We also recently were talking about hams experimenting with digital modes and this is a great example, both by the developers of FSQ and [jmilldrum] for implementing it with an Arduino.

He’s adding a digital display to a 1940s radio, and he’s doing it with Nixie tubes. The circuitry for the digital display for this AM radio requires getting the frequency the radio is tuned to.

The HamShield supports both voice and packet radio modes. You could even invent your own digital modes with enough skill. It is compact, lightweight, and works great with any Arduino or Arduino ...

Arduino enthusiasts looking for a new project to keep them busy over the weekend may be interested in a new Arduino FM Radio Project, which uses an ATmega328-based board to communicate with a ...

This voltage can be read by an Arduino digital input and then the Arduino can act upon it. The PIR Motion Sensor on the left is made by Parallax and sold by Radio Shack.

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 ...
