Frankly speaking, I do not want to work too much regarding rotary encoder sketch as it is well documented elsewhere. However, one of my most rewarding RT project is on the way to you. Hopefully you ...

byte enc1oldPins = 0; // will hold state of pins last time encoder was read byte enc2oldPins = 0; byte enc1newPins = 0; // will hold new encoder pin reading, to be compared with last time's pin states ...

Taste The Code. How to Use Rotary Encoders and Interrupts With Your Arduino Projects. Posted: June 10, 2025 | Last updated: June 10, 2025. Hi, I'm Bill.

Rotary Encoder: Used for adjusting the frequency and amplitude of the generated signals. 3. LCD Display : To show the current settings and status of the function generator.

For example, HP inkjet printers have a quadrature encoder that consists of 150 lines per inch ruled on a mylar strip. So that is a line about 1/300 inch wide followed by a space about 1/300 inch.
