What would be the best way for a message to apprear on an lcd screen with a set start value, where you can adjust that value with a rotary encoder?

[nkrkv/encoder](https://xod.io/libs/nkrkv/encoder/) library has example using count node to track value. You could feed this to lcd instead of watch node. If you want non-zero initial value, you could add the start value to count output before feeding to lcd.

Initial value might be a good pin to add to count node for when you don’t want to reset to 0.
