Hi, I know very little about electronics and researched rotary encoders for a couple of days.
My project is to replace a non working turning knob on an appliance interface. I desoldered the rotary encoder and looked at its behavior
It is of the type where when you click from one indent to the next it will go low on A followed by B ( and vice versa ) and then go back to supply voltage (quadrature encoder). I searched long and far but there is no exact replacement available (PIN distance, mount orientation, shaft length etc. )
So I got a different encoder, a wheel from one of the maker suppliers. This encoder behaves differently. When you go from one indent to the next it will turn A low B high and the next indent A high B low. I am trying to research a circuit where I could make the new encoder behave like the old one. I do know programming, but do not want to use a microcontroller and instead learn how to do this in electronic components. This is about learning for me.
I thought about a RC circuit that pulls A up automatically after it went low, but the encoder has this alternating behavior where the next indent I would need to pull it high ( or something )
I saw a Youtube video "How To Use A Rotary Encoder Without Software" where the person shows some tricks with electronic components. It's not the easiest to understand for a beginner and either way his output is not what I need.
Can somebody guide me along how to do this best?
P.S. If I was not clear this is part of an interface board for an appliance where the original encoder is mounted on a round circuit board with 3 cables. Ideally the new encoder and circuit would be just drop in and work with the existing board. It looked to me like the main interface board has some debounce RC filters for A and B. So this would still be active I guess.
