AZDelivery 3 x KY-040 Drehwinkelgeber Drehgeber Rotary Encoder Modul compatible with Arduino Including E-Book!

AZDelivery - Your expert for microelectronics Application examples Use the rotary knob as a motor regulator, as a volume control or as a menu control for a microcontroller. The digital potentiometer for your project: With our KY-040 Rotary Encoder you can navigate through your homemade menu items or even control speeds. Unlike analog potentiometers, the angle of rotation is not limited. In practical modular design. With extra switching contact! Connections: "GND" = ground connection; " " = 5V power supply; "SW" = break for push button; "DT" = encoder pin B; "CLK" = encoder pin A Rotation readout: The encoder gives the signal for rotation on pin "CLK" and "DT". It is decisive which pin changes state first. When turning clockwise, "CLK" first changes status. When turning counterclockwise, "DT" first changes state. Use of the push button: The pin "SW" gives a high impulse when the dial is pressed. Pin assignment microcontroller: CLK=[Pin 3] DT=[Pin 4] Button=[Pin 5] =[Pin 5V] GND=[Pin GND] Pin Assignment Raspberry Pi: CLK=GPIO16 [Pin 36] DT=GPIO15 [Pin 10] SW=GPIO14 [Pin 8] =3.3V [Pin 1] GND=Ground [Pin 6] TECHNICAL DATA Chip: KY-040 Operating voltage: 5V Step size: 20 positions/revolution Welcome to the AZDelivery family!
