Rated 4 out of 5 by from Round and Round Nifty little thing, perhaps underrated these rotary switches. O/P Read by an Arduino easily. Combine multiple drive outputs with diodes after the return lines for crude multiplexing. 2 of these can then be read with 6 lines, 4 with 8 lines. Why bother with a screen. Only -ve is less than stellar build quality.
