Encoder giving value between steps
I'm trying to interface an encoder and a 1602 i2c display. My encoder seems to be giving an output between steps.
I have tried to make my code as simple as possible and am outputting whether the encoder rotated clockwise or counter clockwise to…

If statement behaves erratically
I connected the output from an encoder motor to int0. this is used to increment a counter at every pulse. in the loop(), I check this counter and stops the motor if it is above certain value. But this "if statement" works erratically. The while loop…

Sampling rate issue
I have an Arduino code which runs decently.
// Read in 10-bits Magnetic Encoder AEAT-6010-A06 into Arduino Uno
// Sampling
// Declarate
const int CSn = 4; // Chip select
const int CLK = 7; // Clock signal
const int DO = 8; // Digital Output from…

unexpected behaviour of encoder with increasing rpm
I am using a DC motor with encoder, and I am trying to calculate how many pulses are recorded in every one second interval. (note that the power source is of 12V for the motor)
Circuit and code:
int encpin=3;
volatile long npc=0; //new pulse…

KY-040 rotary encoder skipping steps
Yesterday I asked a question about de-bouncing this rotary encoder and Jsotola suggested that I should use a method like This to detect the previous state and then do the counting. using that method each turn is counting twice in one turn so I came…

Rotary Encoder gives "wrong" patterns?
I am trying to learn how to use a Rotary Encoder together with an LCD display where I can use the encoder to choose Letters that will be printed in the LCD.
This is the kind of result I should be getting, but instead I am getting this:
1 2 3 4 …

How do I read a sub-degree angle?
I need to measure (and record changes over a short time) the angle of a lever at a sub-degree resolution (The fulcrum can be the sensor) using an Arduino.
I've looked at rotary encoders, but even those with no detents have about 24 pulses per…

Problem to convert rotary encoder output to angle
I'm using this incremental rotary encoder with a rotating disc.
Here is my system:
I will explain the system briefly and above is the illustration for that:
The rotary encoder(blue) is attached/fixed to a larger disc(yellow) concentrically at its…

Undocumented industrial servo with 8-wire encoder: how to read this encoder?
I have scavenged an industrial servo with its attached ballscrew linear actuator from an old large format scanner, and I am trying to figure out how to make a 'servo drive' aka 'servo driver' aka 'servo controller'.
I'm a total novice at arduino,…

How to get the encoder position while the rotary motor is moving
I have a question with encoder and the rotary motor. When the motor is moving, I can't access the position of the motor. I have run the code separately, it is perfectly fine. But when I combine, these two codes, the motor is able to move but there…

Arduino Rotary Encoder Pulses?
I made an program so if I turn on my rotary encoder the position and the rotation comes on a LCD screen. But I need to change it a bit up for my teacher, she wants to see the graph of the pulses on the serial monitor. I searched it up and can't find…

Basic doubt regarding encoders with Arduino
I created a program that measures the pulses set out by the encoder (part of the dc motor with encoder inbuilt), and uses the ppr value (pulses per rotation) to calculate the rotations per minute (rpm)
However, the serial monitor continuously shows…
