That’s a Bluetooth wireless small sensorium. The code to support this is a bit hacky as rxtx doesn’t seem to want to play with Bluetooth serial ports, but it works.
The code is in the repository:

Next I need to wired up the LEDs directly.
Then a WiFi Arduino that could work with Thingspeak directly. And multiple sensoria could interact.
