Magic Mote MSP430G2553 wireless sensor node with NRF24L01+ module

Wednesday, April 12th, 2017

Tom from Magic Smoke writes: This is my first time designing a PCB for MSP430. I really like the NRF24L01+ booster pack but I would like something smaller to use for remote temperature sensors. With that in mind I've designed a 24.5 x 50 mm PCB (2 on a 5x5...

RC boat with NRF24L01+ and Arduino

Friday, August 19th, 2016

Markus Gritsch writes: I and my little son built a small electric boat from a kit. However, the kit only offered turning on the motor with a switch, and let the boat cruise wherever fortune it may take. I thought why not improve it a bit by adding some RC...

nRF24L01+ 2.4 GHz wireless connectivity with the tinyK20 board

Thursday, March 17th, 2016

Erich Styger writes: I’m using the tiny and inexpensive Nordic Semiconductor nRF24L01+ transceiver (see “Tutorial: Nordic Semiconductor nRF24L01+ with the Freescale FRDM-K64F Board“) in many projects: it costs less than $3 and allows me to communicate with a proprietary 2.4GHz protocol in a low power way (see “IoT: FreeRTOS Down to...

TinySensor server

Wednesday, July 1st, 2015

Steve's TinySensor server project, that is available at Github: Well after almost a year I decided it was time to update this project with improvements to both its hardware and software. On the hardware side, the server is still the original Raspberry Pi model B, but I've mounted the nRF24L01+ radio...

KeySweeper – covert Microsoft wireless keyboard sniffer using Arduino and nRF24L01+

Monday, March 23rd, 2015

Samy Kamkar has written an article detailing the build of his KeySweeper project: KeySweeper is a stealthy Arduino-based device, camouflaged as a functioning USB wall charger, that wirelessly and passively sniffs, decrypts, logs and reports back (over GSM) all keystrokes from any Microsoft wireless keyboard in the vicinity. All keystrokes are logged...

Power plug energy meter – Now wireless!

Thursday, January 15th, 2015

Kalle Löfgren writes: Today's post will cover how I managed to get an Arduino pro mini (3.3V) to sniff the energy meters SPI and transmit the data wirelessly with a nRF24L01+ to an Arduino Nano connected to a computer. The neat thing with this setup is that the Arduino pro...

Using touch screen as remote control

Monday, April 7th, 2014

Bajdi  wrote an article on using an Arduino Due with a 5inch touch screen and a wireless nRF24L01 transceiver as a remote control: One of the things I wanted to try out was using the touch screen as a remote control. I have a lot of cheap nRF24L01 modules so I...

Portable library for cheapie nrf24L01+ wireless module

Wednesday, May 1st, 2013

Kehribar released a C-based portable nrf24L01+ library on GitHub: I tried to make this library as portable as possible therefore, in order to use this library, you only need to define couple of GPIO functions in your project and that's it! Moreover, this library supports auto-retransmission and auto-ack features of...

App note: nRF24L01+ 2.4GHz wireless transceiver

Sunday, November 20th, 2011

The nRF24L01+ ICs are 2.4GHz transceivers that only need a few external parts. They're controlled by a simple SPI protocol, and two extra pins. The IRQ pin signals when data is available and can be used to wake a microconroller with an interrupt.  The CE pin is an input activates/deactivates...
