#  HackaTime Live Tracker (ESP8266 + LCD)

This project connects an **ESP8266 (NodeMCU)** to [HackaTime](https://hackatime.hackclub.com) to display **real-time coding stats** on a **16x2 LCD screen** and alerts using a buzzer.

It shows your:
- 🔴 **Live project** name + seconds coded
- 🔁 **Most used project**
- 🕒 **Total coding time**

A button lets you switch between these 3 views.
