# LED Matrix Retro Clock
A retro style clock with matrix LED display using an ESP32 microcontroller with automatic NTP time sync.
Renderings / Prototype:
| Front | Back | Isometric |
| ---------------------------------------------------- | ---------------------------------------------------- | --------- |
| 
| 
| 
|
## Features
- Displays the current time in HH:MM format
- 4 Digit LED matrix display (8x8 pixel)
- Customizable animations, dimming and
- Automatic time synchronization using NTP
## Hardware Requirements
- ESP32 (housing designed for USB C version)
- 4 digit 8x8 LED matrix display based on MAX7219 (FC16)
## Software Requirements
- PlatformIO
- MD_Parola (via PIO)
- ESPDateTime (via PIO)
- WiFiManager (via PIO)
## Mechanics
The only mechanical part required is the housing which consists of a front and a back piece.
### 3D-Printed Parts
| Filename | Thumbnail | Required |
| ---------------------------- | --------------------------------------------------------------------| -------- |
| `./print/front.stl` | 
| 1 |
| `./print/back.stl` | 
| 1 |
Printer settings:
- All printed parts designed for PETG.
- Best experience on my printer was to print the front upside down (the actual front of the case facing the print bed) as this does not require any supports. For a cleaner look you can consider to print it reversed with ironing enabled but note that this requires a lot of support material.
- Using fuzzy skin for all outside walls creates a nice touch
- No rafts/brim etc. reguired for any model.
### Required screws
| Name | Spec | Required | Notes |
| ----------------- | ----------------------------- | -------- | ------|
| countersunk screw | M3 5mm, e.g. DIN EN ISO 4762 | 4 | To attach ESP to back of housing |
| countersunk screw | M3 10mm, e.g. DIN EN ISO 4762 | 4 | To attach display to back of housing |
| countersunk screw | M3 10mm, e.g. DIN EN ISO 4762 | 4 | To fix back and front of housing |
### Assembly
All electronics are screwed to the back of the housing, finally the front of the housing is snapped into the back and tightened via the screws from the back.
## Installation
1. Clone the repository:
```sh
git clone https://github.com/yourusername/Matrix_Clock.git
2. Open the project in PlatformIO.
3. Wait for PIO to configure and download the required libraries
4. Compile and upload the project to your ESP32 microcontroller.
## Usage
- Power on the ESP32.
- On first usage only: Configure the ESP to your local WiFi. For this, connect to the ESP's access point and use the default configuration page to enter your WLAN SSID and password
- Wait for NTP sync
- The current time will be displayed on the LED matrix.
