A radio, of course! Well, the project presented here is about building a compact Arduino FM Radio with the help of an astonishingly cheap (eBay) radio module. Recently, I built one for my needs and ...

DRA8x8 Radio Module Arduino Library Incomplete This is a small library which handles the configuration of the Dorji DRA8x8 radio modules (DRA808M, DRA818V, DRA818U). The datasheet for these modules is ...

DRA818U/V Radio Module Arduino Library This is a small library which handles the configuration of the Dorji DRA818 radio modules. The datasheet for these modules is somewhat lacking in details, and ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...

This comprehensive Arduino RFID tutorial teaches you how to interface RFID (Radio Frequency Identification) technology with Arduino microcontrollers using the popular RC522 RFID module. Arduino RFID ...

In this DIY session we are building a circuit to program the Arduino wirelessly using Bluetooth module HC-05. Here we are using an HC05 Bluetooth module to do this.

The Raspberry Pi compute module is a powerful piece of hardware, especially for the price. With it, you get more IO than a normal Pi, plus the ability to design hardware around it that’s spec… ...
