ESP8266 Community Forum

I am just getting into the Ardunio and ESP8266 area, so I am sure this a complete newbie question. I recently tried to create a simple wifi enabled servo control sketch that would be loaded onto the Arduino. What I noticed is whenever the ESP8266 did either a read from a website or alternatively acted as a webserver taking in a GET posted response, the attached servo twitched quite a bit. It is almost as if the read/write functions were triggering the attached servo control pin.

Not sure if that is clear enough but I hope I am asking in the right general area.

Thanks.

What does your power source look like that is powering the environment? The WiFi abilities of the ESP8266 can draw current (I think I heard 200ma during operation). When WiFi traffic is being received or sent that may cause an additional load to your power supply and if it is not sufficient to maintain the current flow, it will cause problems in the environment as a whole. Also consider attaching a capacitor (say 10uF) across the supply rails to smooth out any sudden changes.

I have an adapter with 9V/650ma output to the Arduino board. I'll have to try the capacitor, kinda miss having a local electronics shop.

mholzma,
Did you get your servo controller working on esp8266 stand-alone (no arduino)?
I have a project where I want to do something similar, only way simpler (open/closed/status only - nothing in between).
Did you get your "twitch" figured out?
