WEEK 1

 

PURCHASING COMPONENTS 

  

     I continued FYP 2 in the first week of this semester by developing the project prototype. My first step was to purchase the project materials. To increase efficiency, several changes have been made from what was recommended in FYP 1. The Raspberry Pi 4 Model B, LM393 sound sensor, and Raspberry Pi Camera are among them.
