when you rotate them you will feel a bump (known as steps), and most RTs have about 12 of these per rotation (some have 24 or more). Basically this step is the minimum amount you can rotate the encoder to register any change.

If you use the interrupt, you need to connect the encoder's CLK pin to an Arduino pin that can handle interrupts. But remember, not all Arduino pins can do this. For example, on the Arduino Uno, only pins 2 and 3 can work with interrupts. ...
I am confused as to whether the PCINT0_vect ISR is running just when PCINT0 is triggered, or when any port B interrupt that happens to be turned on is triggered. I am trying to control 4 encoders with one 328, so I would have 8 inputs that would need to trigger 4 ISRs. Alterna...
They are great fun and very useful and they even come with a couple of speed encoder disks (those little black circles full of holes). Problem is, no one tells you how to use them! Let’s resolve that and build a robot car with speed sensors. Along the way we’ll learn how to ...
Aside: I foundthis Gammon forum thread listing technical detail on ATmega328 interrupt service routines, which laid out work just for ISR overhead that would take 5.125us before any ISR code actually runs. This puts a hard upper bound of ~200 kHz on response rate of an ISR that does nothi...
They take to much time to be run inside the interrupt. You can add 1-2 directly connected push buttons here if you want.The second function is ui_check_slow_encoder, which is intended for rotary encodes connected over I2C. This is the only key macro you should add there. As you see,...
