-The program on the PIR controller will publish "Motion detected" and "Nothing detected" messages to topic "security". +The program on the PIR controller will publish "Motion detected" and "Nothing detected" messages to the topic "security" when armed. To arm module, send to the topic "ESP53/pir" message "1". For disarming, send "0". The default value is "0". PIR module RED LED always indicating when motion is detected. 
-The OLED controller will then display those messages. + 
-If it receives message "Motion detected", buzzer shall be activated.+The OLED controller will then display those messages. It will print out anything it receives on "security" topic.
