Desk clock using NTP time server esp8266 esp32.

LED matrix desk clock, auto time syncing updating. Red led matrix panels.

I stripped out the last code and produced this so you can follow it easy. Made a school boy error using a FONT file and wasted alot of time.

Would welcome any comments

he ESP8266 is a low-cost, Wi-Fi-enabled System-on-Chip (SoC) microcontroller manufactured by Espressif Systems, ideal for Internet of Things (IoT) projects due to its integrated Wi-Fi capabilities and affordable price. It features a built-in TCP/IP stack, allowing it to connect to networks, and can host its own applications or be used to add Wi-Fi functionality to other devices, making it a popular choice for DIY electronics and rapid prototyping.

Key Features & Capabilities:
Wi-Fi Connectivity:
Supports the 802.11 b/g/n protocol, enabling it to act as a client or access point to a Wi-Fi network.

Microcontroller Functionality:
Includes a 32-bit Tensilica Xtensa processor and memory, allowing it to run embedded applications.

TCP/IP Stack:
Has a full TCP/IP stack, simplifying network communication and making it IP-addressable.

Programmability:
Can be programmed with its own code, supporting platforms like Arduino IDE and MicroPython, or controlled using AT commands via a UART interface.

General-Purpose Input/Output (GPIO):
Features multiple GPIO pins for interfacing with sensors, LEDs, and other electronic components.

Affordable Price:
Its low cost makes it accessible for hobbyists and developers to incorporate wireless capabilities into various projects.

Common Uses:
IoT Projects: Widely used for creating connected devices that can monitor and control things over the internet.


A MAX7219 LED matrix is a module that combines an 8x8 LED dot matrix display with a MAX7219 integrated circuit (IC) to simplify control for microcontrollers like Arduino or Raspberry Pi. It allows hobbyists to display characters, symbols, and simple animations by individually addressing the 64 LEDs, using only three data pins and supporting "daisy-chaining" to connect multiple modules into larger displays for scrolling messages and more complex visuals.

How it works:
8x8 LED Matrix:
The display itself is a grid of 64 individual LEDs (8 rows x 8 columns) arranged in an 8x8 pattern.

MAX7219 Driver IC:
Instead of connecting 64 wires for each LED, the MAX7219 IC handles the complex job of activating and deactivating each LED. It does this by using multiplexing, which quickly scans through the rows and columns to illuminate the correct LEDs without needing a separate wire for each one.

Serial Interface:
You control the MAX7219 with a simple, 3-wire serial interface (typically DIN, CLK, and CS) from your microcontroller.

Daisy-Chaining:
A key feature of the MAX7219 is its ability to be "daisy-chained" or connected in series. You can connect the data output (DOUT) of one module to the data input (DIN) of the next, allowing you to expand your display to create a much larger panel with more LEDs, all controlled by the same three pins from your microcontroller.

Key benefits:
Simplified Control:
It drastically reduces the number of pins required from a microcontroller to drive a complex display.

Versatile Display:
You can program it to show a wide range of content, from numbers and letters to simple emojis and scrolling text.

Scalability:
The ability to daisy-chain modules allows for easy expansion to larger displays for projects like digital signage or message boards.
