Having two or more Arduino boards be able to communicate with each other wirelessly over a distance opens lots of possibilities like remotely monitoring sensor data, controlling robots, home automation and the list goes on. A good, reliable and inexpensive solution is NRF24L01.

The NRF24L01+ is a newer version of the NRF24L01, capable of doing an extra 250kbps of on-air data rate while the one without “+” has only 1Mbps and 2Mbps. Both versions can be mixed together as long as 1 or 2 MBps is being used as the data rate.

The E88 Pro Drone is an exceptional flying device that combines advanced features, reliable performance, and a user-friendly design. Built with innovation in mind, this drone offers an immersive aerial experience for beginners and enthusiasts alike. Operating the E88 Pro Drone is a breeze, thanks to its intuitive controls and user-friendly interface. The drone can be easily controlled using a dedicated remote controller or a smartphone application. The remote controller offers precise maneuverability, while the smartphone app provides a comprehensive set of features and flight modes. From automated flight paths to real-time video streaming, the app enhances the drone piloting experience and unlocks advanced functionalities.

The physical assembly of the car has been completed with all the components properly installed and ready for use. The next steps involve reprogramming the Arduino Nano with the appropriate software to enable all the features, including pairing the car with the AirControl joystick via the NRF24L01 module.

Radio control cars are small vehicles powered by electric or gas motors that can be remotely controlled by a transmitter. The transmitter sends signals to a receiver on the car, allowing the operator to control the car's speed, direction, and steering. Radio control cars are available in a variety of sizes, from miniature models that can fit in the palm of your hand to large off-road vehicles that can climb over rough terrain.

MongoDB is a popular open source and document oriented database system. It belongs to a family of databases called NoSQL, which is different from the traditional table based SQL databases. It makes use of collections, each having multiple documents, and allows the user to store data in a non relational format. Data is stored in flexible, JSON-like documents where fields can vary from document to document. That's the reason for calling it schemaless database.

Controlling devices over a distance opens lots of possibilities. Our Arduino roadmap contains many projects that must be controlled remotely and sometimes on a long-distance. Of course, it can be done with a PC but our experience has shown that it becomes complicated when you need long way, portable and rapid communications. Our solution was designing a multi-functional remote controller, we have called it AirControl. Aware of the needs it will have 4 push buttons, 2 switch buttons, 2 potentiometers and two analog modules. Additionally, each analog joystick module has integrated push button.

Wireless communication implies having a transmitter, in our case the joystick, and a receiver. We must build a simple circuit with NRF24L01 wiring that will act as listener for our joystick. The NRF24L01 module strictly needs 3.3V but the logic pins are 5V tolerant. That why we recommend to use the NRF24L01 adapter which acts as regulator, keep the voltage stable, apply filtering and reduce noises.

With the idea of making a remote-controlled car in mind, we began our investigation by disassembling the frame to uncover its internal components and understand how they work. By gaining a clear understanding of the car's original configuration, we were able to approach the modifications with greater confidence, knowing what changes were necessary and how they would integrate with the existing system.

Based on the solution of designing multi-functional remote controller and being aware of the needs we started building the joystick. It will have 4 push buttons, 2 switch buttons, 2 potentiometers and two analog modules. And, additional 2 push buttons integrated on the analog joystick module.
