While Internet of things (IoT), Industry 4.0, Machine to Machine communication etc are getting increasingly popular the need for wireless communication has become incumbent, with more machines/devices ...

In my last tutorial I created a NodeMCU based Duino Coin Miner. It is an awesome little miner that sits on my desk and mines few cents a day. However, adding these miners to my home network choked my ...

But, I was not happy with this solution. So, I did a bit of research and found this "NRF24L01 RF Transceiver Module" which I can use to create a mesh of wirelessly connected microcontrollers. In this ...

Bluetooth Low Energy (BLE) is a version of Bluetooth and it is present as a smaller, highly optimized version of the classic Bluetooth. It is also known as Smart Bluetooth. The BLE was designed ...

[Necromant] wrote a library to flash his microcontroller over an RF link using an NRF24L01 wireless communication module. The NRF24L01 is a cheap RF module that can be easily integrated into many ...

There’s an excellent chance you’ve already worked with the nRF24L01. These little modules are an easy and cheap way to shuffle data across a 2.4 GHz radio link at a respectable rate, making them great ...

Wireless data transmission enables many applications (e.g., in the field of home automation). However, the communication must be robust and reliable. This nRF24L01+-based PIR sensor project is a basic ...

When using 2-way communication between 2 RF modules, it is very useful to be able to detect loss of communication between the modules. Especially with remote sensing applications, you don't want to ...
