RC CAR CIRCUIT USING L293D MOTOR DRIVER

This project simulates a 4-wheel drive RC car using four hobby DC gear motors, controlled via two L293D motor driver ICs, and an Arduino UNO. Each motor driver controls two motors, enabling independent control of all four wheels for enhanced mobility, better traction, and stable movement. The project is built and simulated in Tinkercad Circuits.
This system forms the basis of a robotic car chassis which can be extended to include Bluetooth, IR, or ultrasonic sensors for autonomous behavior.To design a 4WD RC car model using Arduino that controls four DC gear motors via two L293D ICs. The car can move forward, backward, left, right, and stop, using programmable logic simulated in Tinkercad.

1 × Arduino UNO
2 × L293D Motor Driver ICs
4 × Hobby Gear Motors (DC motors)
1 × Breadboard
External Power Supply (9V battery or 5V source)
