Playing audio from a Boldport Cuttle (Arduino) over LiFi with lite2sound
Here's a quick demo..
NB: or just a short CuttleTalk clip
Now I've built the Boldport lite2sound, time to test it out. I'm inspired by LEAP#417 SimpleSamplePlayer to attempt some LiFi audio transmission by light.
I'm using the Boldport Cuttle (an AVR/Arduino clone) to transmit an audio sample with an LED, and the Boldport lite2sound as a receiver. The audio out from lite2sound is amplified with LEAP#210 TDA7297 Kit
W00t, and it works;-)

The LiFi broadcast is simply a Cuttle with a high-intensity white LED on pin 11/PB3 and a 220Ω current limiting resistor:
