I was thinking about using a hexadecimal control switch and ended up pondering what alternatives exist. For example, how about a quadrature encoder and an up-down counter. There appear to be a couple ...

If you are a novice to rotary encoders for human-machine interface, there is a potential pit-fall. Otherwise called quadrature encoders, they deliver two-bit gray-scale binary on rotation, with the ...
