# ESP8266 LCD Clock (Wi-Fi + NTP)
This project is a **custom-character big digit LCD clock** using an **ESP8266 NodeMCU** with **I2C LCD**.
The time is fetched from the internet via **NTP** and automatically adjusted for **India Standard Time (UTC+5:30)**.
It also supports:
- **12-hour format with AM/PM**
- **Custom greetings based on time of day**
- **Multiple Wi-Fi credentials for reliable connection**
---
## ✨ Features
- Large custom-digit display using LCD’s CGRAM.
- Time updates from NTP every minute.
- Greets user with:
- `Good Morning` (6 AM to 12 PM)
- `Good Afternoon` (12 PM to 10 PM)
- `Good Night` (10 PM to 6 AM)
- Multiple stored Wi-Fi credentials — automatically connects to first available.
- Neatly arranged clock layout so AM/PM fits perfectly.
---
## 🛠 Hardware Required
- **ESP8266 NodeMCU**
- **I2C LCD Display** (20x4 recommended)
- USB cable & power supply
- Internet access
---
## 📦 Libraries Required
Install these libraries via Arduino IDE’s **Library Manager**:
- `ESP8266WiFi.h`
- `NTPClient.h`
- `WiFiUdp.h`
- `Wire.h`
- `LiquidCrystal_I2C.h`
---
## ⚡ How It Works
1. ESP8266 tries to connect to one of the stored Wi-Fi credentials.
2. Fetches time from NTP server (`pool.ntp.org`) with India time offset.
3. Displays the time in big digits on the LCD.
4. Shows a greeting message based on the hour of the day.
5. Refreshes every second for real-time updates.
---
## 🔧 Setup
1. Clone the repository:
```bash
git clone https://github.com/MaxonXOXO/CustomLCD.git
```
2. Open the `.ino` file in Arduino IDE.
3. Replace Wi-Fi credentials in the code:
```cpp
#define WIFI_SSID_1 "YourFirstSSID"
#define WIFI_PASSWORD_1 "YourFirstPassword"
```
4. Upload the code to your ESP8266.
5. Connect your I2C LCD to the correct pins and power up.
