+Introduction to MicroPython
+============================
+JR Rickerson
+
+Overview
+--------
+MicroPython is a reimplementation of the Python 3 language for micrcontrollers.
+The Kickstarter project provided a copy of the MicroPython code embedded on a
+a small microcontroller board called the "pyboard," and a Python module to
+provide access to the components on the board.
+
+Slides
+------
+Slides are available via Google Docs: 
+https://docs.google.com/presentation/d/1Y3Wslr_so9h0rhLIcHzoOU1z7XNXuJMO1-rfwCNNMuM/edit?usp=sharing
