No string attaches this tin can telephone

Arduino TeamJune 9th, 2020

Geoff (AKA Facio Ergo Sum) has created a new take on the classic “tin can telephone,” using an Arduino and nRF24L01 transceiver to pass audio signals instead of a physical string. 

The build and testing process are outlined in the video below, including poking holes for an antenna and talk button, as well as hot gluing everything in place.

More specifics can be found in Geoff’s project write-up, and along with the RF unit, it uses an Uno to run a transmission program. Batteries, a speaker, an amp, and a microphone are also implemented, enabling a pair of these cans to communicate from what appears to be well over 100 meters away.
