+// 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
