+## Week 6
+
+
+##Week 6 Labs: 
+
+**PART ONE:** 
+
+In this folder you will find a base circuit for the MPR121 breakout board. To get the library and watch the video on how it works go here: <http://bildr.org/2011/05/mpr121_arduino/> 
+
+Working in groups, try out the MPR121 capacitive touch board. Create a circuit digram and video of any creative idea you have that make some output respond to physical touch. People can leverage cooper tape, conductive paint, tinfoil or any other metal surface like a row of stairs with a metal strip on them. Be creative and have fun! 
+
+**Part Two** 
+Scopes and signals 
+
+Try to generate a wave form on the scope - play with seeing what data you get out of your sensors
