I’ve decided to build a single PCB board that embeds the brain (arduino) and the radio module (nRF24L01+) and is low power capable.

The circuitry used is simple: [Kevin] simply wired up two Arduino Unos with nRF24L01 radio modules, which communicate over SPI.

A single button on the Arduino helps cycle through a range of preset frequencies stored in memory. The Arduino connects to the FM radio module over I2C.

In this module, you will wire a mobile platform and a remote to control the mobile platform. The remote uses a joystick to read in user input, which then sends the joystick’s position to the mobile ...

The NRF24L01+ Arduino wireless transceiver shield is ideal for a wide range of applications. For instance, it can be used in home automation projects to control lights, fans, and other appliances ...

Ever wanted to build an FM radio? Armed with an Arduino and a RDA5807M FM radio module, T. K. Hareendran shows us how to get started.

Short-range radio specilaist LPRS has introduced a stacked module that allows Arduino boards to communicate wirelessly with other Arduino boards or PC hosts. The system uses the supplier’s easyRadio ...
