# 🚗 Bluetooth Controlled Arduino Car Project

This is a DIY Bluetooth-controlled car built using an **Arduino Uno**, **HC-05 Bluetooth module**, and **L298N motor driver module**. The car is wirelessly controlled via a smartphone Android app and is perfect for beginners in robotics and embedded systems.

---

## 🔧 Features

- Wireless Bluetooth control using HC-05

- Motor control via L298N H-Bridge

- Forward, backward, left, right, stop, lights commands

- Compatible with Android/Iphone smartphone apps

- Modular and expandable for future upgrades

---

---

## 💻 Arduino Code

The Arduino sketch is located in the `car_code/` folder:

- File: `Source Code.txt`

- File: `Source Code.ino`

It records characters sent via Bluetooth and drives the motors accordingly.

**Sample Commands:**

- `F` → Forward

- `B` → Backward

- `L` → Left

- `R` → Right

- `S` → Stop

- `Y` → Front Led On

- `y` → Front Led Off

- `Z` → Back Led On

- `z` → Back Led Off

---

## 📱 Android App Control

The Car Currently Supports only Android Software

The APK File is located in the `Application/` folder:

- APK : `BTCAR.apk`

---

## 🚀 How to Run

1. Upload `Source Code.ino` to the Arduino Uno using the Arduino IDE.

2. Power the car with a battery pack (avoid USB during motor operation).

3. Pair HC-05 with your phone (`Default password: 1234` or `0000`).

4. Open your Bluetooth controller app and connect.
