Initial Design:

The Initial Design incorporated the PIR Motion Sensor, the LED, and the resistor. The goal of the initial design was to notify the user that motion was detected by enabling the LED. I found that the user (my parents) did not want to constantly have the LED blinking on and off. The backdoor isn't always opened, so there needed to be a switch to turn off the device when not in use.  I addressed this challenge by deciding to incorporate a sliding switch into my Final Design.
