-// PIR Motion Sensor Alarm + ESP8622 WiFi Module + FRDM-k64f
-//PIR sensor can detect change on its surrounding by measuring the change of infra red
-// Then will send high=1 to the FRDM-k64f to flash the LED, Run the Buzzer,
-//Send information through UART serial Port to Tera Term and display how many motion been
-//detected,also will send information to Thingspeak IoT website using WiFi connection
