistor to protect the key switch.
So my question is “do I need a resistor for a keyboard key switch?”
And each output from the matrix will go into the input on an arduino.
I think I got my answer, dim. The switch itself doesn’t need a resistor. But the Arduino might. Thanks all who had input. Much appreciated
