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 ...

Who does not love photography! There are lots of subjects in this creative field and each one is unique, let's choose one. How much all of us love to see wild animals on National Geography or ...

In the era of Internet of Things (IoT), wireless communication is getting increasingly popular in everyday life. Nowadays, devices can talk to each other over the cloud or local network. When we talk ...

[Ralph] wasn’t satisfied with the required 5 control pins to drive his nrf24l01+ transceiver module, so he used this circuit needing just 3 pin using an ATtiny85. One of the key components was to ...

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 ...

[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 ...
