IOT tool to send messages to dweet

We have created a new tool to send messages from the whiteboard to dweet.io . This will allow the whiteboard to become an IOT interface.

A use case could be to control an Arduino with its 37 + sensors.

No files, tests, or entry points are named. Start by locating the referenced whiteboard-to-dweet.io tool and confirm whether it exists, then clarify the intended message flow and Arduino use case. Done should mean an agreed, testable scope for sending messages and handling the proposed sensors.
