WEEK 6 (Troubleshoot Circuit)

Hardware testing involved a systematic approach to built interfacing circuit which is beginning with testing the component and connection.After the connection is functional, the full circuit is construct. However, there are a few problems faced during the hardware development such as the speaker is not functioning and the connection loss between control panel circuit and GSM modem that cause the alert message was not delivered. . Then the circuit was troubleshoot by changing the speaker and RS 232 cable with the new one and solder it to the circuit as shown in figure below.
