I thought this might be of interest to the group.
I have been using different rotary encoders over the years for diferent projects and perhaps the following info may be of help.
I have included a photo of the type I am referring to as "rotary encoder.jpg" in the files section.
It is marked with the name 'KEYES' but can be found 'unbranded' on several Chinese sites. To the UK they come in at less than ?4 for 10 of them.
The encoder on this pcb requires a 5V supply and will not work simply with reference to the digital input levels on the Arduino pins.
The connections needed for it to work are as follows, referring to the print on the encoder pcb and the print on the multiway connector on the project motherboard.
CLK --> pin marked 2 on board (yellow section of pins)
DT ----> pin marked 3 on board (yellow section of pins)
SW ---> pin marked 7 on board (yellow section of pins)
?+? -----)> 5V (any one will do)
GND -----> G (any one will do)
all the best
