From API to LED: CRYPT0MANIA

Cryptomania is a sculpture designed as commentary on the cryptocurrency pandemonium. It lights up based on the 1 hour price change (a percentage value) of a particular crypto-currency – Ethereum.

From API to LED: Duplex Communication

Friday night! The perfect time for expanding on the API-to-LED work from last week. The improvement now offers a more diverse set of information and utilizes duplex serial communication.

The result is that now we can now use a toggle-switch to see the 1-hour price change of either Bitcoin or Ethereum in the form of LED lights. The position of the attached toggle switch determines which currency is being shown.

The programming also features a p5 sketch that reflects the information being sent through the serial.

For example, in the video below Ethereum has had a modest positive 1 hour price change (0.06%), so it lights up the green LEDs a teeny bit. At the same time, Bitcoin has had a larger, negative price change (-1.16%), so it lights up the red LEDs quite a bit.
