ESP32 Car Controller with Mobile App (Bluetooth)

This is my first project using ESP-IDF and ESP32, the project aims to develop a simple control system for a car using an ESP32 microcontroller. The car will be controlled remotely via Bluetooth using the mobile application.

Hardware Components:

1. ESP32 Board
2. L298N Motor Driver
3. 4 DC Motors
4. 3 Lithium ion batteries (3.7v / 1200mah)
5. Ultrasonic Sensor
6. GPS Module (I used NEO-6MV2)
7. Mobile Device

Software:

• ESP-IDF (development framework for ESP32)
• Mobile App (developed using react-native Thunkable)

Project Structure:

The components directory houses the project's core functionalities:

• controller: Contains logic for controlling the car's movement.
• DSP: Digital Sensor Process (DSP) Handles motor driver control and data sending/reading.
• Nimble: Manages Bluetooth Low Energy communication with the mobile app.
• ultrasonic: Handles communication with the ultrasonic sensor for obstacle detection.
• GPS: Coming Soon...
