Coding the circuits

In the coding step, two more functions were added into the system. First is the online control mechanism. The Wi-Fi connectivity of the Photon enables me to program an online portal for users to view system status and turn it ON/OFF. The online function is called "Knok". User can type "ON" or "OFF" to control the system. The variable "system" indicates the system status (1 for on and 0 for off).

Second, I utilized the IFTTT service so that whenever the alarm even is sent to the cloud, users will receive an email notification so that they do not need to log in to the particle console to view the status.
