This project sets up an Arduino Nano as a wireless receiver using an NRF24L01 module. It listens for control packets from a paired transmitter, parses the incoming data, and displays the values via ...

The FM receiver module is based on the TEA5767 [1, 2] chip. It is a well-known module that could be controlled via the I2C bus. It covers the FM frequency range from 76MHz to 108MHz. At the output, it ...

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive.

At Hackaday, we like to see build logs, and over on Hackaday.io, you can find plenty of them. Sometimes, though, a builder really outdoes themselves with a lot of great detail on a project, and ...

The build uses an Arduino, an MP3 chip, a SD card, LCD screen, amplifier, and two speakers. Everything is then packed into a small repurposed box with buttons and a volume knob. The end result is a ...

At about $30, the Arduino isn't an expensive device, but if you want to make your own, simpler version, electronics blog Hardware Startup shows off how to build an Arduino clone for less than $5.
