In this project, we will demonstrate how to interface a single LED (Light Emitting Diode) with an ESP8266 board. <\/p>\n\n\n\n

The ESP8266 board will be programmed to control the LED and make it blink at a specific rate.<\/p>\n\n\n\n

    Code Explanation:<\/h3>\n\n\n\n
      \n
    1. The ledPin variable is declared and set to 5, which corresponds to the GPIO pin connected to the LED on the ESP8266 board.<\/li>\n\n\n\n
    2. In the setup() function, the ledPin is set as an output using the pinMode() function.<\/li>\n\n\n\n
    3. The loop() function is where the LED control happens.<\/li>\n\n\n\n
    4. The LED is turned on by setting the ledPin to HIGH using digitalWrite().<\/li>\n\n\n\n
    5. The program waits for 1 second using delay(1000).<\/li>\n\n\n\n
    6. The LED is turned off by setting the ledPin to LOW.<\/li>\n\n\n\n
    7. Another 1-second delay is added.<\/li>\n\n\n\n
    8. The loop repeats, toggling the LED on and off continuously.<\/li>\n<\/ol>\n\n\n\n
