 ===== Hardware Modifications =====
-The rotary encoders I bought appeared to have resistors of 10k in series with the rotary contact (value of R in picture above). After replacing these resistors to 501 Ohm, the readings improved significantly.
+The rotary encoders I bought appeared to have four 10K resistors in series with the rotary contact (value of R in picture above). After replacing the following resistor pairs, the readings improved significantly.
-The positions for S1 and S2 contacts on the back of the encoder are marked with red circles in the first image.
+  * Pull-down resistors from 10K --> to 501 Ohm, The positions for S1 and S2 contacts on the back of the encoder are marked with red circles in the first image.
+  * Pull-up resistors from 10K --> to 4,7K Ohm.
