 * Stable PIR signal
-** We had trouble putting the LPC to sleep since the PIR Sensors kept outputing analog signals even when inactive (Noise). So we had to develop logic to create a min/max values for a specific period of time to trigger the deactivation of sleep.

 * 3D print quality
 ** We had to create multiple iterations to make the housing Fit our devices. We still need to make more exact measurements to fit our components.

 == Conclusion ==
-Conclude your project here.  You can recap your testing and problems.  You should address the "so what" part here to indicate what you ultimately learnt from this project.  How has this project increased your knowledge?
+This project really helped us understand the capability of the sleep modes on the LPC system. It can definitely be used in several applications to save battery life. It is very simple to implement if you read through the data sheet completely. We would have also liked to implement the sleep mode in the Beagle bone to get a true power reading but didnt want to invest too much time in learning the beagle bone, but rather learn the LPC sleep modes as a proof of concept.

		+	Please note the following, regarding the interaction between power modes and debugging status. If P2.10/EINT0/NMI is asserted voltage-low, the LPC will boot in debug mode. In debug mode, the LPC will not wake in the same manner. Since we do not program the LPC via JTAG/SWD, this is not a problem for us.
