Developing applications that can perform complex tasks can be a challenging process, and it requires careful planning and design. One approach to managing this complexity is to use a Layered Architecture. This architecture separates the application's code into layers, each with a specific responsibility and purpose. These layers are typically organized in a hierarchy, with higher-level layers depending on lower-level layers.
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The NRF24L01+ is a newer version of the NRF24L01, capable of doing an extra 250kbps of on-air data rate while the one without “+” has only 1Mbps and 2Mbps.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.
Digital communication between devices is an essential part of modern technology. There are several protocols available for this purpose, each with their own strengths and weaknesses. Three of the most commonly used protocols are UART, I2C, and SPI. In this article, we will examine these three protocols, their advantages and disadvantages, and how they compare to each other.
AT commands, short for Attention commands, are a set of instructions used to control modems. These commands originated from the Hayes command set and have become essential for IoT (Internet of Things) devices, especially for managing WiFi modules. They allow users to perform functions such as connecting to a network, sending data, and configuring device settings, making them crucial for IoT applications.
Instant Payment Notification (IPN) is a message service that notifies you of events related to PayPal transactions. You can use IPN messages to automate back-office and administrative functions, such as fulfilling orders, tracking customers or providing status and other transaction-related information.
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.
Arduino, a well-known name in the world of electronics enthusiasts, offers a user-friendly platform for experimenting with electronic projects. Within the Arduino toolkit, the Arduino Integrated Development Environment (IDE) is a crucial component, featuring a valuable tool known as the Serial Plotter. In this article, we'll explore the practical applications of the often-overlooked Serial Plotter and how it serves as a dynamic and insightful tool for visualizing real-time data in Arduino projects.
The RF-Nano module is a compact, affordable module that combines an NRF24L01 wireless transceiver with an Arduino-compatible microcontroller. Using the NRF24L01 protocol, the RF-Nano operates on the 2.4 GHz band, making it a practical choice for creating simple, low-power wireless networks. This module is popular among hobbyists and engineers for tasks like home automation, remote control applications, and IoT sensor networks. It’s especially suited for applications where simple, secure data sharing between sensors or remote control devices is required and where a compact, low-cost solution is preferred.
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.
ChatGPT is a cutting-edge technology that brings new possibilities to the world of natural language processing. It can help users automate conversations, answer frequently asked questions, provide personalized recommendations, and improve customer engagement. With its cost-effectiveness, accessibility, and scalability, ChatGPT can be a valuable tool for any individual, organization, or developer looking to leverage the power of AI-powered conversation.
