Simple project for work together ESP01S and mobile device with Android 7+. This project allows you to control the light of the built-in LED of ESP - ON, OFF and set brigthness. ESP work as server(AP with SSID: Lights*(xxxxx), password: 1234567890 ). The server recognizes the requests addressed to it and according to them can execute a direct command (ON, OFF) or send a management interface. If changes are made to the settings, they are saved in the EEPROM after disconnecting. In case of power loss, the settings are read by the EEPROM.
