A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals.There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an angle transducer. The output of an incremental encoder provides information about the motion of the shaft, which typically is processed elsewhere into information such as position, speed and distance.
Rotary encoders are used in a wide range of applications that require monitoring or control, or both, of mechanical systems, including industrial controls, robotics, photographic lenses, computer input devices such as optomechanical mice and trackballs, controlled stress rheometers, and rotating radar platforms.

I am trying to both design a code for Arduino and build a circuit connected with the Arduino which uses 3 anode 7 segment and 3 resistor arrays with 7 pins to connect to the Arduino Uno. The encoder is a rotary encoder. I have Pin A of the rotary encoder connected to pin 13 of the Arduino and...
I've been using DC motors with magnetic hall effect encoders on them to measure position control. It's basically a feedback servomotor system.
i've so far been feeding the signal into my microcontroller's interrupts. This has been causing some problems with my timers and program. Let's say the...
I apologize in advance if my post is in the wrong section.
I'm writing a program to control a stepper motor. The motor came with a motion controller and an encoder. I'm not sure how the encoder should be used. I can program the controller to set the "zero/reference" point and tell the stepper...

I can have the sensor on an interrupt, but how do I detect...

So I've been trying to read up a little on incremental encoders and have been looking at the outputted signals typically labeled A and B. These signals are 90 degrees out of phase. Apparently, the purpose of having both of these signals is for identifying motor direction. However, I'm kind of...
Hello, I need to design a circuit (3-bit priority encoder) whereby:
- if input X =1, then outputs B1=1, B0=1
- if inputs X=0, Y=1, then outputs B1=1, B0=0
- if inputs X=0, Y=0, Z=1 then outputs B1=0, B2=1
- if all 3 inputs = 0, then outputs B1=0, B0=0
Would this be the correct way to...
I have one quadrature encoder with A- A+ and B- B+ Signal, but my driver is a single-ended encoder channel?
Can i just connect either the A+ and B+ or A_ and B- signal to the single-ended encoder channel?
Please advise.

I was given the following question "An optical incremental encoder that produces 1,000 pulses per revolution is connected to the shaft of a motor. Determine the angular resolution of the encoder in degrees and the motor speed in RPM, if the encoder outputs 5,000 pulses

Hi,
as part of a project I needed a slim (<10mm) small diameter (<30mm) through hole absolute encoder that works at 100 degC. I wanted this to be able to determine a motorized valve position, so it needed to slip onto the gearbox output shaft between the motor and the valve.
Anyway, I...
Hi all. For a project I am doing, I need to find a motor with an encoder that we can use to detect the exact angular position of the shaft at any given point in time.
I'd like to see if there is any motor out there with absolute feedback from the encoder - i.e., that I would be able to read...
