Before we get started it is important to understand that there two types of nRF24L01 modules available in the market one is called just nRF24L01 and the other is called nRF24L01+ PA+LN. While both the ...

Abstract: This paper proposes a Vehicle-to-Vehicle (V2V) communication system that utilizes Arduino Uno, nRF24L01 wireless transceiver, GPS Neo6m module, and an HTML/CSS/JavaScript map interface. The ...

[导读]射频通信是物联网应用中最常用的通信技术之一，我们之前在两台Arduino之间的通信中使用了433 MHz的射频模块。在本教程中，我们将使用NRF24L01收发模块在Arduino板和NodeMCU之间进行无线通信。在这里，我们将使用NodeMCU ESP8266从互联网服务器获取实时时间戳 ...

[导读]有各种无线通信技术用于构建物联网应用，RF(射频)是其中之一。nRF24L01是一款工作在2.4 - 2.5 GHz (ISM频段)的单片无线电收发模块。该收发模块由一个完全集成的频率合成器、一个功率放大器、一个晶体振荡器、一个解调器、一个调制器和增强的ShockBurs协议 ...

Abstract: Wireless technology has completely changed how we interact with gadgets, enabling remote control of electrical and electronic items. Since wireless communication technology has advanced, it ...

Despite the name, Bluetooth Low Energy (BLE) has very little to do with the original Bluetooth, other than its use of the same 2.4 GHz frequencies. This is where [Dmitry] got the idea to use a 2.4 GHz ...

We’ve already covered inexpensive offline voice recognition modules based on US516P6 or TW-ASR ONE microcontrollers that allow people to add smarts to their projects without a network connection for ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...
