The Bourns Absolute Encoder is a digital control knob that provides 128 unique results evenly spaced around a full circle. It is designed as a control panel knob but can be adapted for other uses. This can be a good alternative to using a potentiometer and analog pin, as this allows for full-turn and multi-turn operation. It differs from the more common incremental rotary encoder which has only two or four values in a rotation and is designed to measure full rotations and direction. This...

Knob G Click features a combination of high-quality quadrature rotary encoder, and a LED ring composed of 24 individual green LEDs. Outputs of the rotary encoder are processed by a debouncing circuitry, which ensures reliable switching action, making the encoder directly usable in interrupt service routines (ISR) without the need for a bulky debouncing code. The 24-segment LED ring is driven by an advanced and flexible LED driver IC, which can dim each LED individually, allowing various...

MIKROE Counter Click carries an LS7366R 32-bit quadrature counter. The top of the board has a pinout for interfacing with incremental encoders. The interface has ENCA and ENCB pins, along with ENCI,...

MIKROE Counter Click carries an LS7366R 32-bit quadrature counter. The top of the board has a pinout for interfacing with incremental encoders. The interface has ENCA and ENCB pins, along with ENCI, which is a programmable index. The A and B pulses fron an encoder are out of phase to each other, ideally by 90º. The LS7366R CMOS counter takes these signals as inputs and decodes them for determining direction and speed. On the other side, Counter Click communicates with the target board...

This is a 12-step rotary encoder with a nice 'clicking' feel. It's breadboard friendly, and has a pretty handy select switch (by pushing in on the knob). The encoder is different from a potentiometer in that an encoder has full rotation without limits. The unit outputs gray code so that you can tell how much and in which direction the encoder has been turned. This unit does not come with a knob, but a working knob is related below.

Item #: COM-11102 -
Price: $97.66
Sparkfun

This 1024 pulse per rotation rotary encoder outputs gray code which you can interpret using a microcontroller and find out which direction the shaft is turning and by how much. This allows you to...

This 1024 pulse per rotation rotary encoder outputs gray code which you can interpret using a microcontroller and find out which direction the shaft is turning and by how much. This allows you to add feedback to motor control systems. Encoders of this kind are often used in balancing robots and dead reckoning navigation but it could also be used as a very precise input knob. Features: Resolution: 1024 Pulse/Rotation Input Voltage: 5 - 12VDC Maximum Rotating Speed: 6000rpm Allowable Radial...

This 200 pulse per rotation single-output encoder outputs electrical pulses which you can interpret using a microcontroller to find the position of the input shaft. This allows you to add feedback to motor control systems. Encoders of this kind are often used in balancing robots and dead reckoning navigation. The encoder comes with a set screw coupler which will attach to any 4mm shaft. Features: Resolution: 200 Pulse/Rotation Input Voltage: 5 - 12VDC Maximum Rotating Speed: 5000rpm Allowable...

Rotary encoders can be used similarly to potentiometers. The difference being that an encoder has full rotation without limits (It just goes round and round). They output gray code so that you can tell how much and in which direction the encoder has been turned. They're great for navigating menu screens and things like that. This encoder is especially cool because it has a common anode RGB LED built in, as well as a push-button. This version has an updated material that is heat resistant and...
