Q & A
The KY-040 Rotary encoder module is designed so that a low is an output when the switches are closed and a high when the switches are open.
The low is generated by placing a ground at Pin C and passing it to the CLK and DT pins when switches are closed.
The high is generated with a 5V supply input and pull-up resistors, such that CLK This website uses cookies to enhance your experience. By continuing to visit this and DT are both high when switches are open.
 If you push on the shaft, a normally open switch will close. The feature is useful if you want to change the switch function. For example, you may wish to have the ability to between coarse and fine adjustments.
