Im tryng the default and basic code from here :
https://playground.arduino.cc/Main/RotaryEncoders
My problem is that im always receiving new values, not just only when i moved the encoder.
im using an Arduino Mega, connecting the A and B to 52 and 53 pins. and the center of the encoder to the 5volts at is it indicated in the code.
I´ve tryed :
-Inverting the pins connecting A to 53 and B to 52.
-connecting the middle to GND.
I graficated the values in processing to look if I could find some kind of pattern,(the attached image).
this is my code wich is the standart code for encoder conections:
/* Read Quadrature Encoder
Connect Encoder to Pins encoder0PinA, encoder0PinB, and +5V.

*/
const int encoder0PinA = 52;
const int encoder0PinB = 53;
int encoder0Pos = 50;
int encoder0PinALast = LOW;
int n = LOW;
int num = 0;
void setup() {
pinMode (encoder0PinA, INPUT);
pinMode (encoder0PinB, INPUT);
Serial.begin (9600);
}
void loop() {
n = digitalRead(encoder0PinA);
if ((encoder0PinALast == LOW) && (n == HIGH)) {
if (digitalRead(encoder0PinB) == LOW) {
encoder0Pos--;
} else {
encoder0Pos++;
}
Serial.print (encoder0Pos);
Serial.print ("/");
}
encoder0PinALast = n;
}
any suggestions would be greatly aprecciated, thanks !
