Installation

This project is designed to work with 4-channel relay module, which uses an onboard MCU that controlls the relays according to the commands received from ESP-01 over UART.

0. Make sure that ESP8266 Core is installed in your Arduino IDE.
1. Open src\RelayControl\RelayControl.ino
2. Customize SSID and PWD for STA mode:

wifiMulti.addAP("ssid_from_AP_1", "your_password_for_AP_1");
wifiMulti.addAP("ssid_from_AP_2", "your_password_for_AP_2");
wifiMulti.addAP("ssid_from_AP_3", "your_password_for_AP_3");

3. Customize SSID and PWD for AP mode:

const char *ssid = "RelayControl";
const char *password = "RelayControl2020";

4. Set board settings

5. Compile and upload the code
6. Upload webserver to SPIFFS using Tools/ESP8266 Sketch Data Upload
