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.

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 ...

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 ...

“You can’t put new wine in old bottles” – so the saying goes. But you would if you’re a hacker stuck with a radio built in 2005, which looked like it was put together using technology from 1975.

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.
