It is widely used for volume adjustment, parameter setting, speed regulation and menu selection for Arduino, single-chip microcomputer and other control projects. It has multiple configurable options: forward code for clockwise rotation or reverse code for counter-clockwise rotation; two shaft styles including D-type half-round shaft and knurled flower shaft; available shaft lengths: 10mm, 12mm, 15mm, 20mm. Two pulse specifications are optional: 15 pulses with 30 positioning points, or 20 pulses with 20 positioning points. The encoder works at DC 5V, outputs A and B quadrature signals to identify rotation direction and rotation count. External pull-up resistors and filter capacitors can be connected according to the wiring diagram for stable signal output. Suitable for DIY controller, audio equipment, instrument panel, digital display, motor speed control and electronic experiment projects.\u003c\/p\u003e\n\u003ch2\u003eAttribute
