Many friends are big fans of remote control cars, because remote control cars are always fun to play with. But most RC cars focus on handling rough roads.So, in this one-of-a-kind project, we'll be building a speed-focused RC car using Arduino, with the goal of reaching maximum speed! We want it fast! convenient!We try out a coreless DC motor for a remote control car. These motors are commonly used in drones and are rated at 39,000 RPM, which should be enough to satisfy our thirst for speed.

PCB for Arduino RC Car

What is very interesting is that this PCB not only forms the circuit but also acts as the chassis of our car, providing the option to easily mount the motor.(Of course you can choose this PCB or design others yourself)

As you can see, this PCB can easily accommodate batteries, motors, and other components. You can download the Gerber file or even purchase it directly through the button next to this project

Assembling PCB

A picture of the circuit board after soldering is shown below.

Front and Back

Of course, we also need to 3D our motor mount and wheels for the robot. You can download the CAD file below for 3D printing.(Only suitable for this PCB)

Arduino RC Car Circuit Diagram

The complete circuit diagram for our Remote controlled Arduino Car is shown below.

RF Joystick for RC car using Arduino

The RC car will be controlled remotely using an RF Joystick.

This Joystick will also be built using an Arduino along with an nRF24L01 RF module, we have also used the Joystick module to control our RC in the required direction.

To build your Arduino RF Remote Joystick you can follow the below Circuit Diagram.

The RF joystick circuit can be powered using the nano board's USB port. The nRF24L01 module only operates at 3.3V, so we use the 3.3V pins on the Arduino. I have built the circuit on a breadboard as shown below
