hey guys im new to the whole arduino stuff i know some little things but not alot. i got a small project where i need to show the rpm on a lcd display with an rotaery encoder. i tried to search it on yt and google but i didnt found any similair projects is someone willing to help me?
thanks in advance!
and sorry for my bad english
Yes, helping people is part of the forum's purpose... but we don't like having to do all the work for ANYONE.
take baby steps. take a look a the Blink sample project first, then try to get your LCD working, then add the interface to the rotary encoder.
If you have questions about how to use your LCD and/or encoder, we need to know the specifications of each. By that I mean links to data or spec. sheets.
You will likely need libraries to interface to your LCD and encoder. Those libraries will have example code to help get going.
I have not used encoders, so can't recommend a library, but maybe someone who has used them will share their favorite encoder library once we know what you have.
For what it's worth, typically digital readouts of RPM don't work very well since as soon as the rpm fluctuates (like it does all the time with a car engine for example), the digits become difficult to read. That is why many tachs are either an analog meter of some sort or a bar graph - trying to read rapidly changing numbers is very tough.

im not sure yet if im going to use a encoder. the rpm i needed to measure is mounted in a frame so im not sure yet if im going to use a sensor or a encoder. forgot to mention that sorry.
i saw a lot of different rpm lcd project and most of them are using a sensor while there is a thingy mounted on the motor shaft.
