The ESP8266 is a popular Wi-Fi microcontroller that can be easily programmed to build Internet of Things (IoT) devices. This tutorial will show you how to make an ESP8266 Internet clock with an LED matrix display. The watch will use the NTP (Network Time Protocol) to synchronize with an online time server and display the current time on the LED matrix.

Computer with Arduino IDE installed
Step 1: Connecting the LED Matrix Display
Start by connecting the LED matrix display to the ESP8266 development board. The connections are:
VCC to 3V3
GND to GND
DIN to D8
CS to D7
CLK to D6

Step 2: Install the Required Libraries
To make our ESP8266 Internet clock,. You can install these libraries by going to Sketch > Include Library > Manage Libraries and searching for Led control and untypicality.
Step 3: Writing the Code
Now that we have installed the required libraries, we can start writing the code for our ESP8266 Internet clock. In the Arduino IDE, create a new sketch and copy the following code:
