Remote Controlled Car

Description

This project is a 4-wheeled remote-controlled car built using Arduino, eletronics, motors, servos, legos, and cardboard. It allows users to control the car with a custom designed remote controller.

Key Features:

• Remote control via wireless communication.
• Rear Wheel Drive and Front Wheel Steering.
• Freedom of 20-25 degree steering.
• Custom LEGO steering system and custom LEGO holders for components.

Hardware Overview

The car is made up of the following components:

• Motor Driver: L298N motor driver for controlling motor direction and speed.
• Motors: 12V DC 200 RPM Motor
• Controller: Arduino Mega 2560
• Connectivity: NRF24L01 Transciever
• Power Supply: NiMH 12V and 9V Rechargable Battery

Software Overview

The software controlling the car includes:

• Motor Control: L298N Digital Pins that set direction and speed of motors.
• Remote Communication: NRF24L01 1-Way communication between controller and car.
• Steering Control: Standard Servo Library for Arduino

Main Scripts:

• carRecieverCode.ino: The reciever side that maps the controller inputs to the motor PWM output and servo steering positions.
• remoteCode.ino: The transmitter for sending data packets of controller inputs to the reciever.
