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.

The physical part of the controller is finished but what about the brain? Once more, our decision falls on Arduino Nano. It perfectly fits by size providing all the necessary functionality. For programming a Nano board we need a USB to serial interface which can be hooked up to the programing header located on the top side of our controller.
Based on the solution of designing multi-functional remote controller and being aware of the needs we started building the joystick. The cover with controls is ready for use but we miss the most important part: the microcontroller. Once more, our decision falls on Arduino Nano. It perfectly fits by size providing all the necessary functionality.
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.
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.
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.

MPU-9250 is one of the most advanced combined accelerometer, gyroscope and compass small size sensors currently available. It replaces the popular MPU-9150 lowering the power consumption, improving gyro noise and compass full scale range performance. It has many advanced features, including low pass filtering, motion detection and even a programmable specialized processor.
Modern web frameworks take one group of related concepts and split it across multiple places throughout your codebase. Laravel provides a very clear structure with large variety of tools to make the development easier and faster. Along with the huge community it makes Laravel a great option for most starting projects.
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language and the Arduino Software (IDE).
Historically a lot of software has used incrementing numbers to represent the identifier of a particular piece of data. They can be auto-generated by many data stores, they are easy to read, efficient to store and naturally time ordered.
As time passes, applications become larger. They need more resources and usually distributed in different places. That may cause some errors generating concurrent numbers and coordination issues. Incremental numbers can also be the source of security problems and they may include implicit information about datasets volume. Modern software architectures also trend to decouple infrastructure layer and move ID generation logic to the domain core.
