This application is for controlling the SG90 servo connected to the Arduino ESP8266 family. Therefore, an Arduiono ESP8266 and SG90 servo are required in advance, and a program must be written to the ESP8266. Please refer to the source code for program samples. This is a program that sends String data to arduino ESP8266 by UPD. Please see below for the program on the arduino side. https://ios.iya.tokyo/031udp/ If the source remains the IP address is 192.168.4.1 port 8888 I think it will be It can be operated as below https://youtu.be/M9JkJ-v0i4E
