- Wed Feb 08, 2017 5:19 pm #62277 Hello!

Im new at Arduino and now im trying to get a program working.
(the program will read data from my Iphone get GPS position from it. Im using ESP8266-01 to connect the phone and the Arduino..... then the program will calculate the heading from two GPS positions... then i will have a stepmotor or a servo pointing in this direction.)

i have got a program that transfer the GPS from phone to Arduino working....
I have got a program working with the servo....

But when i put this two together somthing strange happens to the Digital ports...
The servo turning each time the ESP8266-01 is getting data or sending data....

I have connected the ESP8266-01 to the 3V and even tried to have external power to it....
Nothing makes the servo stop turning when the wifi is working.
