Topic: rotary input (Read 1 time) previous topic - next topic


Hi all, another case of "tell me what I'm thinking" please :-)

I want to use a rotary input like a pot to send a value to the Arduino.

I'll set a max and min but want to be able to rotate freely, i.e. the knob can continue to turn even after I have hit the min/max and it will take multiple turns to move from one extreme to the other.

I guess I'll just be sending an "I'm moving THIS way" or "I'm moving THAT way" signal.  Like a mouse wheel?

Not sure what component need though..can anyone advise?  Many thanks.


Sounds like you want to google rotary encoder.
The art of getting good answers lies in asking good questions.


Do your self a service and get an optical rotary encoder and save the trouble of debouncing a mechanical one.



Exactly what I was looking for and the Playground link gives some really useful explanations thankyou.
