This document describes the development of an autonomous electric car controlled by a microcontroller and Android app. The car can operate in either manual mode, controlled by a user, or autonomous mode, controlled by the microcontroller receiving instructions from the app via Bluetooth. The app allows the user to select the mode and send commands to control the car's movement and sensors. The microcontroller code executes these commands, controlling the car's motors and reading sensor data to enable autonomous operation. The project combined skills in motor control, microcontroller programming, communication protocols, and app development to create a functioning prototype autonomous vehicle.
