ESP8266 Community Forum

Hello all.

I am just getting started with esp8266 nodemcu.
I have enjoyed Arduino and nrf24l01, so I have some idea.
My question has to do with servo control.
How would one go about using an esp and potentiometer on one end to control a servo and esp on the other end? Are there any servo control code or project examples that do this with one esp talking to and controlling the other? I find several examples using a phone or PC/laptop.

Thanks for pointing me in the right direction!

Not sure how to accomplish the software end but I'd look towards using what is called a pulse generator.

On the input end, and a stepper on the output end, on cnc machines there is usually a 3 position switch that makes each "click" either .0001, .001,or .01 inch movement per click. With a micro stepping stepper controller you could get 1/10 step and full steps per click at least. Stepper motor would be rotary output of course.

The regular arduino servo commands work out of the box in the arduino environment.

The esp analog read function will return a value between 0 and 1023.
