Encoder VS a-picture-is-worth-a-1000-words

This project uses interrupts for the encoder. It uses the "Encoder" library mentioned in another comment.

I can't really come up with any good illustrations for something complex off the top of my head, so I'll go for a really simple one. In fact, that's part of it's beauty.

When I had to deal with the signals from a rotary encoder the first time (being a programmer with two left hands and zero hardware affinity), I had a look at a couple of C libraries but didn't have the patience to slog through their implementations in order to understand what signals they were decoding.

...until I saw this: https://github.com/PaulStoffregen/Encoder/blob/master/Encode...

I'm not sure if it was this exact library, but that's the comment I saw. Nice and obvious, in contrast to all the obscure attempts to convey what was happening all the other libs made through prose comments.

Search for quadrature encoder for Arduino (there is a library for that). Your motor has pin 1 and 2 as encoder output.

According to people who are more knowledgeable than I on this, encoders can be ran through 2 interrupt pins for best performance, but also just a single interrupt pin and still get decent performance on the encoder.

connect both X1 and X2 to digital pins and try the encoder library https://www.pjrc.com/teensy/td_libs_Encoder.html

// Using PaulStoffregen/Encoder // https://github.com/PaulStoffregen/Encoder #include Encoder encoder(CLK_PIN, DATA_PIN); void read_encoder() { const int TempIncrement = 10; // Temperature change per encoder increment const int TempMin = 0; const int TempMax = 315; // Get the current position of the encoder, then reset its // position back to 0 const int pos = (int) encoder.readAndReset(); // Calculate the change in temperature const int NewTemp = (pos * TempIncrement) + set_temperature; set_temperature = constrain(NewTemp, TempMin, TempMax); #ifdef __DEBUG__ Serial.println(set_temperature); // print the set temperature value on the serial monitor window #endif // v Unchanged v if ( digitalRead(SW_PIN) == LOW) //If we detect LOW signal, button is pressed { if ( millis() - debounce > 80) { //debounce delay encoder_btn_count++; // Increment the values if (encoder_btn_count > 2) encoder_btn_count = 1; #ifdef __DEBUG__ Serial.println(encoder_btn_count); #endif } debounce = millis(); // update the time variable } }

This might be helpful.

Have you tried: https://www.arduino.cc/reference/en/libraries/encoder/ You could also try: https://www.pjrc.com/teensy/td_libs_Encoder.html

Specially the git-purr one that explains git.

git clone https://github.com/girliemac/a-picture-is-worth-a-1000-words.git

I think what this needs is a proper scan and vectorization.

Author has a nice repo with other doodles:

I really wish there were some way to find and navigate good OERs like these.
