This build uses an AM radio built into a small integrated circuit to detect some of those radio waves. An Arduino Nano receives the signal from the TA7642 IC and lights up a series of LEDs as it ...

The build is open-source, and designed to work with strings of 60, 120, or 180 WS2812B LEDs. An Arduino Nano is charged with running the show, capturing audio via its analog-to-digital converter.

Both boards are excellent options for circuit ... LEDs and buzzers to more sophisticated LCD and Wi-Fi modules. [Featured image by Raspberry Pi Foundation | CC BY-SA 4.0] The Arduino Nano is ...
