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 ...

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 ...

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 ...

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 ...

[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 ...

3D print and build an Arduino Pistol-grip Transmitter for controlling Remote Control cars. Today, we’re assembling and wiring a 3D printed Arduino-based pistol-grip radio transmitter that operates ...

Awesome electronics developer Patrick Thomas Mitchell has once again returned to Kickstarter to launch his new NRF24L01+ Arduino wireless transceiver shield. This innovative shield offers a wealth of ...
