To connect the DELTA LC-Relay-ESP12-2R-D8 Relay Module to your Arduino board, you will need to follow these steps:

1. Make sure you have installed the Arduino IDE version 1.8.9 or the latest version on your computer.
2. Open the Arduino IDE and go to File > Preferences. In the Preferences window, enter the following URL in the "Additional Development Board Manager URL" field: http://arduino.esp8266.com/stable/pac...
3. Click on Tools > Development Board > Development Board Manager. In the Board Manager window, search for "ESP8266" and install the Arduino support package 2.5.2 or the latest version for ESP8266.
4. Connect the TTL serial port module (e.g., FT232) to your computer via USB.
5. Connect the TTL serial port module to the DELTA LC-Relay-ESP12-2R-D8 Relay Module as follows:
- Connect GND on the TTL serial port module to GND on the DELTA module.
- Connect TX on the TTL serial port module to RX on the DELTA module.
- Connect RX on the TTL serial port module to TX on the DELTA module.
- Connect 5V on the TTL serial port module to 5V on the DELTA module.
6. In the Arduino IDE, click on Tools > Development Board and select "ESPino (ESP-12 module)".
7. Open the program you want to download to the DELTA module.
8. Click on Tools > Port and select the correct port number for your TTL serial port module.
9. Click on "Upload" to compile and download the program to the DELTA module.
10. Once the program is downloaded, disconnect the IO0 and GND pins.
11. Power on the DELTA module again or press the reset button to run the program.
