That simple, one line of code has so much power and flexibility.
streamer.log("[Event Stream Name]", "[Value]")
Every stream that shares the same "event stream name" is grouped together and viewed in applications such as Waves. The type of value used will determine how your stream is visualized (capture numbers, strings, booleans, etc). See your data as lines, waveforms, bits, flags, or strings. Stream anything your code has access to (sensor outputs, hardware connections, software variables). See everything.
